A State Public Service Commission conducted a detailed employment survey across three major districts: District A, District B, and District C. The total workforce across all three districts combined is 100,000100,000.

- District A accounts for 40%40\% of the total workforce, and the ratio of male to female workers in District A is 3:23 : 2.
- District B has a total workforce that is 25%25\% greater than the total workforce of District A. Females constitute 44%44\% of District B's workforce.
- District C comprises the remaining workforce across the three districts, with a male-to-female ratio of 3:23 : 2.
- Across all three districts combined, 25%25\% of the total female workforce is employed in the government sector.
- Specifically, 30%30\% of females in District A and 20%20\% of females in District B are employed in the government sector, while the remaining government-employed females work in District C.

Based on the given information, what is the ratio of the number of female government sector workers in District C to the total number of male workers across all three districts combined?

Show answer & explanation

Answer: 13:58013 : 580

Answer

The ratio of the number of female government sector workers in District C to the total number of male workers across all three districts combined is 13:58013 : 580.
The total female government workers across all districts is 10,500 (25% of 42,000 total females). Subtracting District A's 4,800 and District B's 4,400 yields 1,300 government females in District C. The total male population across all three districts is 58,000 (24,000 + 28,000 + 6,000). The ratio 1,300 : 58,000 simplifies directly to 13 : 580.

Step-by-Step Solution

1
Calculate total workforce and gender breakdown for District A
Total workforce of District A = 40%40\% of 100,000=40,000100,000 = 40,000. With a Male:Female ratio of 3:23:2, Male workforce = 35×40,000=24,000\frac{3}{5} \times 40,000 = 24,000 and Female workforce = 25×40,000=16,000\frac{2}{5} \times 40,000 = 16,000.
Establishing District A numbers is required as the baseline for District B and total female count.
2
Calculate total workforce and gender breakdown for District B
Workforce of District B = 1.25×40,000=50,0001.25 \times 40,000 = 50,000. Female workforce = 44%44\% of 50,000=22,00050,000 = 22,000. Male workforce = 50,00022,000=28,00050,000 - 22,000 = 28,000.
District B's population is given relative to District A.
3
Determine workforce and gender breakdown for District C
Workforce of District C = 100,000(40,000+50,000)=10,000100,000 - (40,000 + 50,000) = 10,000. With Male:Female ratio of 3:23:2, Male workforce = 35×10,000=6,000\frac{3}{5} \times 10,000 = 6,000 and Female workforce = 25×10,000=4,000\frac{2}{5} \times 10,000 = 4,000.
District C contains the residual workforce from the total 100,000100,000.
4
Calculate overall male and female workforce totals
Total Male workforce = 24,000+28,000+6,000=58,00024,000 + 28,000 + 6,000 = 58,000. Total Female workforce = 16,000+22,000+4,000=42,00016,000 + 22,000 + 4,000 = 42,000.
The total male workforce forms the denominator of the required ratio.
5
Calculate government-employed females in District C
Total Female Government Workers = 25%25\% of 42,000=10,50042,000 = 10,500. District A Female Government Workers = 30%30\% of 16,000=4,80016,000 = 4,800. District B Female Government Workers = 20%20\% of 22,000=4,40022,000 = 4,400. District C Female Government Workers = 10,500(4,800+4,400)=1,30010,500 - (4,800 + 4,400) = 1,300.
Subtracting District A and B government females from the overall total isolates District C's count.
6
Compute the final ratio
Ratio = 1,30058,000=13580\frac{1,300}{58,000} = \frac{13}{580} or 13:58013 : 580.
Simplifying the fraction gives the required final ratio.

Question 22Question

In a state public infrastructure development scheme for the fiscal year 2025–26, a total budget of ₹9,0009,000 crore was allocated across four major sectors: Agriculture Irrigation, Highway Expansion, Solar Infrastructure, and Rural Electrification.

Agriculture Irrigation received 28%28\% of the total allocated budget. The budget allocated to Highway Expansion was 37.5%37.5\% more than the budget allocated to Agriculture Irrigation. The remaining allocated budget was divided between Solar Infrastructure and Rural Electrification in the ratio 5:45 : 4.

Regarding the actual expenditures recorded at the end of the fiscal year:
- Agriculture Irrigation utilized 85%85\% of its allocated funds.
- Highway Expansion utilized 92%92\% of its allocated funds.
- Solar Infrastructure had an unspent budget of ₹315315 crore.
- Rural Electrification spent an amount equal to 1.251.25 times the unspent budget of Agriculture Irrigation.

Based on the information provided, what is the total unspent budget across all four sectors combined, expressed in crore rupees?

Show answer & explanation

Answer: 1837.7

Answer

The total unspent budget across all four sectors combined is 1837.7 crore rupees.
By accurately deriving each sector's allocation from the given base percentage, percentage increment, and ratio, and then computing the respective unspent components according to the expenditure conditions, the total unspent amount is determined to be 1837.7 crore rupees.

Step-by-Step Solution

1
Calculate allocations for Agriculture Irrigation and Highway Expansion
Agriculture Irrigation = ₹2,520 crore; Highway Expansion = ₹3,465 crore
Agriculture Irrigation receives 28% of 9,000 crore = 2,520 crore. Highway Expansion gets 37.5% more than Agriculture Irrigation, which is 2,520 * (1 + 0.375) = 3,465 crore.
2
Calculate allocations for Solar Infrastructure and Rural Electrification
Solar Infrastructure = ₹1,675 crore; Rural Electrification = ₹1,340 crore
Remaining budget = 9,000 - (2,520 + 3,465) = 3,015 crore. Dividing 3,015 in ratio 5:4 gives (5/9)*3,015 = 1,675 crore for Solar and (4/9)*3,015 = 1,340 crore for Rural Electrification.
3
Determine unspent amounts for each sector individually
Agriculture Irrigation Unspent = ₹378 crore; Highway Expansion Unspent = ₹277.2 crore; Solar Infrastructure Unspent = ₹315 crore; Rural Electrification Unspent = ₹867.5 crore
15% of Agriculture Irrigation budget is unspent = 0.15 * 2,520 = 378 crore. 8% of Highway Expansion budget is unspent = 0.08 * 3,465 = 277.2 crore. Solar unspent is given as 315 crore. Rural Electrification expenditure is 1.25 * 378 = 472.5 crore, leaving 1,340 - 472.5 = 867.5 crore unspent.
4
Sum unspent amounts across all four sectors
Total Unspent Budget = ₹1,837.7 crore
Summing unspent amounts: 378 + 277.2 + 315 + 867.5 = 1,837.7 crore rupees.

Question 25Question

During a public health immunization drive in a rural district, a total of 1,5001,500 vaccines were administered across three primary health centers: PHC Alpha, PHC Beta, and PHC Gamma. PHC Alpha administered 550550 vaccines, while PHC Beta administered 600600 vaccines. The remaining vaccines were administered by PHC Gamma. What is the total number of vaccines administered by PHC Gamma?

Show answer & explanation

Answer: 350350

Answer

The total number of vaccines administered by PHC Gamma is 350350.
The total number of vaccines administered across all three health centers is 1,5001,500. Adding the vaccines administered by PHC Alpha (550550) and PHC Beta (600600) yields a total of 1,1501,150. Subtracting 1,1501,150 from 1,5001,500 gives 350350 vaccines administered by PHC Gamma.

Step-by-Step Solution

1
Calculate the total vaccines administered by PHC Alpha and PHC Beta combined.
550+600=1,150550 + 600 = 1,150 vaccines
To find the remaining amount for PHC Gamma, first aggregate the given counts of the other two health centers.
2
Subtract the combined count from the grand total of vaccines administered.
1,5001,150=3501,500 - 1,150 = 350 vaccines

Question 26Question

A regional energy transition board reviewed the adoption of residential solar panels across three counties: County Alpha, County Beta, and County Gamma. At the beginning of 20252025, there were a total of 4,0004,000 households equipped with solar panels across these three counties. The number of such households in County Alpha was 1,5001,500. At that time, County Beta had 50%50\% more solar-equipped households than County Gamma.

Over the course of 20252025, the number of solar-equipped households in County Alpha increased by 20%20\%, while County Gamma saw a 40%40\% increase. By the end of 20252025, the total number of solar-equipped households across all three counties reached 5,0005,000.

Based on the information provided, which of the following statements are correct?

Select all that apply

Show answer & explanation

Answer: The percentage increase in solar-equipped households in County Beta during 20252025 was 20%20\%.; The ratio of the number of solar-equipped households in County Gamma to County Alpha at the end of 20252025 was 7:97:9.

Answer

The statements confirming that County Beta saw a 20%20\% increase and that the final ratio of County Gamma to County Alpha was 7:97:9 are both correct.
The valid statements accurately reflect that County Beta's solar adoption increased by exactly 300300 households from a base of 1,5001,500 (a 20%20\% rise), and the final counts for County Gamma (1,4001,400) and County Alpha (1,8001,800) produce a ratio of 7:97:9.

Step-by-Step Solution

1
Determine the initial number of solar-equipped households for all three counties at the start of 20252025.
Total = 4,0004,000. Alpha = 1,5001,500. Remaining for Beta and Gamma = 4,0001,500=2,5004,000 - 1,500 = 2,500. Let Gamma = G. Beta is 50%50\% more, so Beta = 1.5G1.5G. Equation: 1.5G+G=2,5002.5G=2,500G=1,0001.5G + G = 2,500 \Rightarrow 2.5G = 2,500 \Rightarrow G = 1,000. Thus, Beta = 1,5001,500.
Establishing the baseline data for each category is necessary before applying growth percentages.
2
Calculate the growth and final number of households for County Alpha and County Gamma.
Alpha increase = 0.20×1,500=3000.20 \times 1,500 = 300, so Alpha final = 1,8001,800. Gamma increase = 0.40×1,000=4000.40 \times 1,000 = 400, so Gamma final = 1,4001,400.
These figures are explicitly given as percentage increases in the text and are required to find the unknown variables.
3
Deduce the final number and percentage increase for County Beta.
Total increase = Final Total - Initial Total = 5,0004,000=1,0005,000 - 4,000 = 1,000. Beta increase = Total increase - (Alpha increase + Gamma increase) = 1,000(300+400)=3001,000 - (300 + 400) = 300. Beta final = 1,500+300=1,8001,500 + 300 = 1,800. Beta percentage increase = (300/1,500)×100%=20%(300 / 1,500) \times 100\% = 20\%.
Using the overall total allows extraction of the missing piece of data through subtraction.
4
Evaluate all provided statements against the extracted data.
County Beta's growth was 20%20\% (True). County Beta's final count was 1,8001,800, not 2,1002,100 (False). Gamma to Alpha final ratio is 1,400:1,800=7:91,400:1,800 = 7:9 (True). Overall total growth is 1,000/4,000=25%1,000 / 4,000 = 25\%, not 20%20\% (False).

Question 28Question

In a state e-governance initiative, a total of 2,4002,400 Common Service Centers (CSCs) are distributed across three districts: District P, District Q, and District R. District P contains 30%30\% of the total CSCs. The ratio of the total number of CSCs in District Q to those in District R is 4:34:3. Each CSC is operated by either a male or a female entrepreneur. In District P, 25%25\% of the CSCs are operated by female entrepreneurs. The number of female-operated CSCs in District Q is 50%50\% more than the number of female-operated CSCs in District P. If the total number of female-operated CSCs across all three districts combined is 600600, what is the ratio of male-operated CSCs in District Q to the female-operated CSCs in District R?

Show answer & explanation

Answer: 23:523:5

Answer

The correct ratio is 23:523:5.
Based on the text, District Q has a total of 960 CSCs and District P has 180 female-operated CSCs. Since District Q has 50% more female-operated CSCs than P, it has 270 female-operated CSCs. This leaves 690 male-operated CSCs in Q. Since the total female-operated CSCs across all districts is 600, District R has 600 - (180 + 270) = 150 female-operated CSCs. The ratio of male-operated CSCs in Q to female-operated CSCs in R is 690:150, which simplifies to 23:5.

Step-by-Step Solution

1
Calculate the total number of CSCs in each district.
District P = 720. District Q = 960. District R = 720.
District P has 30% of 2,400 = 720. The remaining 1,680 CSCs are divided between Q and R in a 4:3 ratio. District Q = (4/7) * 1,680 = 960. District R = (3/7) * 1,680 = 720.
2
Calculate the number of female-operated CSCs in Districts P and Q.
Female in P = 180. Female in Q = 270.
Female CSCs in P = 25% of 720 = 180. Female CSCs in Q is 50% more than in P, meaning 180 + (0.50 * 180) = 180 + 90 = 270.
3
Calculate the number of female-operated CSCs in District R.
Female in R = 150.
Total female CSCs = 600. Female in R = Total - (Female P + Female Q) = 600 - (180 + 270) = 600 - 450 = 150.
4
Calculate the number of male-operated CSCs in District Q.
Male in Q = 690.
Total CSCs in Q (960) - Female in Q (270) = 690.
5
Find the requested ratio.
23:5
Ratio of Male in Q to Female in R = 690 : 150. Dividing both sides by 30 gives 23 : 5.

- The number of aspirants who read ONLY *Business Standard* is 7070.
- The number of aspirants who read ONLY *The Hindu* is equal to the number of aspirants who read ONLY *The Indian Express*.

Based on the data provided, how many aspirants in total do NOT read any of the three newspapers?

Show answer & explanation

Answer: 4545

Answer

The total number of aspirants who do not read any of the three newspapers is 45.
By resolving the 7 disjoint regions of the Venn diagram using the given ratio 3k:2k:4k3k : 2k : 4k, we find k=15k = 15 from the total for Business Standard (180=70+4k+2k+20180 = 70 + 4k + 2k + 20). This yields exclusive intersection values of 4545, 3030, and 6060. Substituting these into the total for Indian Express (210210) yields Only(E)=115\text{Only}(E) = 115, which also equals Only(H)\text{Only}(H). Summing all seven disjoint regions gives 115+115+70+45+30+60+20=455115 + 115 + 70 + 45 + 30 + 60 + 20 = 455. Subtracting from the total population of 500500 gives 4545 aspirants who do not read any of the three newspapers.

Step-by-Step Solution

1
Define disjoint regions of the Venn diagram using given variables.
Let HH, EE, and BB denote the sets of readers. Let Only(HE)=3k\text{Only}(H \cap E) = 3k, Only(EB)=2k\text{Only}(E \cap B) = 2k, and Only(HB)=4k\text{Only}(H \cap B) = 4k. The center intersection All Three=20\text{All Three} = 20.
Setting up explicit variables for mutually exclusive regions allows algebraic representation of total set sizes.
2
Calculate the ratio constant kk using the total for set BB (Business Standard).
B=Only(B)+Only(HB)+Only(EB)+All Three    180=70+4k+2k+20    90=6k    k=15|B| = \text{Only}(B) + \text{Only}(H \cap B) + \text{Only}(E \cap B) + \text{All Three} \implies 180 = 70 + 4k + 2k + 20 \implies 90 = 6k \implies k = 15.
All sub-regions comprising set BB are known except kk, making it possible to solve for kk directly.

Calculate Only(E)\text{Only}(E) and Only(H)\text{Only}(H).
E=Only(E)+45+30+20=210    Only(E)=115|E| = \text{Only}(E) + 45 + 30 + 20 = 210 \implies \text{Only}(E) = 115. Since Only(H)=Only(E)\text{Only}(H) = \text{Only}(E), Only(H)=115\text{Only}(H) = 115.

In a regional administrative office of 8080 officers, 4545 officers completed a training course in Data Analytics, 4040 officers completed a course in Public Policy, and 1515 officers completed both training courses. How many officers completed neither of the two training courses?

Show answer & explanation

Answer: 1010

Answer

10 officers completed neither of the two training courses.
To find the number of officers who completed neither course, calculate the union of the two sets using inclusion-exclusion: n(Data AnalyticsPublic Policy)=45+4015=70n(\text{Data Analytics} \cup \text{Public Policy}) = 45 + 40 - 15 = 70. The number of officers who completed neither course is the complement of this union relative to the total group: 8070=1080 - 70 = 10.

Step-by-Step Solution

1
Identify the given set values and total universe
Total officers n(U)=80n(U) = 80, Data Analytics n(A)=45n(A) = 45, Public Policy n(B)=40n(B) = 40, Both n(AB)=15n(A \cap B) = 15.
Establish baseline data to apply the set inclusion-exclusion principle.
2
Calculate the number of officers who completed at least one training course using the principle of inclusion-exclusion
n(AB)=n(A)+n(B)n(AB)=45+4015=70n(A \cup B) = n(A) + n(B) - n(A \cap B) = 45 + 40 - 15 = 70.
Avoid double-counting the officers who completed both courses.
3
Calculate the number of officers who completed neither course
n(Neither)=n(U)n(AB)=8070=10n(\text{Neither}) = n(U) - n(A \cup B) = 80 - 70 = 10.

Question 31Question

Is the positive integer nn divisible by 3636?

Statement I: n2n^2 is divisible by 108108.
Statement II: n3n^3 is divisible by 576576.

Which of the following options correctly describes the sufficiency of the statements?

Show answer & explanation

Answer: Both Statement I and Statement II together are sufficient to answer the question, but neither statement alone is sufficient.

Answer

Both Statement I and Statement II together are sufficient to answer the question, but neither statement alone is sufficient.
Evaluating both statements together shows that Statement I requires nn to be a multiple of 1818 (21×322^1 \times 3^2) and Statement II requires nn to be a multiple of 1212 (22×312^2 \times 3^1). The least common multiple of 1818 and 1212 is 3636, which proves that nn is guaranteed to be divisible by 3636. Neither statement alone provides both prime factor requirements.

Step-by-Step Solution

1
Analyze Statement I individually
Statement I states that n2n^2 is divisible by 108=22×33108 = 2^2 \times 3^3. In the prime factorization of a square n2n^2, all exponents must be even numbers. Thus, n2n^2 must contain at least 222^2 and 343^4. Taking square roots, nn must be a multiple of 21×32=182^1 \times 3^2 = 18. If n=18n = 18, nn is NOT divisible by 3636. If n=36n = 36, nn IS divisible by 3636. Because we get both 'No' and 'Yes' answers, Statement I alone is NOT sufficient.
We must test if Statement I uniquely determines whether nn is divisible by 3636.
2
Analyze Statement II individually
Statement II states that n3n^3 is divisible by 576=26×32576 = 2^6 \times 3^2. In the prime factorization of a cube n3n^3, all exponents must be multiples of 33. Thus, n3n^3 must contain at least 262^6 and 333^3. Taking cube roots, nn must be a multiple of 22×31=122^2 \times 3^1 = 12. If n=12n = 12, nn is NOT divisible by 3636. If n=36n = 36, nn IS divisible by 3636. Because we get both 'No' and 'Yes' answers, Statement II alone is NOT sufficient.
We must test if Statement II uniquely determines whether nn is divisible by 3636.
3
Combine Statement I and Statement II
From Statement I, nn contains at least 323^2 in its prime factorization. From Statement II, nn contains at least 222^2 in its prime factorization. Combining these requirements, nn must contain at least 22×32=362^2 \times 3^2 = 36. Therefore, nn is guaranteed to be divisible by 3636. Both statements together yield a definitive 'Yes'.
Evaluating both statements together combines the minimal necessary powers of each prime factor.

Question 34Question

The following missing data table presents the annual cargo volume (in Thousand Metric Tonnes, TMT) handled across three terminals (Terminal A, Terminal B, and Terminal C) at a major seaport for three distinct cargo categories: Bulk Cargo, Liquid Cargo, and Containerized Cargo.

TerminalBulk CargoLiquid CargoContainerized CargoTotal
Terminal A120150450
Terminal B210180500
Terminal C160140420
Total3905304501370

Based on the table above, what is the volume of Liquid Cargo (in Thousand Metric Tonnes) handled by Terminal A?

Show answer & explanation

Answer: 180

Answer

The volume of Liquid Cargo handled by Terminal A is 180 Thousand Metric Tonnes.
The row total for Terminal A is 450 TMT450\text{ TMT}. The known components are Bulk Cargo (120 TMT120\text{ TMT}) and Containerized Cargo (150 TMT150\text{ TMT}). Subtracting these from the total yields 450(120+150)=180 TMT450 - (120 + 150) = 180\text{ TMT}. Alternatively, using the column total for Liquid Cargo (530 TMT530\text{ TMT}) minus the Liquid Cargo of Terminal B (210 TMT210\text{ TMT}) and Terminal C (140 TMT140\text{ TMT}) gives 530350=180 TMT530 - 350 = 180\text{ TMT}.

Step-by-Step Solution

1
Examine the row for Terminal A to find total cargo and known cargo types
Total cargo for Terminal A = 450 TMT450\text{ TMT}, Bulk Cargo = 120 TMT120\text{ TMT}, Containerized Cargo = 150 TMT150\text{ TMT}.
The sum of all cargo categories for a terminal equals the row total.
2
Calculate the sum of known cargo categories for Terminal A
120+150=270 TMT120 + 150 = 270\text{ TMT}.
Combining known entries simplifies finding the unknown value.
3
Subtract the sum of known categories from the row total
450270=180 TMT450 - 270 = 180\text{ TMT}.
Liquid Cargo for Terminal A is the remaining portion of its total cargo volume.
4
Cross-verify using the column total for Liquid Cargo
Total Liquid Cargo = 530 TMT530\text{ TMT}. Liquid Cargo for Terminal B = 210 TMT210\text{ TMT} and Terminal C = 140 TMT140\text{ TMT}. Terminal A Liquid Cargo = 530(210+140)=530350=180 TMT530 - (210 + 140) = 530 - 350 = 180\text{ TMT}.
Cross-verification confirms numerical consistency.

Question 35Question

The table below presents the operational metrics for Agricultural Processing Units across four districts of a state for FY 2025–26:

DistrictTotal Processing Capacity (in '000 MT)Operational Units CountTotal Raw Produce Received (in '000 MT)Processing Efficiency Rate (%)
District A4501836085%85\%
District B6002448090%90\%
District C5002042080%80\%
District D3501432075%75\%

*Note: Processing Efficiency Rate is defined as the percentage of Total Raw Produce Received that is converted into finished products. The remaining portion of received raw produce is lost as processing waste.*

What is the overall average processing waste (in '000 Metric Tonnes) per operational unit across all four districts combined?

Show answer & explanation

Answer: 3.5

Answer

The overall average processing waste per operational unit across all four districts combined is 3.53.5 thousand Metric Tonnes.
The correct answer is derived by first finding the waste volume for each district based on raw produce received: District A (360×0.15=54360 \times 0.15 = 54), District B (480×0.10=48480 \times 0.10 = 48), District C (420×0.20=84420 \times 0.20 = 84), and District D (320×0.25=80320 \times 0.25 = 80). Summing these gives a combined total waste of 266266 thousand MT. Dividing this total waste by the total count of operational units (18+24+20+14=7618 + 24 + 20 + 14 = 76) yields 26676=3.5\frac{266}{76} = 3.5 thousand MT per unit.

Step-by-Step Solution

1
Calculate the processing waste percentage for each district
District A waste rate = 100%85%=15%100\% - 85\% = 15\%; District B waste rate = 100%90%=10%100\% - 90\% = 10\%; District C waste rate = 100%80%=20%100\% - 80\% = 20\%; District D waste rate = 100%75%=25%100\% - 75\% = 25\%.
Processing waste is the complement of processing efficiency rate.
2
Calculate total processing waste generated in each district in '000 MT
District A waste = 360×0.15=54360 \times 0.15 = 54 '000 MT; District B waste = 480×0.10=48480 \times 0.10 = 48 '000 MT; District C waste = 420×0.20=84420 \times 0.20 = 84 '000 MT; District D waste = 320×0.25=80320 \times 0.25 = 80 '000 MT.
Absolute waste is obtained by multiplying Total Raw Produce Received by the waste rate.
3
Calculate total waste and total operational units across all four districts combined
Total Waste = 54+48+84+80=26654 + 48 + 84 + 80 = 266 '000 MT. Total Operational Units = 18+24+20+14=7618 + 24 + 20 + 14 = 76 units.
Aggregating metrics across districts is required to find the combined weighted average.
4
Divide total combined waste by total combined operational units
Average Waste per Unit = 26676=3.5\frac{266}{76} = 3.5 '000 MT per unit.
Overall average metric equals total aggregate waste divided by total aggregate count of units.

Statement I: The train takes 20 seconds20\text{ seconds} to completely cross the platform.
Statement II: The train takes 8 seconds8\text{ seconds} to cross a telegraph pole standing beside the track.

Which of the following options correctly describes the sufficiency of the statements to answer the question?

Show answer & explanation

Answer: Both Statement I and Statement II together are necessary and sufficient to answer the question.

Answer

Both Statement I and Statement II together are necessary and sufficient to answer the question.
Evaluating each statement individually shows that neither Statement I nor Statement II alone provides enough information to determine the speed of the train because the length of the train remains unknown. However, combining both statements yields a system of two independent linear equations with two variables (length and speed of the train), allowing us to solve uniquely for the speed of the train (60 km/h60\text{ km/h}). Therefore, both statements together are necessary and sufficient.

Step-by-Step Solution

1
Analyze Statement I alone.
Let the length of the train be L metersL\text{ meters} and its speed be v m/sv\text{ m/s}. The equation is L+200=20vL + 200 = 20v. Since there are two unknowns (LL and vv), Statement I alone is not sufficient.
The length of the train is an unknown variable.
2
Analyze Statement II alone.
Crossing a telegraph pole means distance traveled equals the length of the train. The equation is L=8vL = 8v. Since there are two unknowns (LL and vv), Statement II alone is not sufficient.
The speed cannot be determined without knowing the length of the train.
3
Evaluate Statement I and Statement II together.
Substitute L=8vL = 8v into the first equation: 8v+200=20v    12v=200    v=503 m/s8v + 200 = 20v \implies 12v = 200 \implies v = \frac{50}{3}\text{ m/s}. Converting to km/h\text{km/h}: v=503×185=60 km/hv = \frac{50}{3} \times \frac{18}{5} = 60\text{ km/h}. Thus, both statements together give a unique answer.
Two independent equations are sufficient to solve for two unknown variables.

Question 37Question

In a state public health drive conducted across three administrative zones—Zone X, Zone Y, and Zone Z—a total of 12,00012,000 vaccines were administered. Zone X received 35%35\% of the total vaccines administered. In Zone Y, the total number of vaccines administered was 800800 more than that in Zone X, and the ratio of vaccines administered to children versus adults was 2:32 : 3. The remaining vaccines were administered in Zone Z, where 60%60\% of the recipients were adults and the rest were children. If 40%40\% of the recipients in Zone X were children, what is the total number of children who received vaccines across all three zones combined?

Show answer & explanation

Answer: 4,8004,800

Answer

4,8004,800 children received vaccines across all three zones combined.
The total vaccines administered across the three zones equal 12,00012,000. Zone X accounts for 35%35\% (4,2004,200 vaccines), of which 40%40\% are children (1,6801,680). Zone Y receives 800800 more than Zone X (5,0005,000 vaccines), with children making up 2/52/5 of this amount (2,0002,000). Zone Z receives the remaining 2,8002,800 vaccines, where 40%40\% are children (1,1201,120). Adding these together (1,680+2,000+1,1201,680 + 2,000 + 1,120) yields 4,8004,800.

Step-by-Step Solution

1
Calculate total vaccines and child recipients in Zone X
Total in Zone X = 0.35×12,000=4,2000.35 \times 12,000 = 4,200. Children in Zone X = 0.40×4,200=1,6800.40 \times 4,200 = 1,680.
Zone X receives 35%35\% of total vaccines, and 40%40\% of Zone X recipients are children.
2
Calculate total vaccines and child recipients in Zone Y
Total in Zone Y = 4,200+800=5,0004,200 + 800 = 5,000. Children in Zone Y = 22+3×5,000=25×5,000=2,000\frac{2}{2 + 3} \times 5,000 = \frac{2}{5} \times 5,000 = 2,000.
Zone Y receives 800800 more vaccines than Zone X, and children make up 22 parts out of 55 total parts.
3
Calculate total vaccines and child recipients in Zone Z
Total in Zone Z = 12,000(4,200+5,000)=2,80012,000 - (4,200 + 5,000) = 2,800. Children percentage in Zone Z = 100%60%=40%100\% - 60\% = 40\%. Children in Zone Z = 0.40×2,800=1,1200.40 \times 2,800 = 1,120.
Zone Z receives the remainder of total vaccines, and children constitute the remaining 40%40\% of Zone Z recipients.
4
Sum child recipients across all three zones
Total children = 1,680+2,000+1,120=4,8001,680 + 2,000 + 1,120 = 4,800.
Adding the child counts from Zone X, Zone Y, and Zone Z yields the final combined total.

In a state disaster relief operation, a total of 1,2001,200 food packets were distributed among three relief camps: Camp A, Camp B, and Camp C. Camp A received 400400 packets, while Camp B received 150150 more packets than Camp A. The remaining food packets were distributed to Camp C. How many food packets were distributed to Camp C?

Show answer & explanation

Answer: 250

Answer

The total number of food packets distributed to Camp C is 250.
Camp A receives 400 packets. Camp B receives 150 more than Camp A, which equals 400 + 150 = 550 packets. Combined, Camp A and Camp B receive 400 + 550 = 950 packets. Subtracting 950 from the total allocation of 1,200 packets leaves 250 packets for Camp C.

Step-by-Step Solution

1
Identify the number of packets given to Camp A and calculate the packets given to Camp B.
Camp A = 400 packets; Camp B = 400 + 150 = 550 packets.
The paragraph states Camp B received 150 more packets than Camp A.
2
Calculate the total number of packets distributed to Camp A and Camp B together.
Total for Camp A and Camp B = 400 + 550 = 950 packets.
Adding the individual allocations of Camp A and Camp B.
3
Subtract the combined allocation of Camp A and Camp B from the overall total packets.
Camp C = 1200 - 950 = 250 packets.
The remaining packets out of the total 1,200 were given to Camp C.

Statement II: Partner AA's share of the annual profit is $2,400\$2,400.

Which of the following options correctly describes the sufficiency of the statements to answer the question?

Show answer & explanation

Answer: Both Statement I and Statement II together are sufficient to answer the question, but neither statement alone is sufficient.

Answer

Both Statement I and Statement II together are sufficient to answer the question, but neither statement alone is sufficient.
Evaluating Statement I alone gives the profit-sharing ratio between Partner A and Partner B as (6000×12):(9000×8)=1:1(6000 \times 12) : (9000 \times 8) = 1 : 1, which is insufficient by itself to find the monetary profit. Statement II alone gives Partner A's profit share as $2,400\$2,400, which is also insufficient without knowing the proportion. Combining both statements shows that both partners receive equal shares, so total profit is $2,400×2=$4,800\$2,400 \times 2 = \$4,800. Therefore, both statements together are necessary and sufficient.

Step-by-Step Solution

1
Evaluate Statement I alone
Profit sharing ratio of A to B = (6000×12):(9000×8)=72,000:72,000=1:1(6000 \times 12) : (9000 \times 8) = 72,000 : 72,000 = 1 : 1.
Profit is distributed in proportion to the product of capital invested and time period. Since no dollar amounts of profit are given, total profit cannot be determined from Statement I alone.
2
Evaluate Statement II alone
Partner A's profit share = $2,400\$2,400.
Without knowing Partner B's share or the ratio between their shares, the total profit cannot be calculated from Statement II alone.
3
Evaluate Statement I and Statement II together
Since ratio of shares is 1:11:1 and A's share is $2,400\$2,400, B's share is also $2,400\$2,400. Total profit = $2,400+$2,400=$4,800\$2,400 + \$2,400 = \$4,800.
Combining the ratio from Statement I and the monetary value from Statement II gives a unique answer to the question.

Answer: The total rooftop solar capacity installed across all three districts is 6,900 kW6,900\text{ kW}.; The ground-mounted solar capacity in District Gamma is exactly twice its rooftop solar capacity.; The ratio of total ground-mounted solar capacity to total rooftop solar capacity across all three districts is 27:2327 : 23.

Answer

The statements confirming that total rooftop solar capacity is 6,900 kW6,900\text{ kW}, ground-mounted capacity in District Gamma is twice its rooftop capacity, and the ratio of total ground-mounted to rooftop capacity is 27:2327 : 23 are all correct.
Evaluating the data step by step shows that District Alpha has 3,600 kW3,600\text{ kW} rooftop and 2,400 kW2,400\text{ kW} ground-mounted capacity; District Beta has 1,800 kW1,800\text{ kW} rooftop and 2,700 kW2,700\text{ kW} ground-mounted capacity; District Gamma has 1,500 kW1,500\text{ kW} rooftop and 3,000 kW3,000\text{ kW} ground-mounted capacity. This confirms that total rooftop capacity is 6,900 kW6,900\text{ kW}, District Gamma's ground-mounted capacity is twice its rooftop capacity (3,000 kW=2×1,500 kW3,000\text{ kW} = 2 \times 1,500\text{ kW}), and the overall ratio of ground-mounted to rooftop capacity is 8,100:6,900=27:238,100 : 6,900 = 27 : 23.

Step-by-Step Solution

1
Calculate total capacity allocation for each district.
Alpha = 40% of 15,000=6,000 kW40\% \text{ of } 15,000 = 6,000\text{ kW}. Beta = 34×6,000=4,500 kW\frac{3}{4} \times 6,000 = 4,500\text{ kW}. Gamma = 15,000(6,000+4,500)=4,500 kW15,000 - (6,000 + 4,500) = 4,500\text{ kW}.
Determining individual district totals is necessary to break down capacity by panel type.
2
Determine rooftop and ground-mounted capacities for District Alpha and District Beta.
District Alpha: Rooftop = 60% of 6,000=3,600 kW60\% \text{ of } 6,000 = 3,600\text{ kW}, Ground = 2,400 kW2,400\text{ kW}. District Beta: Ratio 2:3    2:3 \implies Rooftop = 25×4,500=1,800 kW\frac{2}{5} \times 4,500 = 1,800\text{ kW}, Ground = 35×4,500=2,700 kW\frac{3}{5} \times 4,500 = 2,700\text{ kW}.
Applying given percentages and ratios yields the exact breakdown for Alpha and Beta.
3
Determine rooftop and ground-mounted capacities for District Gamma.
Let Rooftop = RR and Ground = GG. We have G+R=4,500G + R = 4,500 and GR=1,500G - R = 1,500. Solving gives 2G=6,000    G=3,000 kW2G = 6,000 \implies G = 3,000\text{ kW} and R=1,500 kWR = 1,500\text{ kW}.
Setting up simultaneous equations resolves the unknown components for Gamma.
4
Verify overall totals and evaluate each statement.
Total Rooftop = 3,600+1,800+1,500=6,900 kW3,600 + 1,800 + 1,500 = 6,900\text{ kW}. Total Ground = 2,400+2,700+3,000=8,100 kW2,400 + 2,700 + 3,000 = 8,100\text{ kW}. Gamma Ground/Rooftop ratio = 3,000/1,500=23,000 / 1,500 = 2. Beta percentage of total = 4,500/15,000=30%4,500 / 15,000 = 30\%. Ground to Rooftop ratio = 8,100/6,900=27/238,100 / 6,900 = 27 / 23.
Direct comparison evaluates which statements are factually supported by the paragraph data.
