Cevap: $13 : 580$

Cevap

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 : 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.

Adım Adım Çözüm

1

Calculate total workforce and gender breakdown for District A

Total workforce of District A =

40\%

of

100,000 = 40,000

. With a Male:Female ratio of

3:2

, Male workforce =

\frac{3}{5} \times 40,000 = 24,000

and Female workforce =

\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 \times 40,000 = 50,000

. Female workforce =

44\%

of

50,000 = 22,000

. Male workforce =

50,000 - 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) = 10,000

. With Male:Female ratio of

3:2

, Male workforce =

\frac{3}{5} \times 10,000 = 6,000

and Female workforce =

\frac{2}{5} \times 10,000 = 4,000

.

District C contains the residual workforce from the total

100,000

.

4

Calculate overall male and female workforce totals

Total Male workforce =

24,000 + 28,000 + 6,000 = 58,000

. Total Female workforce =

16,000 + 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\%

of

42,000 = 10,500

. District A Female Government Workers =

30\%

of

16,000 = 4,800

. District B Female Government Workers =

20\%

of

22,000 = 4,400

. District C Female Government Workers =

10,500 - (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 =

\frac{1,300}{58,000} = \frac{13}{580}

or

13 : 580

.

Simplifying the fraction gives the required final ratio.

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

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

Regarding the actual expenditures recorded at the end of the fiscal year:
- Agriculture Irrigation utilized $85\%$ of its allocated funds.
- Highway Expansion utilized $92\%$ of its allocated funds.
- Solar Infrastructure had an unspent budget of ₹ $315$ crore.
- Rural Electrification spent an amount equal to $1.25$ 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?

Cevabı ve açıklamayı göster

Cevap: 1837.7

Cevap

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.

Adım Adım Çözüm

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.

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.

Adım Adım Çözüm

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.

Cevap: $45$

Cevap

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 : 4k

, we find

k = 15

from the total for Business Standard (

180 = 70 + 4k + 2k + 20

). This yields exclusive intersection values of

45

,

30

, and

60

. Substituting these into the total for Indian Express (

210

) yields

\text{Only}(E) = 115

, which also equals

\text{Only}(H)

. Summing all seven disjoint regions gives

115 + 115 + 70 + 45 + 30 + 60 + 20 = 455

. Subtracting from the total population of

500

gives

45

aspirants who do not read any of the three newspapers.

Adım Adım Çözüm

1

Define disjoint regions of the Venn diagram using given variables.

Let

H

,

E

, and

B

denote the sets of readers. Let

\text{Only}(H \cap E) = 3k

,

\text{Only}(E \cap B) = 2k

, and

\text{Only}(H \cap B) = 4k

. The center intersection

\text{All Three} = 20

.

Setting up explicit variables for mutually exclusive regions allows algebraic representation of total set sizes.

2

Calculate the ratio constant

k

using the total for set

B

(Business Standard).

|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

B

are known except

k

, making it possible to solve for

k

directly.

3

Determine the exact counts of two-set exclusive intersections.

\text{Only}(H \cap E) = 3(15) = 45

,

\text{Only}(E \cap B) = 2(15) = 30

, and

\text{Only}(H \cap B) = 4(15) = 60

.

Multiplying the ratio multipliers by

k = 15

gives exact counts for each overlap.

4

Calculate

\text{Only}(E)

and

\text{Only}(H)

.

|E| = \text{Only}(E) + 45 + 30 + 20 = 210 \implies \text{Only}(E) = 115

. Since

\text{Only}(H) = \text{Only}(E)

,

\text{Only}(H) = 115

.

Subtracting known intersection counts of set

E

from

|E| = 210

gives

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

Cevap

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

n

to be a multiple of

18

(

2^1 \times 3^2

) and Statement II requires

n

to be a multiple of

12

(

2^2 \times 3^1

). The least common multiple of

18

and

12

is

36

, which proves that

n

is guaranteed to be divisible by

36

. Neither statement alone provides both prime factor requirements.

Adım Adım Çözüm

1

Analyze Statement I individually

Statement I states that

n^2

is divisible by

108 = 2^2 \times 3^3

. In the prime factorization of a square

n^2

, all exponents must be even numbers. Thus,

n^2

must contain at least

2^2

and

3^4

. Taking square roots,

n

must be a multiple of

2^1 \times 3^2 = 18

. If

n = 18

,

n

is NOT divisible by

36

. If

n = 36

,

n

IS divisible by

36

. Because we get both 'No' and 'Yes' answers, Statement I alone is NOT sufficient.

We must test if Statement I uniquely determines whether

n

is divisible by

36

.

2

Analyze Statement II individually

Statement II states that

n^3

is divisible by

576 = 2^6 \times 3^2

. In the prime factorization of a cube

n^3

, all exponents must be multiples of

3

. Thus,

n^3

must contain at least

2^6

and

3^3

. Taking cube roots,

n

must be a multiple of

2^2 \times 3^1 = 12

. If

n = 12

,

n

is NOT divisible by

36

. If

n = 36

,

n

IS divisible by

36

. Because we get both 'No' and 'Yes' answers, Statement II alone is NOT sufficient.

We must test if Statement II uniquely determines whether

n

is divisible by

36

.

3

Combine Statement I and Statement II

From Statement I,

n

contains at least

3^2

in its prime factorization. From Statement II,

n

contains at least

2^2

in its prime factorization. Combining these requirements,

n

must contain at least

2^2 \times 3^2 = 36

. Therefore,

n

is guaranteed to be divisible by

36

. Both statements together yield a definitive 'Yes'.

Evaluating both statements together combines the minimal necessary powers of each prime factor.

Terminal A	120	—	150	450
Terminal B	—	210	180	500
Terminal C	160	140	—	420

Cevap: 180

Cevap

The volume of Liquid Cargo handled by Terminal A is 180 Thousand Metric Tonnes.

The row total for Terminal A is

450\text{ TMT}

. The known components are Bulk Cargo (

120\text{ TMT}

) and Containerized Cargo (

150\text{ TMT}

). Subtracting these from the total yields

450 - (120 + 150) = 180\text{ TMT}

. Alternatively, using the column total for Liquid Cargo (

530\text{ TMT}

) minus the Liquid Cargo of Terminal B (

210\text{ TMT}

) and Terminal C (

140\text{ TMT}

) gives

530 - 350 = 180\text{ TMT}

.

Adım Adım Çözüm

1

Examine the row for Terminal A to find total cargo and known cargo types

Total cargo for Terminal A =

450\text{ TMT}

, Bulk Cargo =

120\text{ TMT}

, Containerized Cargo =

150\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\text{ TMT}

.

Combining known entries simplifies finding the unknown value.

3

Subtract the sum of known categories from the row total

450 - 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\text{ TMT}

. Liquid Cargo for Terminal B =

210\text{ TMT}

and Terminal C =

140\text{ TMT}

. Terminal A Liquid Cargo =

530 - (210 + 140) = 530 - 350 = 180\text{ TMT}

*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?

Cevabı ve açıklamayı göster

Cevap: 3.5

Cevap

The overall average processing waste per operational unit across all four districts combined is

3.5

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 \times 0.15 = 54

), District B (

480 \times 0.10 = 48

), District C (

420 \times 0.20 = 84

), and District D (

320 \times 0.25 = 80

). Summing these gives a combined total waste of

266

thousand MT. Dividing this total waste by the total count of operational units (

18 + 24 + 20 + 14 = 76

) yields

\frac{266}{76} = 3.5

thousand MT per unit.

Adım Adım Çözüm

1

Calculate the processing waste percentage for each district

District A waste rate =

100\% - 85\% = 15\%

; District B waste rate =

100\% - 90\% = 10\%

; District C waste rate =

100\% - 80\% = 20\%

; District D waste rate =

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 \times 0.15 = 54

'000 MT; District B waste =

480 \times 0.10 = 48

'000 MT; District C waste =

420 \times 0.20 = 84

'000 MT; District D waste =

320 \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 = 266

'000 MT. Total Operational Units =

18 + 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 =

\frac{266}{76} = 3.5

'000 MT per unit.

Overall average metric equals total aggregate waste divided by total aggregate count of units.

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

Cevap

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\text{ km/h}

). Therefore, both statements together are necessary and sufficient.

Adım Adım Çözüm

1

Analyze Statement I alone.

Let the length of the train be

L\text{ meters}

and its speed be

v\text{ m/s}

. The equation is

L + 200 = 20v

. Since there are two unknowns (

L

and

v

), 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 = 8v

. Since there are two unknowns (

L

and

v

), 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 = 8v

into the first equation:

8v + 200 = 20v \implies 12v = 200 \implies v = \frac{50}{3}\text{ m/s}

. Converting to

\text{km/h}

:

v = \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.

Adım Adım Çözüm

1

Evaluate Statement I alone

Profit sharing ratio of A to B =

(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

.

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

1:1

and A's share is

\$2,400

, B's share is also

\$2,400

ground-mounted capacity; District Beta has

1,800\text{ kW}

rooftop and

2,700\text{ kW}

ground-mounted capacity; District Gamma has

1,500\text{ kW}

rooftop and

3,000\text{ kW}

ground-mounted capacity. This confirms that total rooftop capacity is

6,900\text{ kW}

, District Gamma's ground-mounted capacity is twice its rooftop capacity (

3,000\text{ kW} = 2 \times 1,500\text{ kW}

), and the overall ratio of ground-mounted to rooftop capacity is

8,100 : 6,900 = 27 : 23

.

Adım Adım Çözüm

1

Calculate total capacity allocation for each district.

Alpha =

40\% \text{ of } 15,000 = 6,000\text{ kW}

. Beta =

\frac{3}{4} \times 6,000 = 4,500\text{ kW}

. Gamma =

15,000 - (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\% \text{ of } 6,000 = 3,600\text{ kW}

, Ground =

2,400\text{ kW}

. District Beta: Ratio

2:3 \implies

Rooftop =

\frac{2}{5} \times 4,500 = 1,800\text{ kW}

, Ground =

\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 =

R

and Ground =

G

. We have

G + R = 4,500

and

G - R = 1,500

. Solving gives

2G = 6,000 \implies G = 3,000\text{ kW}

and

R = 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\text{ kW}

. Total Ground =

2,400 + 2,700 + 3,000 = 8,100\text{ kW}

. Gamma Ground/Rooftop ratio =

3,000 / 1,500 = 2

. Beta percentage of total =

4,500 / 15,000 = 30\%

. Ground to Rooftop ratio =

8,100 / 6,900 = 27 / 23

.

Direct comparison evaluates which statements are factually supported by the paragraph data.
