A vessel contains a mixture of milk and water. What is the initial total volume of the mixture in the vessel?

Statement I: The initial ratio of milk to water in the vessel is $3:2$ . When $10\text{ liters}$ of water is added to the mixture, the ratio of milk to water becomes $1:1$ .
Statement II: If $15\text{ liters}$ of the original mixture is removed and replaced with $15\text{ liters}$ of pure water, the quantity of milk remaining in the vessel is $27\text{ liters}$ .

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

Statement I alone is sufficient, but Statement II alone is not sufficient.

Statement II alone is sufficient, but Statement I alone is not sufficient.

Either Statement I alone or Statement II alone is sufficient.

Neither Statement I nor Statement II is sufficient.

Both Statement I and Statement II together are sufficient, but neither statement alone is sufficient.

Cevap: Statement I alone is sufficient, but Statement II alone is not sufficient.

Cevap

Statement I alone is sufficient to answer the question, but Statement II alone is not sufficient.

Statement I alone gives a complete quantitative relationship: with initial quantities

3x

and

2x

, adding

10\text{ liters}

of water leads to

3x = 2x + 10

, yielding

x = 10

and a unique total initial volume of

50\text{ liters}

. Statement II alone leaves two unknown variables (initial milk fraction and total volume), so it is not sufficient.

Adım Adım Çözüm

1

Evaluate Statement I alone.

Initial volume is calculated as

50\text{ liters}

.

Let the initial volume of milk be

3x

liters and water be

2x

liters, making the total initial volume

5x

liters. Adding

10\text{ liters}

of water gives the equation

\frac{3x}{2x + 10} = \frac{1}{1}

, which simplifies to

3x = 2x + 10 \implies x = 10

. Thus, total initial volume

5x = 50\text{ liters}

. Hence, Statement I alone is sufficient.

2

Evaluate Statement II alone.

Insufficient to find total initial volume.

Let the total initial volume be

V

liters and the fraction of milk in the initial mixture be

f

. Removing

15\text{ liters}

of mixture removes

15f

liters of milk. Replacing it with water adds no milk. The remaining milk equation is

f(V - 15) = 27

. Since both

f

and

V

are unknown,

V

cannot be uniquely determined. Hence, Statement II alone is not sufficient.

What is the exact value of the two-digit positive integer $N$ ?

Statement (I): The sum of the tens digit and the units digit of $N$ is equal to $12$ .
Statement (II): Reversing the digits of $N$ yields a new two-digit integer that is $36$ greater than $N$ .

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

Statement (I) alone is sufficient, but Statement (II) alone is not sufficient.

Statement (II) alone is sufficient, but Statement (I) alone is not sufficient.

Either Statement (I) alone or Statement (II) alone is sufficient.

Neither Statement (I) nor Statement (II) is sufficient.

Both Statement (I) and Statement (II) together are sufficient, but neither statement alone is sufficient.

Cevap: Both Statement (I) and Statement (II) together are sufficient, 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 each statement independently reveals that neither statement alone narrows

N

down to a single value. Combining both equations (

x + y = 12

and

y - x = 4

) yields a single unique pair

x = 4

and

y = 8

, giving

N = 48

. Therefore, both statements together are required and sufficient.

Adım Adım Çözüm

1

Represent the two-digit integer algebraically.

Let

N = 10x + y

, where

x

is the tens digit (

1 \leq x \leq 9

) and

y

is the units digit (

0 \leq y \leq 9

).

Setting up standard place-value variables allows formal analysis of both statements.

2

Evaluate Statement (I) alone.

From Statement (I),

x + y = 12

. Possible pairs

(x,y)

are

(3,9), (4,8), (5,7), (6,6), (7,5), (8,4), (9,3)

. Thus,

N

could be

39, 48, 57, 66, 75, 84,

or

93

.

Since multiple valid values of

N

exist, Statement (I) alone is NOT sufficient.

3

Evaluate Statement (II) alone.

The reversed number is

10y + x

. Given

(10y + x) - (10x + y) = 36 \implies 9(y - x) = 36 \implies y - x = 4

. Possible pairs

(x,y)

are

(1,5), (2,6), (3,7), (4,8), (5,9)

, giving

N = 15, 26, 37, 48,

or

59

.

Since multiple valid values of

N

exist, Statement (II) alone is NOT sufficient.

4

Evaluate Statement (I) and Statement (II) together.

System of linear equations:

x + y = 12

and

y - x = 4

. Adding the two equations gives

2y = 16 \implies y = 8

. Substituting

y = 8

gives

x = 4

. Thus,

N = 48

uniquely.

Both statements combined provide a unique value for

N

, making them together sufficient.

If the total number of certified candidates across all three sectors combined was $2,898$ , what percentage of the enrolled candidates in the Textile & Apparel sector successfully obtained certification?

Cevabı ve açıklamayı göster

Cevap: 55

Cevap

The certification percentage of enrolled candidates in the Textile & Apparel sector is

55\%

.

To find the certification percentage for the Textile & Apparel sector, first determine the enrollment figures: IT & Electronics has

1,800

candidates (

40\%

of

4,500

), leaving

2,700

candidates split in a

7 : 8

certified (

65\%

of

1,800

), and Healthcare has

936

certified (

80\%

of

1,170

). Subtracting these from the total

2,898

certified candidates leaves

792

certified candidates in Textile & Apparel. Finally,

Is the integer $x$ odd?

Which of the following options is correct?

Statement (I) alone is sufficient, but Statement (II) alone is not sufficient.

Statement (II) alone is sufficient, but Statement (I) alone is not sufficient.

Either Statement (I) alone or Statement (II) alone is sufficient.

Neither Statement (I) nor Statement (II) is sufficient.

Both Statement (I) and Statement (II) together are sufficient, but neither statement alone is sufficient.

Cevabı ve açıklamayı göster

Cevap: Statement (II) alone is sufficient, but Statement (I) alone is not sufficient.

Cevap

Statement (II) alone is sufficient, but Statement (I) alone is not sufficient.

Evaluating Statement (I):

x^2 + 3x = x(x+3)

. The product of any integer

x

and

(x+3)

is always even because one of the two numbers is always even. Thus, Statement (I) provides no specific information about whether

x

is odd or even, making it insufficient. Evaluating Statement (II):

x + 5 = \text{even}

. Subtracting the odd integer

5

from an even integer yields an odd integer, so

x

must be odd. Hence, Statement (II) alone is sufficient to answer the question definitively.

Adım Adım Çözüm

1

Evaluate Statement (I) individually.

Rewrite the expression as

x^2 + 3x = x(x + 3)

. If

x

is even, then

x(x + 3) = \text{even} \times \text{odd} = \text{even}

. If

x

is odd, then

x(x + 3) = \text{odd} \times \text{even} = \text{even}

. Thus,

x^2 + 3x

is always even regardless of whether

x

is odd or even.

Since the statement holds true for all integers

x

, it cannot determine whether

x

is odd. Therefore, Statement (I) alone is NOT sufficient.

2

Evaluate Statement (II) individually.

The statement gives that

x + 5

is an even integer. Since

5

is an odd integer,

\text{Odd} + \text{Odd} = \text{Even}

, which implies

x

must be an odd integer.

This yields a definitive 'Yes' answer to the question 'Is

x

odd?'. Therefore, Statement (II) alone IS sufficient.

3

Conclude the data sufficiency evaluation.

Statement (II) alone is sufficient to answer the question, but Statement (I) alone is not sufficient.

Each statement was evaluated independently first, rendering statement combination unnecessary.

Cevabı ve açıklamayı göster

Cevap: 14 : 25

Cevap

The ratio of energy distributed to the commercial sector by the Southern Grid to the combined commercial distribution of the Northern and Western Grids is 14 : 25.

The correct option stating '14 : 25' accurately follows the prescribed two-stage deduction process. For the Southern Grid, subtracting 12% loss (

1,800\text{ GWh}

) from

15,000\text{ GWh}

gives

13,200\text{ GWh}

, and subtracting

400\text{ GWh}

auxiliary consumption leaves

12,800\text{ GWh}

. Applying

35\%

yields

4,480\text{ GWh}

. For the Northern Grid, net energy is

(12,000 - 1,800) - 200 = 10,000\text{ GWh}

, giving

40\% \times 10,000 = 4,000\text{ GWh}

. For the Western Grid, net energy is

(18,000 - 1,800) - 200 = 16,000\text{ GWh}

, giving

25\% \times 16,000 = 4,000\text{ GWh}

. Combining Northern and Western gives

Cevap

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

Evaluating Statement (I) alone gives only the individual performance of Pipe P, which is insufficient to determine the combined time. Statement (II) alone provides only a relative ratio between the rates of Pipe P and Pipe Q without any concrete time metric, making it insufficient on its own. When both statements are combined, Statement (I) provides the base rate for Pipe P and Statement (II) allows calculation of Pipe Q's rate, leading to a unique answer of 6 hours for the combined operation.

Cevap: ₹72.15 crore

Cevap

₹72.15 crore

To find the total rail transshipment revenue, compute the rail-moved tonnage for each terminal: North (1.80 lakh tonnes), South (3.90 lakh tonnes), East (1.75 lakh tonnes), and West (1.50 lakh tonnes). Multiplying each by its respective revenue per tonne yields ₹14.40 crore, ₹29.25 crore, ₹15.75 crore, and ₹12.75 crore. Summing these four values gives exactly ₹72.15 crore.

Adım Adım Çözüm

1

Convert cargo volumes from thousand metric tonnes to tonnes for each terminal

North: 4,50,000 tonnes; South: 6,00,000 tonnes; East: 3,50,000 tonnes; West: 5,00,000 tonnes.

The table header specifies cargo handled in 'thousand metric tonnes'.

2

Calculate the rail transshipment volume for each terminal

North: 4,50,000 × 40% = 1,80,000 tonnes
South: 6,00,000 × 65% = 3,90,000 tonnes
East: 3,50,000 × 50% = 1,75,000 tonnes
West: 5,00,000 × 30% = 1,50,000 tonnes

Rail transshipment share percentage is applied to total cargo volume of each terminal.

3

Compute revenue from rail transshipment for each terminal

North: 1,80,000 × ₹800 = ₹14,40,00,000 (₹14.40 crore)
South: 3,90,000 × ₹750 = ₹29,25,00,000 (₹29.25 crore)
East: 1,75,000 × ₹900 = ₹15,75,00,000 (₹15.75 crore)
West: 1,50,000 × ₹850 = ₹12,75,00,000 (₹12.75 crore)

Multiply rail transshipment tonnes by revenue per tonne.

4

Sum the rail transshipment revenues across all terminals

₹14.40 crore + ₹29.25 crore + ₹15.75 crore + ₹12.75 crore = ₹72.15 crore (₹72,15,00,000).

Total combined rail revenue is the sum of terminal-level rail revenues.

In a state handloom and textile development initiative, data was collected from three handicraft clusters: Cluster A, Cluster B, and Cluster C. A total of $1,200$ weavers are registered across these three clusters. The number of weavers in Cluster C is $300$ , of which $40\%$ are female. The number of weavers in Cluster A is $25\%$ more than the number of weavers in Cluster B. In Cluster B, the ratio of male to female weavers is $3:2$ . If the total number of female weavers across all three clusters is $480$ , what is the total number of male weavers registered in Cluster A?

Cevabı ve açıklamayı göster

Cevap: 300

Cevap

The total number of male weavers registered in Cluster A is 300.

By determining the total weavers in Cluster A (500) and Cluster B (400), and finding the female counts in Cluster C (120) and Cluster B (160), we deduce that Cluster A has 200 female weavers. Subtracting 200 from the 500 total weavers in Cluster A leaves 300 male weavers.

Adım Adım Çözüm

1

Determine total weavers in Clusters A and B combined

900 weavers

Subtract Cluster C weavers (300) from the overall total of 1,200 weavers.

2

Calculate weavers in Cluster B and Cluster A

Cluster B = 400 weavers, Cluster A = 500 weavers

Set Cluster A = 1.25 × Cluster B. Then 2.25 × Cluster B = 900, yielding Cluster B = 400 and Cluster A = 500.

3

Determine female weavers in Cluster C and Cluster B

Cluster C females = 120, Cluster B females = 160

40% of 300 is 120 for Cluster C. Based on the 3:2 male to female ratio in Cluster B, females account for 2/5 of 400, which is 160.

4

Calculate female weavers in Cluster A

200 female weavers

Subtract known females in B (160) and C (120) from the total 480 female weavers: 480 - (120 + 160) = 200.

5

Calculate male weavers in Cluster A

300 male weavers

Subtract female weavers in Cluster A from total weavers in Cluster A: 500 - 200 = 300.

Cevap: $₹4,000\text{ Lakhs}$

Cevap

The total financial loss incurred due to grain spoilage across Hub Alpha and Hub Gamma combined is

₹4,000\text{ Lakhs}

.

To find the total financial loss due to spoilage across Hub Alpha and Hub Gamma, we calculate the spoiled quantity for each hub based on the actual grain stored (in MT):
- Hub Alpha:

200,000\text{ MT} \times 4\% = 8,000\text{ MT}

- Hub Gamma:

240,000\text{ MT} \times 5\% = 12,000\text{ MT}

Total spoiled quantity

= 8,000 + 12,000 = 20,000\text{ MT}

.
At

₹20,000

per MT, total loss

= 20,000 \times 20,000 = ₹400,000,000

. Expressed in Lakhs (

1\text{ Lakh} = 100,000

), this equals

₹4,000\text{ Lakhs}

Adım Adım Çözüm

1

Calculate the actual quantity of spoiled grain in Hub Alpha

Spoiled grain in Alpha =

4\% \times 200,000\text{ MT} = 8,000\text{ MT}

Actual grain stored in Alpha is

200 \times 1,000 = 200,000\text{ MT}

and spoilage rate is

4\%

.

2

Calculate the actual quantity of spoiled grain in Hub Gamma

Spoiled grain in Gamma =

5\% \times 240,000\text{ MT} = 12,000\text{ MT}

Actual grain stored in Gamma is

3

Find the combined total quantity of spoiled grain

Total spoiled grain =

8,000\text{ MT} + 12,000\text{ MT} = 20,000\text{ MT}

The statements asserting that exactly two subjects equal 100, at least two subjects equal 130, and none of the subjects equal 20 are all mathematically accurate based on set region decomposition: exactly two subjects count is

50 + 20 + 30 = 100

; at least two subjects is

100 + 30 = 130

; and outside all sets is

300 - 280 = 20

.

Adım Adım Çözüm

1

Identify the central region (all three subjects).

The number of candidates preparing for all three subjects

n(GS \cap C \cap O) = 30

.

This value serves as the base subtraction term for all pairwise intersections.

2

Calculate the counts for candidates preparing for exactly two subjects.

GS and C only =

80 - 30 = 50

; C and O only =

50 - 30 = 20

; GS and O only =

60 - 30 = 30

. Total exactly two subjects =

50 + 20 + 30 = 100

.

Subtracting the triple intersection from each dual intersection isolates regions with exactly two subjects.

3

Calculate candidates preparing for only one subject.

Only GS =

180 - (50 + 30 + 30) = 70

; Only C =

140 - (50 + 30 + 20) = 40

; Only O =

120 - (30 + 30 + 20) = 40

.

Subtracting all overlapping regions from total set cardinalities yields single-subject counts.

4

Calculate the total union and the remainder outside all sets.

Total in at least one subject =

70 + 40 + 40 + 50 + 20 + 30 + 30 = 280

. Neither subject =

300 - 280 = 20

.

Applying inclusion-exclusion principle determines the complete universe coverage.
