Ques 29 GATE 2025 SET-2

""His life was divided between the books, his friends, and long walks. A solitary man, he worked at all hours without much method, and probably courted his fatal illness in this way. To his own name there is not much to show; but such was his liberality that he was continually helping others, and fruits of his erudition are widely scattered, and have gone to increase many a comparative stranger's reputation.""

Ques 32 GATE 2025 SET-2

A business person buys potatoes of two different varieties P and Q, mixes them in a certain ratio and sells them at 192 per kg.
The cost of the variety P is 800 for 5 kg.
The cost of the variety Q is 800 for 4 kg.
If the person gets 8% profit, what is the P:Q ratio (by weight)?

A

5:4

B

3:4

C

3:2

D

1:1


(a) is the correct answer.

The cost per kg of each variety
Variety P: 800 for 5 kg
Cost per kg of P = 800 ÷ 5 = 160/kg
Variety Q: 800 for 4 kg
Cost per kg of Q = 800 ÷ 4 = 200/kg

The cost price of the mixture
Given: Selling price = 192 per kg and Profit = 8%
Using the formula: SP = CP × (1 + profit%)
192 = CP × 1.08
CP = 192 ÷ 1.08 = 1600/9 per kg

Using the mixture rule
Let the ratio of P:Q be x:y (by weight)
Cost of mixture per kg = (x × 160 + y × 200) ÷ (x + y)
This should equal 1600/9:
(160x + 200y) ÷ (x + y) = 1600/9
9(160x + 200y) = 1600(x + y)
1440x + 1800y = 1600x + 1600y
1800y - 1600y = 1600x - 1440x
200y = 160x
y/x = 160/200 = 4/5
Therefore, x:y = 5:4

Answer: P:Q = 5:4

Ques 35 GATE 2025 SET-2

Which of the following statements is/are INCORRECT?

A

As the depth of the ground water table from the ground surface increases, the effective stress in the soil decreases.

B

Bulking of the moist sand is due to the capillary action in the sand.

Ques 36 GATE 2025 SET-2

From a flow-net diagram drawn under a concrete dam, following information are obtained: (i) The head difference between upstream and downstream side of the dam is 9 m. (ii) The total number of equipotential drops between upstream and downstream side of the dam is 10. (iii) The length of the field nearest to the toe of the dam in the downstream side is 1 m.
