Question

A trader mixes two types of pulses, A costing Rs. 80/kg and B costing Rs. 120/kg, in the ratio 3:2. He marks up the mixture by 25% on the cost price and allows a 10% discount. Find his net profit per kg.

A. Rs. 12

B. Rs. 15

C. Rs. 10

D. Rs. 14

Answer: Option A

Solution (By JKSSB Mock Tests)

Cost Price per kg of mixture = [(3 * 80) + (2 * 120)] / 5 = (240 + 240) / 5 = 96. Marked Price = 96 * 1.25 = 120. Selling Price = 120 * 0.90 = 108. Net profit = 108 - 96 = Rs. 12.

Correct Answer: Option D

Explanation:
Let original CP = 100x. SP = 90x. New CP = 80x. New SP = 90x + 55. Profit is 40% of 80x = 32x. New SP = 80x + 32x = 112x. 112x - 90x = 55. 22x = 55. x = 2.5. CP = 100 * 2.5 = Rs. 250.
