A shopkeeper mixes two kinds of sugar: one costing ₹30/kg and the other ₹50/kg. He mixes them in the ratio 3 : 2 by weight. At what price per kg should he sell the mixture so as to gain 25% profit?
Show answer & explanation
Correct answer: D
Explanation
Given:
₹30/kg and ₹50/kg; Ratio = 3 : 2
Total Cost = 30 × 3 + 50 × 2 = 90 + 100 = 190
Total Quantity = 3 + 2 = 5
CP per kg = 190/5 = 38
SP = 38 × (125/100) = ₹47.5 per kg
