One type of pulses is sold for ₹72 per kg at a 20% profit. Another type is sold for ₹60 per kg at a 25% profit. These two varieties are mixed in the ratio 3:1, and the mixture is sold at ₹68.4 per kg. What is the overall profit percentage?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Profit of 20%
CP of first type = 72/1.2 = ₹60 per kg
CP of second type = 60/1.25 = ₹48 per kg
Mixture cost price = (3 × 60 + 1 × 48)/4 = 228/4 = ₹57 per kg
Profit = 68.4 - 57 = 11.4
Profit percentage = (11.4/57) × 100 = 20%
