A fruit vendor sells 15 kg of apples for ₹750, thereby gaining the cost price of 5 kg of apples. What is his profit percentage?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 33.33%.
Let CP of 1 kg = x
CP of 15 kg = 15x
Profit = 750 – 15x
CP of 5 kg = 5x
750 – 15x = 5x
⇒ 750 = 20x
⇒ x = 750/20 = 37.5
CP of 15 kg = 15 × 37.5 = 562.5
Profit percentage = (187.5/562.5) × 100 = 33.33%
