A fruit-seller buys lemons at 2 for a rupee and sells them at 5

A fruit-seller buys lemons at 2 for a rupee and sells them at 5 three rupees. What is his gain percent?

  1. 10%
  2. 15%
  3. 20%
  4. 25%

Answer

Cost price of 1 lemon = ₹ (1/2) = ₹ 0.5

Selling price of 1 lemon = ₹ (3/5) = ₹  0.6

So, profit = ₹  0.1

Profit % = 0.1/0.5 × 100 = 20%

The correct option is C.
