8 boxes of a fruit were purchased for Rs. 9,600. 5 boxes were sold at a profit of 10% and 3 boxes were sold at a loss of 10%. What is the net gain in percentage?

  2. 2.5%

  3. 2%

  4. 2.25%

Show answer & explanation

Answer: (B) 2.5%

Explanation

Each box cost 9600/8 = Rs 1200. Profit on 5 boxes = 5 × 120 = 600; loss on 3 boxes = 3 × 120 = 360. Net gain = 240, and 240/9600 × 100 = 2.5%.
