Correct Answer - Option 3 : 28.57%
Given:
The fruit seller sells fruits at 10% loss.
Formula used:
Profit or Gain % = {(Selling price – Cost price)/Cost price} × 100
Calculation:
Let be 1 gram = 1 rupees
Let Cost price of 1 kg = Rs. 1000
The selling price of 700 gm at 10% loss = {1000(100 – 10)}/100
The selling price of 700 gm = Rs. 900
Cost price of 700 gm = Rs. 700
Profit or Gain % = {(900 – 700)/700} × 100
⇒ (200/700) × 100
⇒ 28.57%
∴ The profit percentage of fruit seller is 28.57%.
