Correct Answer - Option 5 : 50%
Given:
The sweet seller sells sweets at 20% profit
Formula used:
Profit or Gain % = {(Selling price – Cost price)/Cost price} × 100
Calculation:
Let Cost price of 1 kg = Rs. 1000
The selling price of 800 gm at 20% profit = {1000(100 + 20)}/100
The selling price of 800 gm = Rs. 1200
Cost price of 800 gm = Rs. 800
Profit or Gain % = {(1200 – 800)/800} × 100
⇒ (400/800) × 100
⇒ 50%
∴ The profit percentage of the sweet seller is 50%.
