Question

If the cost price of 15 pens is equal to the selling price of 20 pens, then the loss percent is

1. 25%
2. 20%
3. 15%
4. 18%

Answer 1

Correct Answer - Option 1 : 25%

Given:

15CP = 20SP

CP is cost price, SP is selling price

Formula Used:

Loss percent = (CP – SP)/CP × 100

Calculation:

15CP = 20SP

⇒ 3CP = 4SP

⇒ CP/SP = 4/3

⇒ Loss = 4 – 3 = 1

Loss percent = Loss/CP × 100

⇒ Loss percent = 1/4 × 100

⇒ Loss percent = 25%

∴ Total loss percent is 25%.
