Answer [Detailed Solution Below]
Option 4 : 33.3%
Given:
The cost price of 20 pens is equal to the selling price of 15 pens
Formula used:
Gain = selling price – cost price
Gain % = [Gain × 100]/C.P
Calculation:
Let cost price be 1 pen is Rs. x
Then, the cost price of 15 pens = Rs. 15x
The selling price of 15 pens = Rs. 20x
According to the question:
Gain = 20x – 15x = 5x
Gain % = [5x × 100]/15x
⇒ 100/3 = 33.3%
∴ The gain percent is 33.3%.

If the cost price of 25 pens is equal to the selling price of 20 pens, then the profit per cent is
- 20%
- 25%
- 15%
- 5%
Correct Option: B
Let the C.P. of
each pen be Re. 1.
∴ C.P. of 20 pens = Rs. 20
∴ S.P. of 20 pens = Rs. 25
Profit = S.P. of 20 pens - C.P. of 20 pens = 25 - 20 = Rs. 5
∴ Profit percent = | Profit | × 100 |
C.P. of 20 pens |
Profit percent = | 500 | = 25% |
