Question

If the gain is one-fifth of the selling price, then the gain percentage is:
1. 80%
2. 20%
3. 16%
4. 25%

Answer 1

Correct Answer - Option 4 : 25%

Given :

The gain is one-fifth of the selling price

To find :

The gain percentage

Formula used :

Cost price = selling price - gain

gain% = (gain/cost price) × 100

Solution :

Let the selling price be x

So, the gain = x/5

⇒ The cost price = x - (x/5)

⇒ The cost price = 4x/5     ----(1)

⇒ Gain% = [(x/5)/(4x/5)] × 100

⇒ Gain% = 25%

∴ The gain percentage is 25%
