By selling 25 metres of cloth a trader gains the selling price of 5 metres of cloth. The gain percent of the trader in % is
-
- 25%
- 20%
- 28%
- 29%
Correct Option: A
Given in question , S.P. of 25m of cloth – C.P. of 25m of cloth = S.P. of 5m of cloth
∴ C.P. of 25m of cloth = S.P. of 20m of cloth
∴ C.P. of 20m of cloth = $ 20
and S.P. of 20m of cloth = $ 25
Gain = 25 - 20 = $ 5
| ∴ Gain percent = | × 100 = 25% | 20 |
Using the given formula :
Here, p = 25, q = 5
| Gain% = | % | p - q |
| Gain% = | % | 25 - 5 |
| Gain% = | % | 20 |
| Gain% = | × 100 = 25% | 20 |
