By selling 20 metres of cloth a man gains the selling price of 4 metres of cloth. The gain percent is
-
- 25
- 30
- 35
- 20
Correct Option: A
From question , S.P. of 20 metres of cloth = C.P of 20 metres of cloth + S.P of 4 metres of cloth
⇒ S.P of (20 – 4 = 16 ) metres of cloth = C.P of 20 metres of cloth
Let C.P of 1 metre of cloth = $ 1
∴ C.P of 16 metres of cloth = $ 16
S.P of 16 metres of cloth = $ 20
Gain = S.P of 16 metres of cloth - C.P of 16 metres of cloth = 20 - 16 = $ 4
| ∴ Gain % = | × 100 | C.P of 16 metres of cloth |
| Gain % = | = 25% | 4 |
We can find gain % with the help of given formula :
Here, p = 20, q = 4,
| Gain % = | p - q |
| Gain % = | 20 - 4 |
| Gain % = | × 100 = 25% | 16 |
