Question

10. By selling 50 meters of cloth. I gain the selling price of 15 meters. Find the gain percent? A. 35% C. 40% D. 42 6/7% B. 30%.
​

Answer 1

Explanation:

Let the selling price of 1 meter of cloth be x

Then, S.P of 50 m of cloth = 50x

S.P of 15 m of cloth = 15x

Gain on 50 m of cloth = 15x

C.P of 50 m of cloth = 50x - 15x = 35x

Gain% = (Gain/C.P) × 100 = 15x × 100/35x = 300/7 = 42.86%
