Question

By selling 33 m of cloth ramesh gained the cost price of 11 m the gain percent is

Answer 1

We have:
Gain on selling 33 m=(SP of 33m) - (CP of 33m)
SP of 11m=(SP of 33m) - (CP of 33m)
CP of 33m=(SP of 33m) - (SP of 11m)
CP of 33m=SP of 22m

Let the CP of each metre be Rs.x . Then,

CP of 22m=Rs.22x
SP of 22 m=CP of 33m=Rs 33x

Gain on 22m of cloth=Rs.11x

Gain%=(11x/22x×100)%
=50%
