price, a shopkeeper gains the price of
Om cloth. His gain percent is
None of these
33.33%
25%
20%​

Answer 1

Answer:

Point to be remembered is profit or loss is always calculated by taking the difference between Cost price and Selling Price on number of articles sold.

Since 30m of cloth is sold, it must be compared with cost price of 30m to determine profit or loss.

=> Profit = 30SP - 30CP

But profit is equivalent to SP of 6m of cloth.

=> 30SP - 30CP = 6SP

24SP = 30CP

SP/CP = 30/24

Profit = SP - CP = 30 - 24 = 6

Profit percentage = Profit/CP x 100

= 6/24 x 100 = 25%
