Show answer & explanation

Given that
By selling 24 items, a shopkeeper gains the selling price of 4 items.
According to the question
S.P. of 24 items - C.P. of 24 items = S.P. of 4 items
S.P. of 24 items - S.P. of 4 items = C.P. of 24 items
S.P. × 20 = C.P. × 24
S.P./C.P. = 24/20 = 6/5
Hence, gain % = [(S.P. - C.P.)/C.P.] × 100 = [(6 - 5)/5] × 100 = 20%
