Let CP of 1= Rs1
CP of 20= Rs20
SP of 15= Rs20 (as per condition is given)
CP of 15= Rs15
hence gain=(SP of 15)- (CP of 15) =Rs5
gain% =(5/15)*100= 33.33%

if the c.p of 'm' articles is equal to selling price of 'n' articles then %of gain or loss = (m-n/n)* 100

(20-15/15)*100 => (5/15)*100 => 33.33%
