Let CP of 20 mangoes be x
therefore,CP of 1 mango = x/20
let SP of 15 mangoes be x.
therefore, SP of 1 mango = x/15

Profit=SP-CP
=(x/15)- (x/20)
=(4x-3x)/60
=7x/60
Profit percent = [(7x/60)/(x/20)]*100
=700/3 %
=233 1/3 %

Let cp of 1 mangoe = 1Re
then cp of 20 mangoes = 20 Rs.
given sp of 15 mangoes = cp of 20 mangoes = 20 Rs
then sp of 1 mango = 20 /15
sp - cp = 20/15 - 1 = 5/15 = profit (sp>cp)
profit% = profit
               ____  x 100
                cost price
           = 5/15
              ____    x  100
                1
           = 100 / 3 = 33.33%
