Answer 1

CP of 1 mango=1/18

SP of 1 mango=1/16

Profit=1/16-1/18

=18-16/288

=2/288

=1/144

Now profit %=1/144/1/18*100

=18/144*100

=100/8

=12.5%

Answer 2

let the cost price of the mango rs 1

then cp of 18 mango is 18rs

sp of 16 mango is rs 18

now the cp of 16 mango is rs 16

gain= sp-cp (16-12) =2

gain%=gain-cp÷100%

ANS=12.5%
