Question

a boy bye 9 apples for rs 9.60 and sell them at 11 for rs12 find his gain or loss percent

Answer 1

Cp of 9 apples = 9.60
Cp of each apple = 9.60/9 = 16/15

Sp of 11 apples = 12
Sp of each apple = 12/11 and 16/15. 12/11 is bigger.
So , he got profit.
profit = 12/11 - 16/15
= 180 - 176/165
= 4/165
profit percentage= profit/Cp*100
=4/165÷16/15*100
=4/165*15/16*100
=25/11

=2.2727%
