Answer 2

☆☆yor answer is here☆☆


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
Comparing both 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……%
