Answer 2

Answer:

According to the question, his total gain in percentage is 16.64.

Step-by-step explanation:

We know that formula of Gain % is :

[ { ( 100 + common gain %)² / 100 } − 100 ] %  

Shopkeeper cheats to the extent of 8% in time of buying and selling fruits. So, common gain % is 8 %.    

Now, we have to put the values of common gain % in above formula and we get :  [ { ( 100 + 8 %)²  / 100 } − 100 ] %

= { (108 * 108)²  / 100 } − 100 ] %

= 116.64 - 100 %

= 16.64 %

Total gain in percentage is 16.64.
