Question

By selling 8 dozen pencils, a shopkeeper gains the selling price of one dozen pencils. Find his gain per cent.
​

Answer 1

Step-by-step explanation:

Let SP of one dozen pencils  be Rs.x

SP of 8 dozen pencils : Rs.x *8 = Rs.8x

Profit = SP of 1 dozen pensicls = Rs.x

CP of 8 dozen pencils : (8-1)=7 dozen = Rs.x  * 7 = Rs.7x

Gain % = Profit/CP*100 = (x/7x) * 100 = 100/7 = 14^2/7  %
