Question

A dishonest shopkeeper does 2% dishonesty at the time of buying and 2% dishonesty at the time of selling.find his percentage gain.

Answer 1

Let cost price of 1 unit goods = Rs.1
Suppose he purchases 100 unit goods.
Then, total cost price = Rs.100

Due to cheating of 2% at the time of buying,he actually pays.
100- 2= Rs. 98. Suppose he sells this 100 units with cheating of 2% then the selling price = 100+2=Rs.102

Profit percentage =( (S.P. - C.P.)/C.P.)*100

=((102-98)/98)*100=(4/98)*100=4.08%

Ans= 4.08%
