Question

A shopkeeper buys a pencil at 10 for Rs 10 and sells them for 8 for Rs 10. find the profit percent.​

Answer 1

CP of 10 pencil = Rs 10

CP of 1 pencil = Rs10/10

CP of 8 pencil= 10/10*8

=8

SP of 8 Pencil= 10

Now,

Profit = SP- CP

= 10-8

= 2

Therefore,

Profit Percent= P/ CP*100%

= 2/ 10 *100%

20%
