Question

If u know then only answer the question

Answer 1

Cost price is equal to 400 Rs.
Profit= 400* 80/100
        = 320 Rs.

So , Marked price = 400+320
                              = 720

Discount given is 15% so 15/100 *720 
Discount given of Rs.108
So Selling Price = 720 - 108
                          = 612 Rs.
Actual Profit% made by the shopkeeper:-
400 - 108
= 292 Rs.
Profit% = 292/400 *100
So, Profit % = 73%
