Question

A dealer marks a damaged article at 10% above the cost price and then allows a discount of 10%. Find his gain or loss per cent

Answer 1

Let cost price=100₹

Marked price=110₹
(10% above cost price)

Discount(D)=10%
D=(10/100)×110
D=11₹

Selling price
​​​​=Marked price - Discount
=110-11
=99₹

As SP is less than CP, there is a loss.

%loss=(loss/CP)×100
=(1/100)×100
=1%
