Question

A shopkeeper marks his goods $30$% above the cost price and gives on discount of $15$% on the marked price. What gain % does he make?

Answer 1

Let the cost of the product be $100$ Rs.

$MP=30+100=130$

$Discount=15\%$

$Discount=\frac{15}{100}\times 130=19.5Rs$

Selling Price$=130-19.5=110.5Rs$

Profit$=SP-CP=110.5-100=10.5Rs$

$Gain\%=\frac{10.5}{100}\times 100=10.5\%$
