Question

A shopkeeper marks his goods at 30 percent above the cost price and then gives a discount of 10 percent. Find his gain percent.

Sum

Solution

Let C.P. of the goods = Rs.100

M.P. of the goods = Rs.100 + Rs.30

= Rs.130

Discount =`10/100xx"Rs."130`

= Rs.`1300/100`

= Rs.13

S.P. of the goods = M.P. − Discount

= Rs.130 − Rs.13

= Rs.117

Gain = S.P. − C.P.

= Rs.117 − Rs.100

= Rs.17

Gain% `="Gain"/"C.P."xx100`

`=17/100xx100`

= 17%
