Question

A shopkeeper marks his goods 30% above the cost price and gives a discount of 15% on the marked price what gain % does he make

Answer 1

let CP be RS 100
MP is 30% more than CP

mp = 100+30% of 100
= 100+30/100*100
=RS 130
discount %= 15%
SP=130*(100-15)/100
=130*85/100=RS 110.50
gain = SP-CP
= 110.50-100
=RS 10.50
gain %=10.50*100/100
=10.50% ans

Answer 2

Answer:

Let the cost of the product be 100 Rs.

MP=30+100=130

Discount=15%

Discount=

100

15

×130=19.5Rs

Selling Price=130−19.5=110.5Rs

Profit=SP−CP=110.5−100=10.5Rs

Gain%=

100

10.5

×100=10.5%
