Question

A shopkeeper marked his good 20%above the C.P.he also allows a discount of 10%on the goods. Find his gain percent.

Answer 1

Method (1)

let CP = 100

MP = 120

SP = 120*90/100 = 108

gain = 108-100 = 8

gain% = 8*100/100 = 8% (ans.)

Method (2)

120 = 100(100+P)/90

12*9 = 100+P

P = 8% (ans.)
