Question

A shokeeper marked his goods 20%above the
c.P and allows a discount of 15% what percentage does he gain or loss

Answer 1

Method (1)

let CP = 100

MP = 120

SP = 120*85/100 = 102

Gain = 102 - 100 = 2

Gain % = 2*100/100 = 2% (ans.)

Method (2)

120 = 100(100+P)/85

12*85 = 1000+10P

10P = 1020-1000

P = 20/10 = 2% (ans.)
