Question

A shopkeeper marks a mobile 20 % above the CP and then gives at discount of 20 % find the loss. ​

Answer 1

Step-by-step explanation:

Let CP be 100

Mp = 100 + 20/100 × 100

= 100 + 20 = 120

Discount = 20%

When Mp and Discount% are given,

Sp = (100-d%/100) × MP

(100-20/100) × 120

= (80/100) × 120

= 96

Therefore, Sp = 96

CP = 100

CP >SP

Loss = CP - SP

= 100-96

= 4

Loss % = (4/100) × 100

= 4%
