Question

If a person is selling a computer at discount of 5%,he still making a profit of 23.5%

Answer 1

Let CP = 100

MP = 100x

Discount = 5% of MP = 5x

SP = MP - Disc = 95x

Profit = SP - CP = 33% of CP

=> 95x - 100 = 33

=> x = 133/95

=> MP = 13300/95 = 140

=> CP must be marked up by 40%

Note :

Mark Price is always expressed as percent of cost price.

Discount always applied on MP.

MP - Discount = SP
