Question

how much percent above the cost price should a shopkeeper mark his goods so that after allowing a discount of 10% on the marked price,he gains 8%?​

Answer 1

Answer:

20% above cost price

Step-by-step explanation:

let x = selling price

After discount, selling price = 0.9x

                         where 0.9x is 8% above cost price

                         Cost price = 0.9x/1.08 = 0.83333x

         Markup    X/0.83333x = 1.2

                                               = 20% above cost price

Answer 2

Answer:

we have to find the mrp at which if we give 10% discount we should get 8% profit.

for easy calculation: let the cost price be 100.

so profit is to be calculated on cost price

so amount for profit will be

100+8%100=108

then,

we have to find mrp at which if we give 10% discount we can earn 108

so 90%MRP= 108

or, MRP=(108×100)/90=120

required percentage upgrade in price

120-100= 20%
