Question

after allowing a discount of 10% A shopkeeper make a profit of 20% by what percent is the Marked price above the cost price ​

Answer 1

Solution:

Let the cost price be 100 Rupees.There is gain of 20% so, Selling price will be 120 Rupees.

Sp=120

Let marked price be x

Then 90%of X=120

(90/100)x=120

x=120 ×100/90

=133.33

Above cost price=133.33-  100=33.33

So, marked price is 33.33 rupees more than CP.

So, shopkeeper must mark his good's price 33.33% more than cost price.
