Question

A shopkeeper gives a discount of 30 percent on the marked price.the resulting selling price is equal to the cost price.what is his percent mark up?

Answer 1

Answer:

Let his CP = 100.

SP = 100 + 20% of 100 = 120.

As he gets this 120 after allowing a 10% discount. So,

SP = MP - 10% of MP

120 = 0.9MP

MP = 120/0.9 = 133.33.

Now, Increased price = 133.33 - 100 = 33.33.

% Increased = (33.33 * 100)/100 = 33.33%.
