# How to find cost price in a problem concerning discount? [closed]

A dealer is selling an article at a discount of 5% on the marked price. (1) What is the selling price, if the marked price is 140.

(2) What is the cost price, if the marked price is 12% above the cost price?

i've got the first answer using the formula: Net SP= (100-D%)/100 * MP

so, SP=95/100 * 140 = 133

But now how do i proceed with the second question?

Marked price = 140

(2) What is the cost price, if the marked price is 12% above the cost price?

x * 1.12 = 140

x = 140/1.12

x = 125

cost price = 125
