Question

A shopkeeper marks the price of cold cream at ₹160. Find the cost price if after allowing a discount of 10% he still makes a profit of 20%.

Answer 1

Marked Price = ₹160

Discount % = 10 %

Hence Discount = 10 % of ₹160

= $\frac{10}{100}$ $\times$ 160

= ₹16

Hence Selling price = Marked price - Discount

= 160 - 16

= ₹144

Profit Percent earned = 20 %

If C. P S.P

100 120

? 144

C.P = $\frac{144\times 100}{120}$

= ₹120
