Question

A shopkeeper sells a book at a discount of 10%. He earns a profit of 12%. Then the ratio of the C.P to the marked price of the book is ?

Answer 1

Ratio of CP : MRP = 45 : 56

Step-by-step explanation:

Let us assume the cost price is 100, and the 12% of profit on

a cost price ,

Then,

⇒ $100\times\frac{12}{100}$

12

Selling price (SP) is,

SP = 112

10% discount on MRP,

90% = 112

100% = $\frac{112}{90} \times{100}$

100%  = $\frac{1120}{9}$

Ratio of CP : MRP,

⇒ 100 : $\frac{1120}{90}$

⇒ 45 :  56
