 Q. Common Information Question: 2/9 The price of the book is marked 20% above the C.P. If the marked price of the book is Rs. 180, then what is the cost of the paper used in a single copy of the book?
 ✖ A. Rs. 36.75 ✔ B. Rs. 37.50 ✖ C. Rs. 42.33 ✖ D. Rs. 44.25

Solution:
Option(B) is correct

Clearly, marked price of the book = 120% of C.P.

Also, cost of paper = 25% of C.P

Let the cost of paper for a single book be Rs. $n.$

Then,

$120 : 25 = 180 : n$

$⇒ n = \text{Rs. }\dfrac{25 × 180}{120}$

$= \textbf{Rs. 37.50}$
