3.
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?
Rs. 36
Rs. 37.50
Rs. 42
Rs. 44.25
Answer: Option
Explanation:

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 = Rs. ( 25 x 180 ) = Rs. 37.50 .

C.P = Cost Price (Manufacturing Cost)

Cost price is what a item or object costs.

Selling price is the price at which the particular item or object is sold.

S.P. is 120% of C.P. wic is 180.
Thus c.p. is 100*180/120=150
nw Paper cost is 25%of 150 i.e. 25*150/100=37.50

From where does 180 comes from ?
Siddharth said:   1 decade ago
180 is the selling price of the book. It includes the cost price of the book as well as the profit made on the book which is 20% of the cost price of the book. Together they make 180.
