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?
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 . |
| 120 |

Question says price is marked 20% above cost, Hence if cost was 100rs, the marked price will be Rs100 + 20% ie 120.

Let x is the C.P.
x+.2x=180.
x=150.
.25*x = 37.5.
x+.2x=180.
x=150.
.25*x = 37.5.

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