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 |

100% + 20% = 180 rupees
Then 120x = 180
x = 180/120 = 1.5 * 25 paper cost = 37.5.
Then 120x = 180
x = 180/120 = 1.5 * 25 paper cost = 37.5.

Let CP = x.
x+20% of x = 180.
x = 150.
Cost of paper = 25% of 150 = 37.50.
x+20% of x = 180.
x = 150.
Cost of paper = 25% of 150 = 37.50.

If 120% cost is 180.
for 100%?
100/120 * 180 = 150.
25% of 150 IS 37.5.
for 100%?
100/120 * 180 = 150.
25% of 150 IS 37.5.
