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 |

Cost price is what a item or object costs.
Selling price is the price at which the particular item or object is sold.

C.P = Cost Price (Manufacturing Cost)
S.P = Selling Price.
S.P = Selling Price.

Let the cost price of the book is 100, the given data clearly says that the selling/marked price is Rs.20 more than the Cost price, so the total cost of the book is 100+20 = 120.

Formula,
S.P = {(100 + gain%)* CP}/100.
C.P = (100 * SP)/100 + gain%.
Given,
S.P = 180.
Gain% = 20.
Therefore C.P = (100 * 180)/100 + 20.
=> 18000/120.
=> 150.
25% of C.P = (25 * 150)/100.
=> 37.5.
S.P = {(100 + gain%)* CP}/100.
C.P = (100 * SP)/100 + gain%.

S.P = 180.
Gain% = 20.

25% of C.P = (25 * 150)/100.
=> 37.5.

I also face the same problem but after reading carefully I understood that.
1) Marked 20% above the C.P.
2) Marked price (SP) of the book is Rs. 180.
Now SP = 120% of C.P. That not 20% of 180 but 120% of C.P = 180.
25% of C.P = X.
So by taking ratio 37.5.

If I deduct 20% from the marked price, I get the CP. That is 20% of 180 = 144.
Now, 25% of CP is the paper cost. That is 144/4 = 36. Tell me how is that wrong?
