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 |

CP + 20% of CP = 180.
CP + 20/100 of CP = 180.
Taking CP common,
(1 + 0.2)CP = 180
1.2CP = 180
CP = 180/1.2
CP = 150
Now,
25% of CP = X (paper cost).
20/100 * 150 = X.
X = 37.5.
CP + 20/100 of CP = 180.
Taking CP common,
(1 + 0.2)CP = 180
1.2CP = 180
CP = 180/1.2
CP = 150
Now,
25% of CP = X (paper cost).
20/100 * 150 = X.
X = 37.5.

If the selling price of the book is 120%.
Because cp=100% and profit = 20%.
Again, 120%= 180 rs. (Acc. To ques).
Then, 1%= 3/2.
Now, we know that the cost of printing is 25%,
So, the cost of printing in this case is,
25x3/2= 37.5.
Because cp=100% and profit = 20%.
Again, 120%= 180 rs. (Acc. To ques).
Then, 1%= 3/2.
Now, we know that the cost of printing is 25%,
So, the cost of printing in this case is,
25x3/2= 37.5.

Firstly, Read the question thoroughly. The question says that "The price of the book is marked 20% above CP(Cost Price) and the Marked price of the book is Rs 180. Marked Price is nothing but Sp(Selling price). These are the assumptions we can make from the question.
Soln: We need to find the CP now from the data given above.
Lets take the CP as 'x'. As the price of the book is marked(SP) 20% above the CP, the equation becomes:
x+20/100(x)=180
=> x=150
So, CP= Rs 150
Now, we need to find the cost of paper used in a single copy of the book.. i.e
25/100(150)=37.5

120= 180,
1 = 1.5,
25 = 25x1.5 = 37.5.
(short answer)
1 = 1.5,
25 = 25x1.5 = 37.5.
