Various Expenditures (in percentage) Incurred in Publishing a Book
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 |

As mention 20% above means 20% extra therefore total % is counted as 100 and 20% extra means 100+20 =120%.
Let the cost price be x.
And as mentioned in the question 20% above CP therefore.
x + 20% x = 180.
As 150 is the marked price and we are finding cost price therefore we are writing equal to 180.
Hence we get x = 150.
Now this is the CP = 150.
Paper cost 25% of CP as given in the question itself.
Total cost was 150.
Paper cost = 25/100 = 0.25*150 = 37.5.
Let the cost price be x.
And as mentioned in the question 20% above CP therefore.
x + 20% x = 180.
As 150 is the marked price and we are finding cost price therefore we are writing equal to 180.
Hence we get x = 150.
Now this is the CP = 150.
Paper cost 25% of CP as given in the question itself.
Total cost was 150.
Paper cost = 25/100 = 0.25*150 = 37.5.

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.

CP = 180.
SP = MARKET PRICE+20%.
180*20% = 36.
NEW SP = 180+36= 216.
PAPER COST 25% OF 216 = 54RS.
WHY WE ARE TAKING 120% AND HOW CAN ANY ONE HELP.
THANKS IN ADVANCE.

CP = 100%.
MP = 120%.
So,
120%------180.
25%--------?
Straight cancellation and cross multiplication simple,
Answer 37.50.

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.

Selling price is 180.00 ie 20% above the C.P, So C.P is 180/120*100 = 150,
Now see the diagram for paper cost %, i.e. 25% of C.P, So 150*25/100 = 37.5.

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