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 |

120 : 25, why we need to divide CP1/CP2?

@All.
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.

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.

If profit is 1/5 of Cost price mean 1/6 of selling prince. i.e
profit on Selling price 180*(1/6)=30, then the cost price is 150*25% = 37.5.
profit on Selling price 180*(1/6)=30, then the cost price is 150*25% = 37.5.

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.

The marked price is 180..which is 20% above the C.P.
To find the C.P=180*20/100= 36.
C.P.= 180-36=144.
Why I am not getting the correct answer? Please tell me.

Given data,
Sp=180
Mp(or) sp = 120% of cp
Then;
180=(120/100)*cp.
Therefore, Cp = 150,
From pie chart paper cost = 25% of Cp.
= (25/100)*150.
= 37.5.
Sp=180
Mp(or) sp = 120% of cp
Then;
180=(120/100)*cp.
Therefore, Cp = 150,
From pie chart paper cost = 25% of Cp.
= (25/100)*150.
= 37.5.
