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 |

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.

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

82500/5500 = 825/55 = 15,
15:1/10 = 15 * 10/1 = 150,
150* 25/100 = 150 * 1/4
= 150/4 = 37.5
150 + 37.5 = 187.5.
15:1/10 = 15 * 10/1 = 150,
150* 25/100 = 150 * 1/4
= 150/4 = 37.5
150 + 37.5 = 187.5.

I think the right answer is 36.
As market price is 180.
So after deducting 20% we will cost the cost price.
180*20/100 = 36.
180 - 36 = 144 that will CP.
Then, 144*25/100 = 36 and this will be the paper cost.
Hence, 36 should be the right answer.

180 is the selling price of the book. It includes the cost price of the book as well as the profit made on the book which is 20% of the cost price of the book. Together they make 180.

180*100/120 = 150.
150*25/100 = 37.5
150*25/100 = 37.5

Here 1st we need to find the cost price to find printing cost,
It is printing cost = (25*cp)/100.
We have formula for finding cp = (100*sp)/(100+gain%)
=(100*180)/(120)
=150
Therefore printing cost=(25*150)/100
=37.5
It is printing cost = (25*cp)/100.
We have formula for finding cp = (100*sp)/(100+gain%)
=(100*180)/(120)
=150
Therefore printing cost=(25*150)/100
=37.5

If the cost of paper is 20% of above it mean that = 100+20=120
So 120:25::180:x x=25*180/120=37.
So 120:25::180:x x=25*180/120=37.
