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 |

20% above marked means c.p.=180-(180.20/100).
So the c.p. is = 144.
Now 25%(cost of paper in c.p.) of 144=144.25//100 = 36.
Then why answer is given as 37.5?
So the c.p. is = 144.
Now 25%(cost of paper in c.p.) of 144=144.25//100 = 36.
Then why answer is given as 37.5?

SP = 20% above the c.p.
Let x is original price of the goods.
Now,
x+20/100 * x = 180,
x+1/5 *x = 180,
6x = 900,
x =150,
Then,
150 * 25/100 = 36.50.
Let x is original price of the goods.
Now,
x+20/100 * x = 180,
x+1/5 *x = 180,
6x = 900,
x =150,
Then,
150 * 25/100 = 36.50.

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.
Now see the diagram for paper cost %, i.e. 25% of C.P, So 150*25/100 = 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.

Question says price is marked 20% above cost, Hence if cost was 100rs, the marked price will be Rs100 + 20% ie 120.

S.P. is 120% of C.P. wic is 180.
Thus c.p. is 100*180/120=150
nw Paper cost is 25%of 150 i.e. 25*150/100=37.50
Thus c.p. is 100*180/120=150
nw Paper cost is 25%of 150 i.e. 25*150/100=37.50

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.
