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 |

Cost price of whole book = 180*(5/6)=> Rs.150.
Cost of Book = Cost[Paper(25%)+ Printing(20%)+ Binding(20%)+ Royalty(15%)+ Promotion(10%)] = 100%=Rs.150.
Paper Cost=150X(25/100)= Rs.37.5.
Cost of Book = Cost[Paper(25%)+ Printing(20%)+ Binding(20%)+ Royalty(15%)+ Promotion(10%)] = 100%=Rs.150.
Paper Cost=150X(25/100)= Rs.37.5.

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.

1 = 1.5,
25 = 25x1.5 = 37.5.

25 = 25x1.5 = 37.5.
