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 |

I think the ans will be 36,
Since MP is 20% more than CP and MP is given 180.
So, Calculate CP first which will be 20% less than MP(180) which will be 144. Then calculate 25% of CP(144), which will be 144/4 = 36.

Formula,
S.P = {(100 + gain%)* CP}/100.
C.P = (100 * SP)/100 + gain%.
Given,
S.P = 180.
Gain% = 20.
Therefore C.P = (100 * 180)/100 + 20.
=> 18000/120.
=> 150.
25% of C.P = (25 * 150)/100.
=> 37.5.

25% of C.P = (25 * 150)/100.
=> 37.5.

See 100% mp + 20% cp = ₹180 total book value,
So 120% = ₹180.
Let's take × = 1%.
120x = 180.
X = 180/120 = 1.5.
Which means 1% = ₹1.5.
& Now paper cost is 25%.
So, 25 × 1.5 = 37.5.
So 120% = ₹180.
Let's take × = 1%.
120x = 180.
X = 180/120 = 1.5.
Which means 1% = ₹1.5.
& Now paper cost is 25%.
So, 25 × 1.5 = 37.5.

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.

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.

CP + 20% of CP = 180.
CP + 20/100 of CP = 180.
Taking CP common,
(1 + 0.2)CP = 180
1.2CP = 180
CP = 180/1.2
CP = 150
Now,
25% of CP = X (paper cost).
20/100 * 150 = X.
X = 37.5.
CP + 20/100 of CP = 180.
Taking CP common,
(1 + 0.2)CP = 180
1.2CP = 180
CP = 180/1.2
CP = 150
Now,
25% of CP = X (paper cost).
20/100 * 150 = X.
X = 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.

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.

If I deduct 20% from the marked price, I get the CP. That is 20% of 180 = 144.
Now, 25% of CP is the paper cost. That is 144/4 = 36. Tell me how is that wrong?
