C.P. means what can anybody explain it? |

Sundar said: (Sep 25, 2010) | |

C.P = Cost Price (Manufacturing Cost) S.P = Selling Price. |

Spv said: (Dec 20, 2010) | |

Can anyone explain briefly? |

Poo said: (Jan 17, 2011) | |

Cost price is what a item or object costs. Selling price is the price at which the particular item or object is sold. |

Chets said: (Feb 16, 2011) | |

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 |

Arjun said: (Mar 19, 2011) | |

From where did we get cost of paper = 25percent of C.P? Can any body expliain? PLEASE. |

Yesh said: (Mar 20, 2011) | |

Its given in the pie chart. |

Robin said: (May 21, 2011) | |

From where does 180 comes from ? |

Siddharth said: (May 22, 2011) | |

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. |

Shreya said: (Jun 27, 2011) | |

From were does 120 comes? plesse explain. |

Reuben said: (Jul 19, 2011) | |

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

Divya said: (Jul 26, 2011) | |

Can anyone still clearly explain me this? |

Sam said: (Aug 30, 2011) | |

Firstly, Read the question thoroughly. 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 |

Joy said: (Oct 23, 2011) | |

What if i try to solve the sum by taking c.p. as x? Will the process be lengthy? |

Shan296 said: (Jan 17, 2012) | |

Please anyone tell me that why the calculations are based on sp? Can I use cp for calculation? |

Prabhat Ojha said: (Apr 24, 2012) | |

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. |

Pooja said: (Jul 19, 2012) | |

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 |

Sudheer Nag said: (Jan 31, 2013) | |

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

Chandresh said: (Feb 3, 2013) | |

Let x is the C.P. x+.2x=180. x=150. .25*x = 37.5. |

Sekhar Muthu said: (May 20, 2014) | |

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. |

Rahul said: (Jul 23, 2014) | |

Let CP = x. x+20% of x = 180. x = 150. Cost of paper = 25% of 150 = 37.50. |

Crazysatish said: (Sep 4, 2014) | |

CP = 100%. MP = 120%. So, 120%------180. 25%--------? Straight cancellation and cross multiplication simple, Answer 37.50. |

Prashant said: (Sep 13, 2014) | |

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. |

Manu said: (Oct 10, 2014) | |

How paper cost is 25%? |

Vijaya Lakshmi said: (Oct 13, 2014) | |

From where did we get cost of paper = 25 percent of C.P? |

Shubham Verma said: (Oct 17, 2014) | |

How 120 come? please explain. |

Sudheer said: (Oct 21, 2014) | |

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. |

Shreya said: (Oct 27, 2014) | |

As mention 20% above means 20% extra therefore total % is counted as 100 and 20% extra means 100+20 =120%. Let the cost price be x. And as mentioned in the question 20% above CP therefore. x + 20% x = 180. As 150 is the marked price and we are finding cost price therefore we are writing equal to 180. Hence we get x = 150. Now this is the CP = 150. Paper cost 25% of CP as given in the question itself. Total cost was 150. Paper cost = 25/100 = 0.25*150 = 37.5. |

Kiran Kumar C V said: (Nov 3, 2014) | |

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

Lalit said: (Jun 15, 2015) | |

But how 25% received? |

Stephen Bisto said: (Jun 25, 2015) | |

Please answer me S.P is it principle or constant that is 120 and C.P is 180 please help me about this number. |

Aditya Ganjoo said: (Aug 9, 2015) | |

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? |

Keyur said: (Oct 8, 2015) | |

I also face the same problem but after reading carefully I understood that. 1) Marked 20% above the C.P. 2) Marked price (SP) of the book is Rs. 180. Now SP = 120% of C.P. That not 20% of 180 but 120% of C.P = 180. 25% of C.P = X. So by taking ratio 37.5. |

Shadab Akhtar said: (May 16, 2016) | |

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. |

Vinothraj said: (Jun 29, 2016) | |

Cost of paper = 25% of CP . How it will comes? Please explain it. |

Navi said: (Aug 9, 2016) | |

Is mp = sp? Explain. |

Ushodaya said: (Nov 3, 2016) | |

@Crazysatish. I agree with you. Your answer is easy to understand. |

Sam said: (Nov 14, 2016) | |

Isn't the marked price 20% and not 120%? |

Harishankar said: (Jan 5, 2017) | |

@Manu. 25% came from pie chart. Please look into the diagram and question. |

Catherine said: (Jan 25, 2017) | |

120= 180, 1 = 1.5, 25 = 25x1.5 = 37.5. (short answer) |

Manish Chauhan said: (Feb 24, 2017) | |

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. |

Rohit687 said: (Mar 15, 2017) | |

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? |

Himanshu said: (May 1, 2017) | |

25% of CP why it is written like this? |

Jack said: (Jul 29, 2017) | |

I am not clear about this solution, Can anyone help me? |

Trisha said: (Sep 16, 2017) | |

Shouldn't it have been (25/100)*36=9? Explain. |

Kumar said: (Oct 5, 2017) | |

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. |

Ami said: (Dec 25, 2017) | |

@Sam thanks. Your explanation helped me alot. |

Sushmitha said: (Apr 26, 2018) | |

Can anyone explain me this to me? |

Sai Krishna said: (Jul 12, 2018) | |

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. |

Aniket said: (Dec 13, 2018) | |

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. |

Kavin said: (Feb 9, 2019) | |

How 120 comes? Please explain it. |

Chiru Kagani said: (Feb 20, 2019) | |

If 120% cost is 180. for 100%? 100/120 * 180 = 150. 25% of 150 IS 37.5. |

Nachiket said: (Jul 9, 2019) | |

I am not understanding this, Can someone explain, please? |
