1.

A man has Rs.480 in the denominations of one-rupee notes, five-rupee notes and ten-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has ?

 [A]. 45 [B]. 60 [C]. 75 [D]. 90

Explanation:

Let number of notes of each denomination be x.

Then x + 5x + 10x = 480

16x = 480

x = 30.

Hence, total number of notes = 3x = 90.

 Pushpa said: (Dec 16, 2010) How come 3x?

 Aparna said: (Dec 26, 2010) As the number of notes of different dinominations is same. And their are 3 kinds of notes. Therefore, 3*30=90.

 Ritu said: (Apr 9, 2011) I want short term rule (formula).

 Ramesh said: (Jun 17, 2011) One (rupee)+ Five(rupee) + Ten(rupee) = 16 (rupee) Rupees 480 has to be distbted in these denomination i.e, 16 so 480/16 = 30 one rupee 30 notes five rupee 30 notes ten rupee 30 notes total 90 notes.

 Manojit said: (Feb 7, 2012) Thank you Ramesh..

 Sumit said: (May 2, 2012) Thanks ramesh very easy form of method.

 Deep Goel said: (Jan 20, 2013) x+5y+10z=480 -> 1. x=y=z -> 2. x+y+z=? -> 3. From 2 we can say that x+5x+10x=480. 16x=480 : x=30. From 2&3 we get answer as 30+30+30=90.

 Raghu said: (Mar 10, 2013) Thanks to @Ramesh your explanation is clear but all problems are same pattern this formula use it or not tell me.

 Amit Tomar said: (Sep 13, 2013) When No.of rupees are different denomination so how we can take 3x for total No.of rupees.

 JayaKrishna said: (Oct 27, 2013) Please tell me is this solution is correct? ((1*x+2*x+3*x)/3) = 480. So x = 90.

 Vinitha said: (Jan 20, 2014) I think it's may be wrong @Jayakrishna. How can you get x=90? Can you please explain it?

 Hari said: (Feb 18, 2014) Divide the notes 30*10 = 300. 30*5 = 150. 30*1 = 30. Add = 300+150+30 = 480. No of notes = 90.

 Sayalee said: (Oct 22, 2014) Can you tel me if denomination is not equal what will be method.

 Ankita said: (Jan 21, 2015) Denomination same and it is 3. So 1+5+10 = 16. So [480/16]x3 = 90. Its simple.

 Sumeet said: (Jun 24, 2015) A man 20 notes in denomination of Rs.5 Rs.10 Rs.20. The total amount with him is Rs. 195 which of the can be the number of Rs.5 notes with him.

 Jahirul said: (Jul 22, 2015) 30*10=300 definition?

 Faruque said: (Aug 10, 2015) Thanks to everyone.

 Sakesh said: (Aug 24, 2015) 1 rupees notes 90 = 1*90 = 90. 5 rupees notes 90 = 5*90 = 450. 10 rupees notes 90 = 10*90 = 900. = 90+450+900/3. = 1440/3 = 480. No of notes 90.

 Naveenanu said: (Sep 19, 2015) How can come 16?

 Ammu said: (Oct 11, 2015) 3 1/2+5 1/5+?+2 1/4 = 11 1/3. Option = 1.11/60, 2.13/60, 3.23/60 4.29/60. [Any shortcut].

 Anurag said: (Dec 26, 2016) What if ratios are also given like 3:4:5 then how to solve it?

 Vibha said: (Dec 26, 2016) When ratio are different, then which formula I have to use?

 Ishika said: (Dec 26, 2016) Hi, Is this applicable even if it is mentioned that the denomination is in ratio and not equal?

 Ishika said: (Dec 26, 2016) @Amortya. Let no.of 5 rupee note be X. Then, No.of 10 rupee note will be (70-X). Therefore, 5X-10( 70- X) = 590, X = 22. Therefore num of 10 rupee note is 70-22 = 48. Correct me, if I am wrong.

 Kothimerla Ashok said: (Jan 28, 2017) Let no of 5 rupees note be x. Then The no of 10 rupees notes will be (70-x). Therefore, 5x - 10(70-x) = 590, x = 22. Therefore, num of 10 rupees notes is 70 - 22 = 48.
