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 ?
45
60
75
90
Answer: Option
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.

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.

@All.

How 16 came means;

=> x + 5x + 10x = 16x.

@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.

Its very simple,
Just we take some secs to think about the ques that's enough,

Exp:
After reading question just go for the given options and divide by 3 as the denominations are.
Then add all those to the sum of 480.
1. 45/3 15 so each it come 240.
2. 60.....320.
3. 75....400.
4. 90...480.
