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.

When No.of rupees are different denomination so how we can take 3x for total No.of rupees.

I think it's may be wrong @Jayakrishna. How can you get x=90?

Can you please explain it?

Denomination same and it is 3.

So 1+5+10 = 16.

So [480/16]x3 = 90. Its simple.

Please tell me is this solution is correct?

((1*x+2*x+3*x)/3) = 480.

So x = 90.
