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 ?
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.

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.
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.

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

Please tell me is this solution is correct?
((1*x+2*x+3*x)/3) = 480.
So x = 90.
((1*x+2*x+3*x)/3) = 480.
So x = 90.

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

Divide the notes 30*10 = 300.
30*5 = 150.
30*1 = 30.
Add = 300+150+30 = 480.
No of notes = 90.
30*5 = 150.
30*1 = 30.
Add = 300+150+30 = 480.
No of notes = 90.
