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.

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.
