A man has Rs. 480 in the denominations of one-rupee notes, five-rupee ...
Given:
- Total amount = Rs. 480
- Denominations: one-rupee notes, five-rupee notes and ten-rupee notes
- Number of notes of each denomination is equal

To find: Total number of notes

Solution:

Let the number of notes of each denomination be x.

- Number of one-rupee notes = x
- Number of five-rupee notes = x
- Number of ten-rupee notes = x

Total value of one-rupee notes = 1*x = x
Total value of five-rupee notes = 5*x = 5x
Total value of ten-rupee notes = 10*x = 10x

Total amount = x + 5x + 10x = 16x

From the given information, we know that the total amount is Rs. 480. Therefore,

16x = 480
x = 30

Hence, the number of notes of each denomination is 30.

Total number of notes = Number of one-rupee notes + Number of five-rupee notes + Number of ten-rupee notes
= 30 + 30 + 30
= 90

Therefore, the total number of notes that he has is 90.

Answer: (d) 90
