Question:
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?

A. 45
B. 60
C. 75
D. 90

Answer: Option D

Explanation:

Let the number of notes of each denomination be x.

Then x + 5x + 10x = 480

 16x = 480

 x = 30.

Hence, total number of notes = 3x = 90.
