-
- 45
- 60
- 75
- 90
Correct Option: D
Let number of notes of each denomination be N.
According to question,
A man has ?480 in the denominations of 1 rupee notes , 5 rupee notes and 10 rupee notes.
Total value of notes = 480
1 x N + 5 x N + 10 x N = 480
⇒ N + 5N + 10N = 480
⇒ 16N = 480
⇒ N= 30.
Hence, total number of notes = 3N = 3 x 30 = 90
