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.

Let no of 5 rupees note be x.
Then
The no of 10 rupees notes will be (70-x).
Therefore,
5x - 10(70-x) = 590,
x = 22.
Therefore, num of 10 rupees notes is 70 - 22 = 48.
