A man has Rs. 312, the denominations of one rupee notes, five rupee notes and twenty rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has? Correct Answer 36

Given:

Total amount = Rs. 312

The number of one rupee notes = number of five rupee notes = number of twenty rupee notes

Calculations:

Let the number of one rupee notes, five rupee notes and twenty rupee notes be x, each.

Now, on calculating the sum of the value of these notes, we get:

(1 × x) + (5 × x) + (20 × x) = 312

⇒ x = 12

So, the total number of notes = 12 + 12 + 12 = 36

∴ The total number of notes that he has is 36.
