A man has Rs. 480 in the denominations of one-rupee notes, five notes and ten-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has? Correct Answer 90

Given:

A man has total amount Rs. 480

Calculation:

Let the number of notes for each denomination be x

⇒ 1 × x + 5 × x + 10 × x = 480

⇒ 16x = 480

⇒ x = 30

Total number of notes he has

⇒ 30 × 3 = 90

∴ There are total 90 notes.
