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.
