Final answer:
To find the total number of notes the man has, divide the total amount (480 rupees) by the value of each note (1 rupee, 5 rupees, and 10 rupees), and then find the common number of notes for each denomination.
The man has a total of 480 notes.
Step-by-step explanation:
To find the total number of notes the man has, we need to divide the total amount (480 rupees) by the value of each note (1 rupee, 5 rupees, and 10 rupees), and then find the common number of notes for each denomination. Let's call this common number x.
So, we have the equation: x + 5x + 10x = 480. Simplifying this equation gives us 16x = 480.
Dividing both sides of the equation by 16, we find that x = 30. This means that the man has 30 notes of each denomination. So, the total number of notes that he has is 1 x 30 + 5 x 30 + 10 x 30 = 30 + 150 + 300 = 480 notes.
