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

Total rs = 480,
no of one rupees note = no of 5 rupees note = no of 10 rupees note = x.
So, x + 5x + 10x = 480,
16x = 480,
x = 30,
Then total no of notes = 3 * 30 = 90.
no of one rupees note = no of 5 rupees note = no of 10 rupees note = x.
So, x + 5x + 10x = 480,
16x = 480,
x = 30,
Then total no of notes = 3 * 30 = 90.

The number of notes of each denomination is equal means:
No of one rupee notes = no of five rupee notes = no of ten rupee notes.
x + x + x = 3x.
No of one rupee notes = no of five rupee notes = no of ten rupee notes.
x + x + x = 3x.
