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.

One (rupee)+ Five(rupee) + Ten(rupee) = 16 (rupee)
Rupees 480 has to be distbted in these denomination i.e, 16
so 480/16 = 30
one rupee 30 notes
five rupee 30 notes
ten rupee 30 notes
total 90 notes.
