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.

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.

@Amortya.
Let no.of 5 rupee note be X.
Then,
No.of 10 rupee note will be (70-X).
Therefore,
5X-10( 70- X) = 590,
X = 22.
Therefore num of 10 rupee note is 70-22 = 48.
Correct me, if I am wrong.
