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 ?
45
60
75
90
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.

Kindly providde us some simple tricks or easy. Which may help out eaisly.

How come 3x?

As the number of notes of different dinominations is same.

And their are 3 kinds of notes.

Therefore,

3*30=90.

I want short term rule (formula).

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.
