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:
Let’s assume the number of each type of note is ‘x’.
The total value of one-rupee notes = 1 * x = 1x
The total value of five-rupee notes = 5 * x = 5x
The total value of ten-rupee notes = 10 * x = 10x
According to the given information, the total value of all the notes is 480 rupees. Therefore,
1x + 5x + 10x = 480
16x = 480
x = 480 / 16
x = 30
So, the number of each type of note is 30.
The total number of notes he has is the sum of the number of notes of each denomination, which is:
130 + 530 + 10*30 = 30 + 150 + 300 = 480
Therefore, the man has a total of 480 notes.
