Mahfuz has a total of to 480 in the denominations of one Taka, five taka and Ten taka. The numbers of different notes are equal. What is the total number of notes?

A 45

B 75

C 90

D None of these

Solution

Correct Answer: Option C

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.
