1 . A man has Tk 480 in the denominations of one-taka notes, five-taka notes and ten-taka notes. The number of notes of each denomination is equal. What is the total number of notes that he has?

• A. 45
• B. 60
• C. 75
• D. 90
• D. None of these

Answer: Option D

Explanation:

Let, each denomination is x 
1x   +   5x   +   10 x  =  480
16x  =  480 
x =  30
So total no of notes  =  30   +   30   +   30  =  90
