Discussion
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: D
Let number of notes of each denomination be \(x\)
Then \(x + 5x + 10x = 480\)
\(\Rightarrow 16x = 480\)
\(\therefore x = 30\)
Hence, total number of notes \(= 3x = 90\)
