A boy has Rs. 160 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 ?
Choose the correct choice from the following choices
A) 30  B) 110  C) 140  D) 130  E) 120
Let number of notes of each denomination be x.   Then x + 5x + 10x = 160   16x = 160   x = 10.   Hence, total number of notes = 3x = 30.   30
