A boy has Rs. 320 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 ? Options.
A) 60  B) 110  C) 140  D) 130  E) 120
Let number of notes of each denomination be x.   Then x + 5x + 10x = 320   16x = 320   x = 20.   Hence, total number of notes = 3x = 60.   60
