Q1: 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 ?

A 45

B 60

C 75

D 90

ANS:D - 90

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.
