A man has Rs. 720 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 answer.
A) 33  B) 38  C) 135  D) 90  E) 28
Let number of notes of each denomination be x.   Then x + 5x + 10x = 720   ⇒ 16x = 720   ∴ x = 45.   Hence, total number of notes = 3x = 135   Answer:135
