A man has Rs.355 in the denominations of one-rupee notes, 20-rupee notes and 50-rupee notes. The number of notes of each denomination is equal. What is the total number of notes that he has ?
Choose one.
A) 20  B) 15  C) 71  D) 40  E) 60
Let number of notes of each denomination be x.   Then x + 20x + 50x = 355   71x = 355   x = 5   Hence, total number of notes = 3x = 15.   Answer is 15.
