Correct Answer - Option 2 : 36
th
Position of Pawan from left - 40th
Position of Ratan from left - 40 + 15 = 55th
Total number of persons is a queue = Position of Ratan from left + Position of Ratan from Right - 1
Position of Ratan from Right = Total number of persons in a queue - Position of Ratan from left + 1
Position of Ratan from Right = 90 - 55 + 1 = 36th
Hence, 36th is correct.
