Two sections of class IX having 27 students in each section appeared for Mathematics olympiad. The marks obtained by them are shown below. 46, 31, 74, 68, 42, 54, 14, 61, 48, 37, 26, 8, 64, 57, 93, 72, 53, 59, 38, 16, 88, 56, 46, 66, 45, 61, 54, 27, 27, 44, 63, 58, 43, 81, 64, 36, 49, 50, 76, 38, 47, 77, 62, 53, 40, 71, 60, 45, 42, 34, 46, 40, 59, 42 One student is selected at random. Find the probability that selected student is having marks more than 49.

If 48 +64 = 44,53 +96= 46, 29 + 36 = 40, then 98 +57 = ?
