Rohit is ranked 18" from the top in his class. When counted from the bottom, he is ranked 36, What is the total number of students in the class?

53

Given that Rohit is 18^th from the top, means 17 students are above Rohit,

Rohit is 36^th from the bottom, means 35 students are below Rohit.

So, total students in the class = 17 + Rohit + 35

= 17 + 1 + 35

= 18 + 35

= 53.
