Rinki ranked 10th from the top and 28th from the bottom in a class. How many students are there in the class?

37

The correct answer is Option (2) → 37

THE LOGIC FOLLOWED HERE IS :

TOTAL NUMBER OF STUDENTS =  POSITION FROM LEFT + POSITION FROM RIGHT - 1

Rinki ranked 10th from the top

AND

28th from the bottom in a class

THEREFORE

TOTAL = 10 + 28 - 1

          = 38 - 1

          = 37
