In a class of 48 students Meena's rank is 18th from the bottom. What is her rank from the top?

31st

The correct answer is Option (1) → 31st

TOTAL NUMBER OF STUDENTS = POSITION FROM TOP  +  POSITION FROM BOTTOM - 1

48 = POSITION FROM TOP  +  18  - 1

48 - 18 + 1 = POSITION FROM TOP 

30 + 1 = POSITION FROM TOP 

31 = POSITION FROM TOP
