Correct option is D
Given:
Suraj ranked 18th from the top and 67th from the bottom in his class.
Let's check:
The total number of students in the class.
Formula:
Total students = (Rank from top + Rank from bottom) −1
= (18 + 67) −1
= 85 −1
= 84
So, the total number of students in the class is: 84
Thus, the correct option is: (d)
