Correct Answer : Option (C) - 37

Explanation :

Let the number of students in the class be 'x'.

Given if 1 is absent rest of people can be divided into 6 equal parts i.e (x-1)/6.........(1)

And given if 2 are absent rest of people can be divided into 7 equal parts i.e (x-2)/7.....(2)

From (1)&(2), we get

x-1/6 = ((x-2)/7) + 1

=> x = 37.
