Answer 1

Answer:

If 1/4 of 1/3 = 5....so,

5*4=20

20*3

=60.

I think 60 students appeared for the exam.

Answer 2

Answer:

Suppose the total number of students appeared in the examination be 'x'

1/3 of x used unfair means.        = 1x/3

1/4 of 1x/3 were caught, this is equal to 5

1/4 * 1x/3=5

1x/12=5

x=12*5=60 students.
