In a certain driver's class the 3/4 of the students took the
test on monday so say total no of students are 80.

3/4 of 80 = 60 took test on monday.

then the ques says that 4/5 of the remaining
took the test on tuesday that means

4/5 of 20 = 16.

so students took the test on tuesday in terms of x that is 60
is 16/60 = 4/15.

Hence B is the answer.
