Aaron is giving his exam and after spending a lot of time answering the questions, he asks the examiner about the time that is left for the exam.

The examiner is quite obtuse with her answer and says that the amount of time left is 1/5th of the time that has already passed.

Can you find out the amount of time left if the total time was 90 minutes?

Total time=90 min
Time passed=x min
Time left=y=x/5 min
x+y=90
x+(x/5)=90
x=75 min
y=75/5=15 min
Ans : Time left is 15 min
