Who wins?

One night, four college students were playing till late night and didn't study for the test which was scheduled on the next day.

In the morning they thought of a plan. They made themselves look as filthy as possible with grease and dirt. Then, they went up to the Dean and said that they attended a wedding last night and on their return, the tyre of their car burst and they had to push the car all the way back and that they were in no condition to appear for the test.

So the Dean said they can redo the test after 3 days. They thanked him and said they will be ready by that time. On the third day, they appeared before the Dean. The Dean said that as that was a Special Condition Test, all four were required to sit in seperate classrooms for the test.

They all agreed confidently as they had prepared well for the last 3 days.

The test consisted of 2 questions with a total mark of 100.
