Now who is smarter?

Four MBA students were boozing till late night and didn't study for
the test which was scheduled for the next day.

In the morning they thought of a plan. They made themselves look as
dirty and weird as they could with grease and dirt. Then they went
up to the dean and said that they had gone to 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.

The Dean was a just person so he said that you can have a retest
after three days.

After 3 days they said they were ready. On the third day they
appeared before the dean. The Dean said that as this was a special
condition all four were required to be in separate rooms for the
test.

They all agreed as they had prepared well in last three days. The
test consisted of two question with a total marks of 100.

Q1. Write down your Name.(2 marks)

Q2. Which tyre burst ? (98 marks)
