Story of 4 IIT Students
One night 4 iit 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.
They then went up to the dean and said that they had gone out 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.
Then dean was a just person so he said that you can have the retest after 3 days.
They said they will be ready by that time.
On the third day they appeared before the dean.
The dean said that this was a special condition test.
All four were required to sit in separate classrooms for the test.
They all agreed as they had prepared well in the last three days.
The test consisted of 2 questions with total of 100 marks.
Q.1. Write down your name —–(2 marks)
Q.2. Which tyre burst ——-(98 marks)!!

Q.-complex no.
what is represented by |z|= k , where k is some constant ?
Sol.
|z|= sqroot {( x*x) + (y*y)}
if(k>0) then it will represent a circle of radius (r= root of k)
if(k=0) it will represent a point ( x=0 ,y=0 )
if(k<0) then expression is wrong. as square root of any +ve real no never be less than zero
