For a smile in this hot weather.

 For a smile in this hot weather.

Two engineering students are waiting to give their oral viva test. The first student's turn comes, and he goes inside

External :-  Suppose you are travelling by a train, and suddenly it gets hot, what will you do?

Student:- I will open the window.

External :- Great, now suppose that the area of the window is1.5 sq.m and the volume of the compartment is 12 m3, the train is travelling at 80 km/hr in a Westerly direction and the speed of the wind is 5 m/s from the South, then how much time will  it take for the compartment to get cold?

The student can't answer, so he is marked as failed and he comes out. After coming out he tells that question to the second student.

The second student goes in and his viva starts.

External :- Suppose you are travelling by a train, and suddenly it gets hot, what will you do?

2nd Student :- I will remove my coat.

External :- It still is hot, then what?

Student:- I will remove my shoes.

External (angrily) :- If it still is hot, then what will you do?

Student:- I will spray water on my face.

External (Fuming) :- And what if you die due to the heat?

Student:- Mar jaaonga sir...but I will not open that window!
