Pawan is applying for a job with a high paying electrician known to hire people who can think outside of the box.
He tells Pawan that if he can solve a particular problem, he will get the job.
The boss puts Pawan outside the door to a room from which light can not escape.
Inside the room is a lamp.
On the wall next to Pawan are four switches, one of which works the lamp, the other three do nothing.
Pawan needs to figure out which switch works the lamp, but the boss has taken away all of his tools.
He has told Pawan that he may flip the switches to his heart's content, but he can only open the door to examine the lamp once.
What should Pawan do with the switches to ensure he gets the job?
