Vikram and Betal

Vikram and Betal were kind of enemies as well as friends. Betal was a ghost who had a different world of his own and if someone entered his world. He would ask him or her riddles and logical reasoning questions. 

One day, Vikram Sharma, the holder of one of the biggest companies in the world entered Betal place where he saw him eating Turkish delights. Vikram was about to go but then Betal saw him closed the door to the outside world. Then, Betal said that welcome, if you want to go out, you have to solve three questions.

But Vikram was one of the most intelligent people in his city. So, he tells the answer quickly and after that, the Betal said that you seemed intelligent. The Vikram said that what you do with the people who didn't answer your question. The Betal said, "They get trapped here for a month and then I let them go." Ok, thanks now I am going back.
