You are trapped in a room with no windows and a door that's locked the only furniture is a piano, a calender and a spring mattress. How do you eat, drink and get out!!!??
There was a fish tank, there were 10 fish in the tank, two of them died when they were born, 5 of them drown and another one drown.
How Many fish were left in the tank?
There is a tunnel. Inside is only one train track. A train comes in from the left at 2:00 and another train comes in from the right on the same track at 2:00 also. Both come out safely.
How was this possible?
