I have a clock(12-hour format) and both the needles of the clock overlap at 12:00.
After how much time, they will overlap again?

I look at you, you look at me I raise my right, you raise your left. What am I?

There are three light switches outside a room. One of the switches is connected to a light bulb inside the room.
Each of the three switches can be either 'ON' or 'OFF'.

You are allowed to set each switch the way you want it and then enter the room(note: you can enter the room only once)

Your task is to then determine which switch controls the bulb?

You need to move three matchsticks to form three squares. Can you do it?

The more of this there is, the less you see. What is it?

Can you think of a smallest +ve number such that if we shuffle the digits of the number, the new number becomes double the original number?
