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?

The answer I give is yes, but what I mean is no. What was the question?

Replace the question mark with the correct number in below Picture:

You have an empty wine bottle with a cork that has been secured at the top in a normal way. There is a metal ring inside the bottle that is suspended by a string.

How can you make the metal ring drop to the bottom if you are not allowed to touch anything - not the bottle, not the cork, not the thread and not the ring?

Find the next number in the series?
2, 12, 36, 80, 150, 252, 392, _ ?

I have nine bottles of wine and one of the nine bottles is poisoned.
I need to find the poisoned bottle with two facts
(1) Poison is deadly, only a sip will cost death
(2) I have two mice to do so.

How should I do it?

I have a head like a cat and feet like a cat, but I am not a cat. What am I?

What has to be broken before you can use it?
