We have shown you a regular water barrel as below. Without using any measuring device can you check if the barrel is more than half-filled or less than half-filled?

I have a hole in my back and legs I lack.
I live where I can’t breathe and I eat without teeth.
What am I?

How high do you have to count before you use the letter “a” in the English spelling of the whole number?

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?

I can sizzle like bacon,
I am made with an egg,
I have plenty of backbone, but lack a good leg,
I peel layers like onions, but still remain whole,
I can be long, like a flagpole, yet fit in a hole.

I am a mother. However, I never give birth.

I am a father. However, I never nurse my children.

Wandering is not possible for me, but standing still happens occurs rarely.

Who am I?

I have two coins.
* One of the coins is a faulty coin having a tail on both sides of it.
* The other coin is a perfect coin (heads on side and tail on other).

I blindfold myself and pick a coin and put the coin on the table. The face of the coin towards the sky is the tail.

What is the probability that another side is also tail?

The dirtier I get, the whiter I look. Who am I?

If a wheel has 54 spokes, how many spaces are there between the spokes?

A donkey is behind another donkey
I'm behind that second donkey
But there is a whole nation behind me

It is a murder you can describe in a word.
