I am the fastest animal but cannot climb the tree. What am I?

I am not alive, but I grow; I don't have lungs, but I need air; I don't have a mouth, but water kills me. What am I?

It's a protector.
It sits on a bridge.
One individual can see directly through it, while others wonder what it hides.

Why are the Totals not tallying?

A father's child, a mother's child, yet no one's son.

Who am I?

A Man gave one of his sons 10 cents and another son was given 15 cents. What time is it?
Hint: Figure out the relation between time and number, is not so easy..:)

Get total of 120 by using five zeros 0,0,0,0,0 and any one mathematical operator.
Do you ?

What has hands, but can’t clap?

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?

A bus driver was heading down a street in Mexico. He went right past a stop sign without stopping, he turned left where there was a "no left turn" sign, and he went the wrong way on a one-way street. Then he went on the left side of the road past a cop car. Still - he didn't break any traffic laws. Why not?
