A bomb goes off.
Carnage.
One person, only a few feet away, survives! How can this be?

What goes up but never comes down?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

John is asked to stand behind Jacob and Jacob is asked to stand behind John. Both of them feel confused about it and don't know what to do?

But it is quite possible, do you know how?

They came out at night, without being called.
They lost at day, without being stolen.
Who are they?

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

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

I speak without a mouth, and hear without ears. I have no-body, but I come alive with the wind. What am I?

What question can you never answer yes to?

Before the start of the car race, John and Jacob have the same amount of fuel in their car. With this fuel, John can drive for 4 hours while Jacob can drive five hours.
After a time they realize that the amount of fuel left in John's car is 1/4th of the fuel in Jacob's.

For how long they are racing?
