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.

Which point will the car reach to go out?

What you cannot hold but it is yours?

I came first on earth but second on the heaven.
I also came twice in a week but found just once in a year.
I stay away from months but you can find me in February.

What am I?

When my father was 31 I was 8. Now he is twice as old as me. How old am I?

What jumps when it walks and sits when it stands?

It comprises roots which nobody sees,
Much taller than those trees,
Up and up it goes,
Still it never grows?

In an interview, a boy was asked an unusual question 'How two persons sitting with a table in between them can't see each other?' He was unable to reply. Can you?

I make two people out of one. What am I?

What breaks yet never falls, and what falls yet never breaks?
