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.

If I remove one from eleven it becomes Ten and if I remove one from nine also becomes Ten. How?

I am beautiful, up in the sky. I am magical, yet I cannot fly. To people I bring luck, and to some people, riches. The boy at my end does whatever he wishes. What am I?

How many letters are in the alphabet?

How many times can you subtract the number 5 from 25?

Give it food and it will live; give it water and it will die.

I’m tall when I’m young, and I’m short when I’m old. What am I?

I am a white box having no key or lid.
Yet there is a golden treasure inside it.

What Am I?

John enters a small room. The Door Closes.
When the door opens, John is in a larger room.

Explain?

Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I?
