Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,

And the same either way.

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?

If 5 cats catch 5 mice in 5 minutes, how long will it take one cat to catch a mouse?

I don't get anymore wetter, no matter how much rain falls on me.

Before Mount Everest was discovered, what was the highest mountain in the world?

How many times can you subtract the number two from the number fifty?

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

What Am I?

They do not possess flesh or feathers or scales or bone
But still, they are blessed with fingers and thumbs of their own.

I have no life, but I can die. What am I?
