I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

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

What can run but never walk, have a mouth that never speaks, have a head that never weeps, and have a bed but never sleeps?

If a wheel has 54 spokes, how many spaces are there between the spokes?

How can you write nineteen in a manner that if we take out one, it becomes twenty?

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.

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

How many letters are in the alphabet?

The more you take me, the more you leave me behind.
Who Am I?

If,

A = 1

B = 2

C = 3

...

...

Z = 26.

Based on above rule, you need to find an eleven letter word whose letter sum is equal to 52.
