(it's a funny riddle)

Can you find the missing piece of the Porsche?

This is a most unusual paragraph. How quickly can you find out what is so unusual about it? It looks so ordinary, you'd think nothing was wrong with it. Actually, nothing IS wrong with it. But it is not as ordinary as you might think. If you think about it for a bit, you will find out why it is truly so unusual. So what is it? What is so unordinary about this paragraph?

There is a square of a particular number which when doubled, becomes 7 more than its quarter.

Can you find the number?

What do you see in the given picture?

Look at the picture and find out which square is not linked with any of the other squares.

I am thinking of a five-digit number such that:
The first and last digits are the same, their submission is an even number and multiplication is an odd number and is equal to the fourth number. Subtract five from it and we obtain the second number. Then divide into exact halves and we get the 3rd number.

What number I am thinking of?

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.

Make eight squares by moving only two matchsticks.
Note- Square can be of different sizes.

Take 9 from 6, 10 from 9, 50 from 40, and leave 6.

How Come ??
