Remove two matchsticks to make the below equation correct.

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?

If we add four times the age of John four years from now to five times his age five years from now we get ten times his current age.

How old will John be two years from now?

How will you measure 15 minutes using two hourglasses of 7 minutes and 11 minutes respectively?

If we tell you that there is a relation between the numbers and letters in the given figure, can you analyze it and find the missing letter in the last box?

In a boat, the father of a sailor's son is sitting with the son of the sailor. However, the sailor is not present on the boat.

Can this even be possible?

I am quite hot but become too cold if you remove the first two letters. What am I?

What has six faces, but does not wear makeup, has twenty-one eyes, but cannot see?

John can place six large boxes or nine small boxes into a carton.
