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

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?

How will you decide which one of those is magnet?
