Multiple of 4 that have a odd number in the tens place. What value do they have in the ones place

Let us write some multiples of 4.

4,8,12,16,20,24,28,32,36,40.

We can see that 12,16, 32,36 are the multiples of 4 those have odd numbers 1 and 3 at tens places.

Now, we need to check the numbers on ones places of those multiples we got.

Ae can see that at ones places we have 2 and 6 numbers.

If we find some more mutiples, we get same odd numbers at tens places and same even numbers 2 and 6 at ones places.
