Question

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

Answer 1

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.
