Question

If X123Y is divisible by 4 then find
the possible values of X and Y​. I need step by step explanation . pls appeal me

Answer 1

Answer:

Y = {2,6}

X = [0,9]

Step-by-step explanation:

A number that is divisible by 4 should always have 0, 2, 4, 6 or 8 in its units place.

If Y is 0, then X cannot take any value that will make the whole digit divisible by 4. Thus, Y cannot be 0.

If Y is 2, then X can take the any value between [0,9].

If Y is 4, then X cannot take any value that will make the whole digit divisible by 4. Thus, Y cannot be 4.

If Y is 6, then X can take the any value between [0,9].

If Y is 8, then X cannot take any value that will make the whole digit divisible by 4. Thus, Y cannot be 8.

Thus, Y can take the values 2 and 6 and X can take any value between [0,9].
