Check the last two digits of the number, if they are divisible by 4 then the entire number is divisible by 4.

Solution:

To check if a number is divisible by 4, there are certain rules.

If a number has more than 2 digits the way to check if it is divisible by 4 is;

Check the tens and ones place, if the last two digits are divisible by 4 then the entire number is divisible by 4.

Also if the tens digit is even then the ones place has to be 0, 4, 8. But if the tens digit is odd then the ones digit must either be 2 or 6.

$25

step-by-step explanation:
