We know that the given number \( \overline{98215x2}\) is divisible by 4.
A number is divisible by 4 only when the number formed by its digits in unit’s and ten’s place is divisible by 4.
i.e., x2 is divisible by 4
Expanding x2,
10x + 2 = multiple of 4
Here x2 can take values 2, 12, 22, 32, 42, 52, 62, 72, 82, 92
So values 12, 32, 52, 72 and 92 are divisible by 4.
x can take values 1,3,5,7 and 9
