Question

Which of the following numbers can be the missing digit in the number 2344_6, if the number is divisible by 4?

• A. 4
• B. 2
• C. 6
• D. 5

Answer 1

The correct option is D

5

A number is divisible by 4 if the number formed by the last two digits of that number is divisible by 4.

If the missing digit is 4, that would make the last two digits 46, which is not divisible by 4.

If the missing digit is 2, that would make the last two digits 26, which is not divisible by 4.

If the missing digit is 6, that would make the last two digits 66, which is not divisible by 4.

If the missing digit is 5, that would make the last two digits 56, which is divisible by 4.
Hence, the missing digit is 5.
