Question

Which of the following numbers are divisible by 2 but not by 4?

• A. 28
• B. 324
• C. 2356
• D. 8026

Answer 1

The correct option is D 8026

$\Rightarrow$ Divisibility by 2: Any even number or number whose last digit is an even number i.e. 2,4,6,8 including 0 is always completely divisible by 2.

$\Rightarrow$ Divisibility by 4: If the last two digits of a number are divisible by 4, then that number is a multiple of 4 and is divisible by 4 completely.

$\Rightarrow$ $28,324$ and $2356$ are divisible by both 2 and 4.

$\Rightarrow$ $8026$ contains last digit 6, so it is divisible by 2.

$\Rightarrow$ $8026$ last two digit is not divisible by 4.

$\therefore$ $8026$ is the number which is divisible by 2 but not 4.
