Question

if a number divisible by 2 then which of the following cannot be it's unit digit​

Answer 1

Answer: 1,3,5,7 and 9.

Step-by-step explanation:

• For a number to be divisible by 2 it must be having an even number or 0 at its unit place.
• The odd numbers such as 1,3,5,7 and 9 cannot be at its unit place as they are not divisible by 2.
• For example, 21÷2=10.5 which is not perfectly divisible.

         But 22÷2=11 is perfectly divisible by 2.

• Hence,1,3,5,7 and 9 must not be at the unit place.
