Question

State whether the following statement is True or False

A number is divisible by $18$, if it is divisible by both $3$ and $6$.

• A. True
• B. False

Answer 1

The correct option is B False

Checking a number is divisible by $18$ or not if it is divisible by both $3$ and $6$:

$6$ is the multiple of $3$, it means all the multiples of $6$ is divisible by $3$.

But, all the multiples of $6$ which are not the multiples of $18$ are not divisible by $18$.

For example: $6,12,24,30,42,48,60$ etc.

Hence, a number may or may not be divisible by $18$, if it is divisible by both $3$ and $6$.

Hence, the given statement is False.
