Question

$2P$ is a number which is divisible by $2$ and $3$, what is the value of $P$

Answer 1

A number is $divisible$ by $2$ if the last digit is $0,2,4,6$ or $8.$
So, Here numbers would be like $20,22,24,26,28$
and

A number is $divisible$ by $3$ when sum of digits of the number is divisible by 3.
So, Here numbers would be like $21,24,27$

Therefore the number satisfying both conditions$\Rightarrow 27$
That is, $P\to 7$
