Question

A two digit number ‘2P’ is a number which is divisible by 2 and 3, what is the value of P?

Answer 1

The given number is 2P.
If 2P is divisible by 2, 3 then 2P should be a multiple of 6. $[\because \text{L.C.M}.of2,3\text{is}6]$
$\therefore 2P=24,30\dots \dots \dots \dots .$
$24\to 2+4\to \frac{6}{3}(R=0)$
$\therefore P=4$
