If 347P is divisible by 9, then what is the value of P?1). 22). 33). 44). 7

Answer»

We KNOW that if the SUM of digits in a number is divisible by 9 then the number is divisible by 9.

Now 3 + 4 + 7 + P should be divisible by 9.

So, 14 + P should be divisible by 9.

Also P is a single DIGIT number.

The number after 14 which is divisible by 9 is 18.

So P is = 18 - 14 = 4.
