If the product 4864 x 9 P 2 is divisible by 12, then the value of P is:
2
5
6
8
None of these
Answer: Option
Explanation:

Clearly, 4864 is divisible by 4.

So, 9P2 must be divisible by 3. So, (9 + P + 2) must be divisible by 3.

P = 1.

Someone, please explain it clearly to understand the answer.

9 + p + 2 =11p.

If we add any number it must be divisible by 12.
So, if we add 1 then we get 11 + 1 = 12 is divisible by 12.

Why don't we take p=4 if we take p=4 it is also satisfying the condition right?

What if in the option both p=1 and p=4 is given?

Anyone, please explain.

Suppose we can ignore the 4864x because we need only p-value so I write;
9+p+2=11p (what we add in this to get divided from 12).
9+1+2=12 .........

So the p of value is 1.

I think you all understand now.

@Mayuri.

P can take 3 possible values 1, 4, 7; none of which are in the options.

Mayuri said:   5 years ago
Why only you are saying that : 9+p+2=12, where p=1.
Why can't we put p =4 instead of p=1?

If in the case of 48 if it has to be divisible by 12 then 4, 3 both should divide it if in que it is in form of 24*2 then how we will approach.
