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.

But 4864 is not divisible by 3 as per the condition of the number should be divisible by both 3 & 4.

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

@Mayuri.

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

Co prime numbers of 12 are 4 and 3. So we need to divide the numbers by 4 and 3.

Why we don't divide 4864 by 3 and 9p2 by 4?

Please let me know.

Khushi said:   1 decade ago
since 12=4*3
so the whole no must be divisible by both 4 and 3.

Why don't we consider 6, 2 as the factors for 12?
