Question

Question:-
If the product 3252 * 9P2 is divisible by 12, the value of P is​

Answer 1

Clearly 4864 is divisible by 4

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

So P=1.

Answer 2

P = 1

Divisibility test:

The divisibility test for 12 is that if the number is divisible by both 3 and 4, then it will be divided by 12.

In this question, two numbers are given 3252 and 9P2. If their product is divisible by 12 then we have to find the value of P.

These two numbers must be divisible by 3 and 4, then only their product will be divisible by 12.

We know that 3252 is divisible by both 3 and 4.

For 9P2 to be divisible by 3 and 4, we have to put 1 in place of P. Hence the number will be 3252 * 912.
