Answer 1

Hi friend, Harish here.

Here is your answer:

The number given is 7X3.

If this number as to be divisible by 3, Then 7 + x + 3 must be divisible by 3.

7 + X + 3 = 10 + X.

We know x can only be a single digit number.

And multiples of 3 between 10 to 20 is 12 , 15, 18

We know that, 12 = 10 + 2.

                        15 = 10 + 5
 
                        18 = 10 + 8.

Therefore possible values of x are 2 , 5, 8.
