Answer 2

Answer:

The Rule for 3:-

A number is divisible by 3 if the sum of the digits is divisible by 3...

This means that we need to add up the digits in the number and see of the answer is can be divided by 3 without a remainder...

5+2+a+3=10

adding 2 to 10

it becomes 12 ,which is divisible by 3..

so a=2

Now u can see 5223÷3=1741

Thus,it is divisible by 3..
