Answer 2

Solution : -

Check whether number is divisible by 3

a) 497

b) 5024

Now : -

a) 497

4 + 9 + 7 = 20

The sum of the digits is 20. As we know that , 20 is not a divisible of 3. So , 497 is not divisible by 3.

b)5024

5 + 0 + 2 + 4 = 11

The sum of the digits is 11. We know that , 11 is not a divisible of 3. So , 5024 is not divisible by 3.

Divisibility Rule of 3 : -

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

For Example : -

672 is divisible by 3 because the sum of digits is 15. (6 + 7 + 2 = 15) .
