Answer 2

Step-by-step explanation:

Divisiblity rule of 3 says a no. is divisible by 3 if the sum of digits is 3, 6 or 9

Divisiblity rule of 9 says a no. is divisible by 3 if the sum of digits is 9

1) 7+2 = 9

It is divisible by both 3 and 9

2) 9+1+7 = 17 => 1+7 = 8

Neither divisible by 3 nor by 9

3) 4+6+8+9 = 27 => 2+7 = 9

It is divisible by both 3 and 9

4)7+9+8+7+5 = 36 => 3+6 = 9

It is divisible by both 3 and 9

5)9+8+8+9+7+4 = 45 => 4+5 = 9

It is divisible by both 3 and 9
