Answer 2

Divisiblity of 3 says sum all the digit and check the no. in table of 3

Let's do it

$831 \\ \\ 8 + 3 + 1 = 12$

and yes 12 is in 3's table so 831 is divisible by 3 .

$524 \\ \\ 5 + 2 + 4 = 11$

11 is not in 3's table

$780 \\ \\ 7 + 8 + 0 = 15$

and yes 15 is in 3's table so

831 and 780 are the two numbers which are divisible by 3
