Answer 1

$\huge\bold\purple{Answer}$

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

Now, let us check:

2020

2 + 0 + 2 + 0 = 4

As, 4 is not divisible by 3; 2020 is not divisible by 3.

2345

2 + 3 + 4 + 5 = 14

As, 14 is not divisible by 3; 2345 is not divisible by 3.

1350

1 + 3 + 5 + 0 = 9

As, 9 is divisible by 3; 1350 is also divisible by 3.

2206

2 + 2 + 0 + 6 = 10

As, 10 is not divisible by 3; 2206 is also not divisible by 3.

• Thus, 1350 is divisible by 3.
