Step-by-step explanation:

A number is divisible by 9 only when sum of it's digit is divisible by 9.

1. let the no. required be x.

Then, 2+x+1+8+9 = 20+x

To make it divisible by 9, we must add 7.

So, the required no = 7

2. let the no. required be x.

Then, 9+x+9+1+8 = 27+x

Since, 27 is already divisible by 9.

So, The required no. = 0

3. let the required no. be x.

Then, 5+4+x+5+1+8 = 23+x

To make it divisible by 9, we must add 4.

So, the required no. = 4

4. let the required no. be x.

Then, 9+0+8+x+1+8 = 26+x

To make it divisible by 9, we must add 1.

So, the required no. = 1
