(i) 76 M 91
The given number = 76 M 91
Sum of its given digits = 7 + 6 + 9 + 1
= 23
The number next to 23, which is divisible by 9 is 27
Required smallest number = 27 – 23
= 4
(ii) 77548 M
The given number = 77548 M
Sum of its given digits = 7 + 7 + 5 + 4 + 8
= 31
The number next to 31, which is divisible by 9 is 36.
Required smallest number = 36 – 31
= 5
(iii) 627 M 9
The given number = 627 M 9
Sum of its given digits = 6 + 2 + 7 + 9
= 24
The number next to 24, which is divisible by 9 is 27
Required smallest number = 27 – 24
= 3
