Answer» (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 |
