• B. 56112
• C. 49653
• D. 89445

Answer 1

Answer:

C. 49653

Concept: Divisibility law of 9 ⇒ A number is divisible by 9 if the sum of its digit is divisible by 9. Calculation: Option 1: 58556 Sum of the digits = 5 + 8 + 5 + 5 + 6 = 29 (not divisible by 9) Option 2: 56112 Sum of the digits = 5 + 6 + 1 + 1 + 2 = 15 (not divisible by 9) Option 3: 49653 Sum of the digits = 4 + 9 + 6 + 5 + 3 = 27 (divisible by 9) Option 4: 89445 Sum of the digits = 8 + 9 + 4 + 4 + 5 = 30 (not divisible by 9) ∴ Option 3 is correct.
