Consider the following statements: The numbers 24984, 26784 and 28584 are (1) divisible by 3 (2) divisible by 4 (3) divisible by 9 Which of these are correct?
(a)1 and 2
(b)2 and 3 )
(c)1 and 3
(d)1, 2 and 3
Answer
Answer (as printed): D
Explanation
(2 + 4 + 9 + 8 + 4) = 27, (2 + 6 + 7 + 8 + 4) = 27 and (2 + 8 + 5 + 8 + 4) = 27. So, each one is divisible by 3 and 9 both. Also, 84 is divisible by 4. So, each one is divisible by 4. Hence, each given number is divisible by 3, 9 and 4. So, the statements 1, 2 and 3 are all correct.
