Question

Consider the following statements : The numbers $24984,26784$ and $28584$ are

$I$ divisible by $3$.

.$II$divisible by $4$.

$III$ divisible by $9$ .

Which of these are correct?

• A. $I,II$ and $III$
• B. $I$ and $II$
• C. $II$ and $III$
• D. $I$ and $III$

Answer 1

The correct option is A $I,II$ and $III$

$2+4+9+8+4=27$ divisible by $3$ and $9$
$2+6+7+8+4=27$ divisible by $3$ and $9$
$2+8+5+8+4=27$ divisible by$3$ and $9$
Since all the three numbers have the last
two digits as $84$; a number divisible by $4$
all three are divisible by $4$
