Question

Write the smallest digit and the greatest digit in the blank space of the following number so that the number formed is divisible by $3$
$4765$_$2$ ?

Answer 1

$4+7+6+5+2=24$

If we add 0 then the digit is divisible by 3 $(24+0=24)$

0 is the smallest digit

$47652=4+7+6+5+0+2=24$

If we add 9 then the digit is divisible by 3 $(24+9=33)$

9 is the largest digit

$476592=4+7+6+5+9+2=33$
