The sum of three digit number is subtracted from the number.
The resulting number is always:
divisible by 6
not divisible by 6
divisible by 9
not divisible by 9
Solution:Option(C) is correct
Let the three digit number be $439$
Sum of digits $=16$
Difference $= 439-16 = 423$ which is divisible by 9.

This is the property which will be true for all. Doesn't matter how may digits you take it will be always divisible by 9.
ie.2,3,4,5,6...and so on

It holds for 153 too..
sum of digits $=9.$
subtracting 9 from 153 you get 144 which is divisible by 9
it holds for 6 also which is also given in the options

what if we take the example 153?

Let the $3$ digit number be: $XYZ$
As per the question we have to find the divisibility of number $P$ (let),
$\Rightarrow P=9 \times (11X+Y)$
which is divisible by 9.
So if the sum of three digit number is subtracted from the number. The resulting number is always divisible by 9.
ur answer also not divisible by 6 at all.
