Question

Find a number which when added to 9,50,683 will make it completely divisible by 564

Answer 1

Step-by-step explanation:

In this case, they add up to 16. Ok, now, what’s the smallest number we could add to 16 to make it divisible by 9. A simple observation should get you to 2. And that’s your answer. Adding 2 to 4057 will give you 4059 which is divisible by 9.

Now, you could get cute about it and add -7 to the number giving you 4050, which is also divisible by 9. Normally, though, questions like this are usually seeking the smallest positive number to be added to achieve the result. Otherwise you could just add a negative sign to the number you started with, add them up (4057 + -4057) to get 0, which, technically, is also divisible by 9.

But don’t do it if this is a homework problem. I’m pretty sure your teacher won’t have my sense of humor.
