Why bother with a post grad course - waste of time? 17-10-2016

2. I'd be happy to help but I can't see the question - only a ___ ?
3. Hi Ed, thanks for offering to help.

Here is the question:

When he places a 1 at the end of this number it becomes three times larger than when he placed a 1 at the start.
Find the five-digit number. (I've solved this part using algebra and rules of multiples) (b) If you added a 1 in the same way to a 3-digit number how many times larger would it be?

It would be great if you could explain part b to me. Thanks

Does the multiple have to be an integer? In which case that can help us find values for the 3-digit number. Just from inspection I found that the multiple is 1 if the number is 111, but I suppose this would be considered a trivial solution.

Isn't this part of an ongoing mathematical contest/challenge? Are you sure you're allowed to be asking for help? At the very least, it seems rather dishonest that you haven't declared it to be one...
