Title: 499995
Post by Kitty on May 22^nd, 2003, 12:38pm

53654 + ***** + 45353 + ***** + 98763 + ***** + 24356 + ***** + 75897 + ***** ------- 499995

Find some numbers to replace the ***** in each row to make the sum work. (sorry if it is to easy for medium but i was not sure where to put it.)

Is there some extra constraint I'm missing? Cause there are a lot of ways to distribute the remaining difference over 5 numbers with 5 digits..

There is way to do it very quickly.

because [hide]499995 = 5 * 99999[/hide] you mean..

So there's sort of a time constraint, the faster you solve it the better your solution. I sorta like it..

I wouldn't try that..

Each missing row, added to the row above, sums to 99999.
So the missing number is just the number above, written backwards.

Did you make that up yourself?

[Edited] You are so quick on the draw, towr! I didn't even have time to edit or remove my answer before you replied. (I meant just subtract the row above from 99999 to get the missing row below.)

No my maths teacher told me ::).

The number are random however (except the 499995)

There is a typo in the puzzle: there should be a different number instead of 98763, or 4 stars below it.

oh, well. I just put random numbers down so i did not pay attention to that. Once you know the answer it does not really matter.

Sorry :-/
