Grid
13 Answers
This would have been easy(ish) to me years ago, but now I'm stumped. My grandchildren have asked me to make a 3 x 3 grid with the columns labelled a, b, & c. The rows numbered 1, 2 & 3.
Now using the numbers 1 - 9 make row number 2 twice and row number 3 three times that of row number 1.
Now I don't know if I'm being tested (in which case I'm cheating) or if they don't know how to do it themselves!! They wont tell me.
Anyway it's driving me nuts.
What is the solution and is there an easy way (formula) for working this type of puzzle out?

Rather than starting with 123 for the top row I started with the maximum possible value which was 333 (as that would make the bottom row 999). of course 333 isn't permitted, nor is 332, 331 or 330. So the first possible number working backwards is 329. That didn't quite work, nor did 328- but 327 did
Thanks, Murphysrocks- I did wonder if there might be other solutions. I set up a spreadsheet this morning (dead easy- took about 30 seconds) and started to eliminate some columns (eg those ending in 5 on first row or any rows with repeated digits) but got bored after a minute and thought I'd try it later.
