The old twelve ball conundrum

I was just reminded of my ‘triumphant’ [ ;) ] solution to a mathematics puzzle while at the The Daily Telegraph!
It had evaded a young man (80+) ever since since uni days and he wrote to the paper asking to know the answer before he popped his clogs.
Normally solved algebraically (which I can’t stand), I solved it in my lunch break at the D.T. visually.
Checked by proper mathematicians and approved - this was published the next day (along with an algrebraic solution on another page)

FIRST - the LETTER TO THE EDITOR.

(Obviously, click on each to see whole image)


THEN, MY VISUAL SOLUTION:


This is for the delight of all those who don’t get on with algebra!
