Well my english isn't good enough I meant the oldest meaning there was only ONE oldest so it's 2,2,9
Because it was too easy if there were 2 oldests.. only combinaison would be 1,6,6 Anyways, it was pure logic.. find all possibilities of 3 ages that gives 36. keep the two with the same total (13) since he said he knew the number of windows and then choose between 2-2-9 and 1-6-6 with the blue eye thing (only one with blue eyes) Because if i meant 2 oldest with blue eyes, you'd get down right there to 1-6-6 and therefore the window thing wasn't needed... It was a little trickier, but I "missed my shot" At least when you'll ask it to someone else, you'll know the correct way to ask it:) Etienne Jeff 'japhy' Pinyan wrote: > > On Nov 26, Jeff 'japhy' Pinyan said: > > >>Mr.Foo: What's the age of your children Mr. Bar? > >>Mr.Bar: I have 3 children, the multiplication of their ages is 36. > >>Mr.Foo: This doesn't help very much. > >>Mr.Bar: Well if you add their 3 ages, you get the number fo windows in > >>my house. > >>Mr.Foo: I know how many windows there are in your house, but that > >>doesn't tell me the age of your children. > >>Mr.Bar: The oldest have blue eyes. > >>Mr.Bar: Ahhhh, now I know > > > >Sets of three numbers that multiply to 36: > > 1 * 1 * 36 > > 1 * 2 * 18 > > 1 * 3 * 12 > > 1 * 4 * 9 > > 1 * 6 * 6 > > 2 * 2 * 9 > > 2 * 3 * 6 > > 3 * 3 * 4 > > I'm sorry, I left out the sums.
