First, if you enjoy the Friday Puzzle, I have just posted 101 of them here.
OK, to this week’s puzzle. On Friday I posted this puzzle…..
John is a gardener. The other day he bought a stack of posts and decided to put them around his garden. He planted the posts 2 feet apart and found that he needed 200 extra posts. Annoyed, he pulled up his posts and replaced them, but this time placing them 3 feet apart. Now he had 25 posts over. How many posts did he buy?
If you have not tried to solve it, have a go now. For everyone else, the answer is after the break.
The equation is..
2(x+200) = 3(x-25), which resolves to x=275.
UPDATE: Sorry, that was a typo, answer should be 475!
Did you solve it? Any other ways of getting to the answer?
