# Thread: Lots of Confusion

1. ## Lots of Confusion

There was a real estate mogul who bought a piece of land for \$243, divided it into equal lots, and sold the entire package for \$18 per lot. (I know the price seems cheap but this was a long time ago!) The moguls profit on the entire deal was equal to what six of the lots had originally cost him. How many lots were in the piece of land?

<span style="background-color: #FFFF00; color: #000000; font-weight: bold"><font color=yellow>Say there were n lots. The mogul paid 243/n for each, so 6 of them cost 6 x 243/n. He receives 18 x n; this must be equal to 243 + 6 x 243/n. This is a quadratic equation with one positive solution: n = 18.</font color=yellow></span hi>

I think he means that one day he'll come up with a puzzle that takes you more than 30 seconds to solve! <img src=/S/grin.gif border=0 alt=grin width=15 height=15>
