← Why smart people are stupid

Got the question right first time. I'm quite trained in maths, so I don't fall for that sort of thing easily:

x = bat y = ball

(all in cents for now, makes it easier)

x + y = 110 (total)

x - y = 100 (difference between them is 100 cents)

Second equation => x = y + 100, sub that into the first equation:

y + 100 + y = 110

2y = 10

y = 5

=> x = 105.

feels vilely smug

Okay. I'll get back to reading the rest of the article now...
