Gemini:

Your reasoning is wrong, .05 is the correct answer. If the ball costs $.06, then the ball will cost $.98 more, not $1

Hmm…. interesting point Chris. If collaboration is essential to the widget creation, the number would be much different.

anything over .05 cents would work in that calc

or even the opposite the ball cost .04 and the bat cost 1.06

for question #1 who says it has to be .05 why can’t the ball cost .06 than the bat would cost 1.04 which is still more than 1.00???

If it takes 5 machines 5 minutes to make 5 widgets, how long would it take
100 machines to make 100 widgets?

Answer Quote:
“For question #2, an intuitive response would be that ’5=5=5 so 100=100=100′. However, if it takes a single machine 5 minutes to make a single widget, even a million machines can make a million widgets in 5 minutes. The correct answer is therefore 5 minutes.”

I got hung up on this one because I didn’t think of the answer the same way.

If 5 machines working in tandem make a rate of 1 widget per minute. Then if you multiplied the number of lines of machines by 20 to accumulate 100 machines as a whole, it would still only take 5 minutes to make 100 widgets because each line would produce their 5 widgets in 5 minutes. I suppose that’s a collaboration between intuition and IQ?

The initial intuitive flaw is assuming the machines work in a forced order and by adding more machines you are adding more time.

I think the REAL question that these questions are asking is “John answered all three questions correctly in 5 minutes. If John were to ever mention this publicly, how long would it take for some idiot to punch him in the face?”

@ PINhead

The keyword is MORE. 1 dollar MORE than the ball. If the ball costs $.10 then the bat costs 1+.1 or 1.10. 1.10 (bat) plus .10 (ball) is 1.20.
