A Cognitive Reflection Test
« on: October 12, 2017, 07:35:19 AM »
Apparently this is a quick way to self-test your IQ. Do the test as quickly as possible. Your first answer to each question is the only one acceptable.

1. A bat and a ball cost £1.10 in total. The bat costs £1.00 more than the ball. How much does the ball cost?

2. If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?

3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

I got three correct answers in 40 seconds. So I now self-score myself at 80/- a pint. [Sorry - that should read "I award myself a pint of 80/-".]

You're way off the mark with the answer to number 3 H.  ;)

Thanks Mary. You have 2/3, but you've not made the same error as Highlander.  :)

Mine's an Estrella thanks.
