… to see if you are.

From the Daily Mail (no on-line source available):

A brief IQ test is said to distinguish the brightest candidates for a job within three minutes.

3,500 college students took the test as part of its development; only 17 per cent got them all right. A third got all three wrong. Men made up two-thirds of those who got all three correct while women made up two-thirds who got all three wrong.

Here are the three questions:

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

2. If it takes five machines five minutes to make five widgets, how many minutes 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 many days would it take for the patch to cover half the lake?
