### Mathy Birthday Problems

Last week, I turned 42. Here’s a math problem related to that number.

Take 27 cubes, numbered consecutively from 1 to 27. Arrange them into a magic cube so that every row, column, corridor, and space diagonal has a sum of 42.

If that’s too much for ya, try this problem instead. It’s a slight modification of a math problem that appeared on the birthday card given to me by colleagues.

Two men my age go out for drinks at 10 o’clock on a Saturday night. One of them drinks six 12-ounce beers, each of which is 8% ABV. The other drinks four Lynchburg lemonades, each of which contains one ounce of 80-proof Jack Daniels and one ounce of 60-proof triple sec. Assuming the men are the same size, which one gets more drunk?

The answer to the first question can be found at Math Palette.

The answer to the second one? Trick question. Men my age don’t go out after 10 o’clock.
