3 4 5 28 20
4 5 6 45 30

91. To get the number in the fourth column, you add the numbers in column 1 and 2, then multiply by the number in column 2. f(n,m) = (n + m) * m
For example, f(2,3) = (2 + 3) * 3 = 15. Thus f(6,7) = (6 + 7) * 7 = 91

Four Cards

Four cards are placed in front of you on the table, each with a number on one side and a color on the other. The visible cards show 3, 8, red and brown. Which cards should you turn over in order to test the truth of the statement that if a card shows an even number on one face, then its opposite face is red?

four-cards

You’d need to turn over only the 8 and brown card. Only a card with an even number on one face and which is not red on the other face can invalidate the stated rule. If you turn over the 3 card and it’s not red, it doesn’t invalidate the rule, nor does turning over the red card and finding it has the label 3.

This test was devised by Peter Cathcart Wason and is known as the Wason selection task. Less than 10% of test subjects got it correct in two separate studies.

I’m Something You Might Eat But I Also Kill

I’m something you might eat, but I also kill.
I can cause blindness and burns.
Because of me, people lose limbs.
I’ve even been known to crash cars.

And yet I’m considered beautiful
Small children play with me and parents don’t mind.
Some people even live inside of me.

What am I?

Snow. Every kid has taken a bite of snow, but thousands of people die every year in snowstorms. Watch out for photokeratitis, otherwise known as snow blindness. And if you’re exposed to snow for too long, you can lose limbs to frostbite. Just an inch or two of snow makes them treacherous.

A recent snowfall makes the world white, and kids love to build snowmen, snow forts and have snowball fights. Some people live in igloos, built out of snow.
