Least Sleepy Month

In what month do people sleep the least?

February, because there are fewer days.

Two cowboys live next door to each other and both have a corral for their cows in the back. One day they meet at the back of their homes, standing next to a wall dividing their corrals. The first cowboy gets to thinking and asks his neighbor for a cow so he can double his herd. The other cowboys replies, “That’s fine by me partner, cuz then we’ll have the same number of cows?” How many cows does each cowboy own?

Show the answer »

We’ll use A to represent the first cowboy and B for the second cowboy.

A + 1 = 2A, so A = 1.
A + 1 = B – 1, so B = 3.

Which Coin is Counterfeit?

You are given eight coins and told that one of them is counterfeit. The counterfeit one is slightly heavier than the other seven. Otherwise, the coins look identical. Using a simple balance scale, how can you determine which coin is counterfeit using the scale only twice?

Show the answer »

First weigh three coins against three others. If the weights are equal, weigh the remaining two against each other. The heavier one is the counterfeit. If one of the groups of three is heavier, weigh two of those coins against each other. If one is heavier, it’s the counterfeit. If they’re equal weight, the third coin is the counterfeit.

A match. You tear a match out of a matchbook and scratch the head to light it, then the red tip turns black from the flame.This is an exact duplicate of Tear One Off and Scratch My Head but I’m leaving it to avoid broken links.

Roll #5: 0

2. The answer is always even

How is the score determined?

Show the answer »

The solution is to count the dots (petals) surrounding the center dot (the rose).Only odd numbers have a center dot, so even numbers (2, 4 and 6) are worth zero.1 doesn’t have any surrounding dots, so it too is worth zero.The three has two dots surrounding the center, so it’s worth two.A five has four petals around the rose making it worth four.
