Everly and I were playing on the merry-go-round at the local park. It was very large and we stood on opposite sides. As we spun the merry-go-round counter-clockwise, I threw a ball to Everly. Did the ball go to Everly, to the right or left of them?

Since the merry-go-round had moved while the ball was traveling to Everly the ball went to the right of them.

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

Favorite Use Is Attached To A String

A three-letter word I’m sure you know,
I can be on a boat or a sleigh in the snow,
I’m pals with the rain and honor a king,
But my favorite use is attached to a string.

What am I?

Show the answer »

A bow. It has three letters, the bow of a boat is the front, bows are found on the presents on Santa’s sleigh, rainbows come with the rain, one bows before a king and a bow and arrow requires a string.

Blindly Picking Socks

You have 12 black socks and 12 white socks mixed up in a drawer. You’re up very early and it’s too dark to tell them apart. What’s the smallest number of socks you need to take out (blindly) to be sure of having a matching pair?

Show the answer »

Three socks. If the first sock is black, the second one could be black, in which case you have a matching pair. If the second sock is white, the third sock will be either black and match the first sock, or white and match the second sock.
