Brain Stretchers
1) At the movie theater, there are six seats in a row.
Elmer and Derek have three people between them.
Casey sits next to Elmer, but not next to Benjamin.
Alex is on the end, but Elmer isn't.
Between which two people is Fred sitting?
Hint #1: Draw a picture.
Hint #2: Do you have to write out the people's full names?
What do you notice about the first letter of each name?
2) Meredith's mom has four children.
The first child is named April.
The second child, May.
The third child, June.
What is the name of the fourth child?
3) Three men in a restaurant order a $15 meal to share. Each man contributes $5. The waiter takes the money to the chef who recognizes the three men as friends and asks the waiter to return $5 to the men.
The waiter not only dislikes math (!) but he's also dishonest (!!). Instead of splitting the $5 among the three men, he simply gives them $1 each and pockets the remaining $2 for himself.
Now each of the men effectively paid $4, and the three of them paid $12 total. Add the $2 in the waiter's pocket and we have a total of $14. Where has the other $1 gone from the original $15?
4) If 9 boys fix 9 toys in 9 minutes, how long will it take 10 boys to fix 20 toys?
5) It's almost Maverick's birthday and eight of his friends are buying him a birthday present, each contributing the same amount of money. Two other friends find out about the plan and join in, agreeing to pay their share of the gift's cost. This results in a savings of $3 for each of the original eight friends. How much does Maverick's birthday present cost?
What Am I? Riddles
1) I run but I don't walk. I tell you something but I don't talk. What am I?
2) A breeze is my enemy. If I am lean, I die sooner; if thick, I live longer, yet my life is limited as I work and become diminished. What am I?
3) The more you have of me, the less you see. What am I?
4) Say my name and I disappear. Who am I?
5) I always run but never walk;
often murmur, never talk;
have a bed but never sleep;
have a mouth but never eat.
