A Series of Middle-Grade Mystery Novels by John Madormo
Brain Teasers!
Charlie here. Charlie Collier, Snoop for Hire, that is. I can't begin to tell you how many hundreds of brain teasers I've solved in my time. It might have been a riddle that Henry tries to stump me with at lunch in the cafeteria...or a science brain buster that Mrs. Jansen poses in class...or a real brain wobbler that presents itself in the midst of a full-blown investigation. Whatever the circumstances, I'm ready. I just call upon my amazing deductive reasoning skills, and in no time, the problem's solved.
Do you think you have what it takes to become a real private eye? You think so, huh? Okay, let's find out. Here are a few of my favorite brain teasers. See how you do.
1) There are three houses. One is red, one is blue, and one is white. If the red house is to
the left of the house in the middle, and the blue house is to the right of the house in the middle, where is the white house?
2) I exist only when there is light, but direct light kills me. What am I?
3) Where's the only place on Earth where Friday comes before Thursday?
4) How many months have 28 days?
5) If four peacocks lay four eggs in four days, how many can one peacock lay in eight
days?
6) How much dirt is there in a hole that is four feet deep with a diameter of three feet?
7) Why are round manhole covers safer than square ones?
8) A rope ladder hangs over the side of a boat and just barely touches the water. The
rungs of the ladder are six inches apart. If the tide rises three feet, how many rungs will
be under water?
9) How many times can you subtract the number 5 from the number 100?
10) If June equals 50, and July equals 68, then what would August equal?
