ANSWERS
Question 1:
Brock has 6 pairs of green socks and 6 pairs of blue socks in his top drawer. He's not tall enough to see inside the drawer and must reach in the drawer without looking. What is the least number of socks Brock can grab to be sure he has a matching pair?
Answer 1: 3
Even if the first two are different colors, the third one will
be a match.
Question 2:
What is the next
number in this series?
O3 T3 T5 F4 F4 S3 S5 E5
N4 ___
Answer 2: T3
The letter in each pair comes from the beginning letter of that
word (One = "O", Two = "T", etc.). The number
represents the number of letters in that word (One = "3",
Two = "3", and so on).
Question 3:
Assume there are 300 million people in the U.S. For each person, take the number of fingers (including thumbs) each has on his or her left hand, and multiply it by the number of fingers on the next person's left hand. If you continued this multiplication for all 300 million people in the U.S., what would the final total number be?
Answer 3: 0
At some point you'd run across someone with no fingers on his or her
left hand, resulting in zero. Anything multiplied after that
would result in zero as well.
Question 4:
Add this column of numbers, one at a time:
|
1000
20
1030
1000
1030
20 |
Answer 4: 4100
Did you guess 5000? If you did, you're wrong. The correct answer
is 4100. The brain has a tendency to go from 4080 to 5,000 (when
it should be 4100) on the last line.
Question 5:
Glory has 6 pairs of red gloves and 6 pairs of orange gloves in her top drawer. She's not tall enough to see inside the drawer and must reach in without looking. What is the least number of gloves Glory can grab to be sure she has a matching pair?
Answer 5: 13
Gloves have a left hand and a right hand. So she might pick all
right-hand gloves the first 12 times, but on the 13th try, she'd
have to match one.
Question 6:
How many triangles are found in the pyramid?
Answer 6: 78
Question 7:
A collector showed an archaeologist five coins he had just purchased. The collector claimed:
Coin A was from 227 B.C. yet it had no date on it.
Coin B was from A.D. 870 and had that date on it.
Coin C was from 27 B.C. and had that date on it.
Coin D was from 312 B.C. yet it had no date on it.
Coin E was from A.D. 1010 yet it had no date on it.
The archaeologist told him that one of the coins was a fake. Which one?
Answer 7: C
The term B.C. would not have been known at that time, and hence
would not have been indicated in that way on the coin.
Question 8:
A scientist was well-known for having excellent vision. At a
seminar she announced to the attendees "There is something
in this room that you can see, and so can everyone else in the
room. But I cannot see it." What was it that the scientist
could not see?
Answer 8: H e r F a c e
Question 9:
Match up the folded
snowflakes with their unfolded versions.
Answer 9:
A: 6
B: 4
C: 5
D: 1
Question 10:
A scientist discovered a new type of insect that adds new insects
to its community each day. Starting with one insect on Day One,
two new insects are added on Day Two, three more are added on
Day Three, and so on. Assuming all insects survive, how many
will live in the community after 100 days?
Answer 10: 5,050
The series of numbers 1 to 100 contains 50 pairs of numbers that
add to 101. For example, 1 insect is added on Day One, and 100
insects are added on Day 100. (1+100=101) 2 insects are added
on Day Two and 99 insects are added on Day 99. (2+99=101) Continue
through Day Three and Day 98, Day Four and Day 97, etc. Eventually
you will have 50 pairs of numbers, all of which add up to 101.
Thus, 50 X 101 = 5,050.
Question 11:
What word is represented
by these words?
see are why pea tea eye

Question 12:
Only one of these sentences is true. Which one?
A) Exactly one of these 10 sentences is false.
B) Exactly two of these 10 sentences are false.
C) Exactly three of these 10 sentences are false.
D) Exactly four of these 10 sentences are false.
E) Exactly five of these 10 sentences are false.
F) Exactly six of these 10 sentences are false.
G) Exactly seven of these 10 sentences are false.
H) Exactly eight of these 10 sentences are false.
I) Exactly nine of these 10 sentences are false.
J) Exactly ten of these 10 sentences are false.
Answer 12: I
The only sentence that could possibly be true is "Exactly
nine of these 10 sentences are false." If any of the sentences
A through H were true, it would have to mean that at least one
other sentence was also true, which in this list would be impossible.
Sentence J cannot be true for the simple reason that it would
then prove itself to be false. Confused yet?
