Riddle Me This |
Description: You put up Two or Three riddles each
one with a description of a small prize attached, the
instructions are that the first person to get you the
answer wins the prize and if no one gets the correct
answer by the final date the prize goes to the person
with the closest guess! A few questions I used for this,
"You have 10 wallets and inside each wallet are 10
coins, and each coin weights 10 grams, but there is a
problem, one of the wallets contains fake coins, each of
the fake coins weights 11 grams a piece, you have one
digital scale, it takes one reading then breaks, how do
you figure out which wallet has the fake coins?"
The answer to this riddle is, "You number the
wallets, one though 10, then you take one coin out of
the first wallet, two from wallet number 2, three from
the third one and so on till you take 10 coins out of
the tenth wallet. Now assume that all the coins are
real, if you place them on the scale it will read 500g
now assume that the coins in the first wallet are fake,
so you have one fake coin in your stack of coins, this
weights 501g if you assume that the coins in the second
wallet are fake, you get 502g and so on. so the last
number tells you which wallet has the fake coins."
you can use other riddles to fill out the rest of your
board.
Instructions/Things Needed: Just a lot of riddles
with little prizes, and paper, and staples and all that
happy fun good stuff....
