A man was killed on Sunday morning. His wife found the body and called
the police. The police arrived and questioned the chef, maid, butler,
and gardener. Their alibis were:
Chef - making breakfast
Maid - getting mail
Butler - setting table
Gardener - watering plants
The police immediately arrested the criminal. Who was it and how did they know?
The maid. Mail isn't delivered on Sunday
I was visiting a friend one evening and remembered that he had
three daughters. I asked him how old they were. "The product of their
ages is 72," he answered. Quizzically, I asked, "Is there anything else
you can tell me?" "Yes," he replied, "the sum of their ages is equal
to the number of my house." I stepped outside to see what the house
number was. Upon returning inside, I said to my host, "I'm sorry, but I
still can't figure out their ages." He responded apologetically,
"I'm sorry, I forgot to mention that my oldest daughter likes strawberry
shortcake." With this information, I was able to determine all three
of their ages. How old is each daughter?
3, 3, and 8. The only groups of 3 factors of 72 to have non-unique sums
are 2, 6, 6 and 3, 3, 8 (with a sum of 14). The rest have unique sums:
2 + 2 + 18 = 22
2 + 3 + 12 = 18
2 + 4 + 9 = 15
3 + 4 + 6 = 13
The house number alone would have identified any of these groups. Since more information was required, we know the sum left the answer unknown. The presence of a single oldest child eliminates 2,6,6, leaving 3,3,8.
Einstein said that only 2% of the world could solve this problem.
There are 5 houses in 5 different colors. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.
Who owns the fish?
The person in house 4 owns the fish. The situation looks like this:
