Riddle:

A group of campers have been on vacation so long, that they've forgotten the day of the week. The following conversation ensues.


Darryl: What's the day? I dont think it is Thursday, Friday or Saturday.


Tracy: Well that doesn't narrow it down much. Yesterday was Sunday.


Melissa: Yesterday wasn't Sunday, tomorrow is Sunday.


Ben: The day after tomorrow is Saturday.


Adrienne: The day before yesterday was Thursday.


Susie: Tomorrow is Saturday.


David: I know that the day after tomorrow is not Friday.


If only one person's statement is true, what day of the week is it?

Answer:

It is Wednesday. If it was any other day of the week, more than one statement would be true. To solve the riddle, evaluate each person's statement and write down what day it could be according to the statement. David's statement indicates it could be any day of the week except for Wednesday. When you list the days that it could be according to everyone's statement, it turns out Wednesday is the day mentioned only one time. Darryl: Sunday, Monday, Tuesday, or Wednesday Tracy: Monday Melissa: Saturday Ben: Thursday Adrienne: Saturday Susie: Friday David: Sunday, Monday, Tuesday, Thursday, Friday or Saturday

Riddle:

A man is walking down a road with a basket of eggs. As he is walking he meets someone who buys one-half of his eggs plus one-half of an egg. He walks a little further and meets another person who buys one-half of his eggs plus one-half of an egg. After proceeding further he meets another person who buys one-half of his eggs plus one half an egg. At this point he has sold all of his eggs, and he never broke an egg. How many eggs did the man have to start with?

Answer:

7 eggs. The first person bought one half of his eggs plus one half an egg (3 1/2 + 1/2 = 4 eggs) This left him 3 eggs. The second person bought one-half of his eggs plus one half an egg, (1 1/2 + 1/2 = 2 eggs) leaving the man 1 egg. The last person bought one-half of his eggs plus one-half an egg, (1/2 + 1/2 = 1 egg) leaving no eggs.
