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 day is it? I don’t 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 their statement.
The list of possible days based on each person’s statement are:
Darryl: Sunday, Monday, Tuesday, or Wednesday.
Tracy: Monday
Melissa: Saturday
Ben: Thursday
Adrienne: Saturday
Susie: Friday
David: Sunday, Monday, Tuesday, Thursday, Friday or Saturday
As you can see, it turns out that Wednesday is the only day that was mentioned only once.
