Riddle: Two girls have the same parents and were born at the same hour of the same day of the same month, but they are not twins. How can this be possible?
The answer of this riddle is that they were not born in the same year. It may be difficult to understand when you first hear it, but it is actually a very easy riddle to answer. When we know that the two girls have the same parents, we think that the girls are siblings.
Then we learn that they were born at the same hour of the day of the same month, which makes us believe that the two girls are twins. However, the riddle says they are not twins. In the present case, we take into consideration that the girls were not born in the same year.
Answer: They were not born in the same year.
