Bird Riddle
Twenty-seven ducks are going to the pond. Five of them got lost, thirteen of them are staying home, and nine of them are at the pond. Where are the rest of them?
Choose an answer
A.They flew south
B.They are hiding
C.They are in transit
D.There aren't any anywhere else.
Answer: There aren't any anywhere else.
5 + 13 + 9 equals exactly 27, so there are no ducks left unaccounted for despite the riddle implying there should be.
