BMAD Posted November 28, 2017 Report Share Posted November 28, 2017 There was a flock of ducks flying in the sky. One ahead of the other two; one behind of the other two; one between the other two, and three in a row. How many ducks were flying? Quote Link to comment Share on other sites More sharing options...

(To fit the given conditions all must be in a row with no two beside each other.) Quote Link to comment Share on other sites More sharing options...
