This riddle has been around for some time on internet platforms such as Instagram, Facebook, and WhatsApp, and many people still argue over what the answer might be, as there are many possibilities.

Or let: Man = M Fox = F Chicken1 = C1 Chicken2 = C2 This is how they cross the river: M,F → ← M M,C1 → ← M,F M,C2 → ← M M,F →
