In 1991, a devastating flood ravaged many districts of Bihar. A group of villagers found itself confronted by a wide and deep flood water. However, they found two children who were rowing a boat. But the boat was so small that it can only carry either the 2 children, or 1 adult person and it can be rowed by single child or adult. Can the 246 villagers move across the flood water? If yes, what is the minimum number of movements that the boat has to make from shore to shore?

Answer:
At least 984 movements are required.
Step-by-step explanation:
The two children move the boat to the opposite shore. One gets out and the other child brings the boat back. One villager rows across; villager gets out, and the child returns with boat.
Thus, it takes 4 movements to get 1 person across and bring the boat back. Hence it takes 4*246 = 984 movements, to get the the entire group of villagers across the flood water.
