There is a family gone on a picnic on one of the sides of the river. The family includes Mother, Father, two of their sons, two of their daughters, a servant and their pet dog named Tommy. In order to go to the other side of the river they need to cross the river. Since the bridge is broken, the only way they can cross the river is through the boat.
There is a condition with the boat. Only two persons can go on the boat at a time (considering Tommy as one person)
The other problems that they face are:
1. The servant can’t leave Tommy with the rest of the family or it would bite them.
2. They can’t leave father with daughters without mother.
3. In same way Mother can’t be left with sons without father
Also an adult is needed to drive the boat and it can’t drive by itself.
How will they reach the other side of the river ?
