Puzzle 2: Think and Solve

Solution: Suppose A and B are two banks of the river. Hari is at point A and wants to go at point B.
1.      First of all, Pushpa and his son Anuj cross the river to point B.
50 kg + 25 kg = 75 kg < 80 kg
2.      Pushpa leaves Anuj at point B and goes to point A where Hari is waiting.
50 kg < 80 kg
3.      Pushpa stays at point A and Hari alone crosses the river to point B.
70 kg < 80 kg
4.      Now, Hari stays at point B and sends Anuj alone to point A to take Pushpa.
25 kg < 80 kg
5.      And finally Pushpa and Anuj cross the river.
50 kg + 25 kg < 80 kg

Thus, they finally cross the river safely.
