**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.
