A Tiger, A Goat & A Bundle Of Grass

A man is walking down the village road with a tiger, a goat and a bundle of grass. Soon he arrives at the river bank where there is one tiny boat that can carry him and another animal or grass at a time. 

Here is the problem: Left alone, the tiger will eat the goat. And similarly, the goat will eat the grass bundle. How is he going to take all three across the river safely?

Cross The River

What should he do? 

Crossing a river with tiger, goat and grass

What is situation?

1. First he need to carry a goat across the river. Tiger won't eat a bundle of grass.

2. Then he should take a tiger (or a grass bundle) across the river.

 3. And get goat again back with him.

  4. Now he should leave a goat behind & take a grass bundle (or a tiger) with him across the river.

  
5. Finally he has to take the goat across the river in last round.
