Using math to solve daily problem!
Math Problems Solving: A peasant wants to sell his stuff and get some salt and other supply back home. However, he has to cross a river with a small boat. How can you help him carry a sheep, wolf as well as cabbage across the river? You can only carry one item across at one time.
Math problem solving: Hint, Remember, sheep eat cabbage, wolf eat sheep.
That us solve and analysis it together.
1) Carry the sheep first across and leave wolf and cabbage behind, because we know wolf does not eat cabbage.
2) Go back and get the wolf and leave only cabbage behind. Then come back with the sheep in the boat, so it is not eaten by the wolf. I know it takes a lot of effort.
3) Put sheep back and get the cabbage. Leave the cabbage with the wolf, and it won’t touch it!
4) Get the sheep across!!
We are successful!!
