You have a thousand Re. 1 coins with you. You have ten bags with you and you can put any number of coins in each of the bags.

How will you do it?

Alex is stranded on an island covered in forest.
One day, when the wind is blowing from the west, lightning strikes the west end of the island and sets fire to the forest. The fire is very violent, burning everything in its path, and without intervention the fire will burn the whole island, killing the man in the process.
