Six beavers need to cross a bridge but it requires three wood planks. Each beaver has two planks that can be used twice. They can lend planks to each other and have a maximum of three planks each. The beavers can cross the bridge if they work in pairs of two, using three planks per pair. This leaves three extra planks.

BEBRAS CHALLENGE: BEAVERS AND THE BROKEN BRIDGE
A group of 6 beavers want to cross a bridge, but the bridge needs 3 wood planks for being crossed. each beaver has 2 wood planks to place on the bridge. however, each wood plank can be used just twice otherwise it will break. also, the beavers can lend each other one wood plank; a beaver can have at the most just 3 wood planks. finally, there is a bucket to place the extra wood planks. TASK: Can all the beavers cross the bridge with the wood planks they have? if so, how many extra wood planks would there be? SOLUTION Yes, all the beavers can cross the bridge, and there are enough tables to do so, but the question now is how many extra wood planks are there? To begin, we must understand that the bridge requires three wood planks, and two beavers can cross the bridge with only three tables, because each table can be used twice. In other words, a couple of beavers requires only three tables, so with three couples, they will require only nine tables. Therefore, there would be 3 extra wood planks.
RELATION WITH INFORMATICS
This is a simple example of systems optimization, because even when we have a lot of extra resources to complete a task, we should try to use the fewest number of resources possible, so that we can make a simple process that is easy to read. It is also a good way to recognize how the data could be read in a different way, allowing us to come up with new and unique solutions.
