In this video I will walk you through the solution to the following problem:

Laura, Anton and Hila have spent the entire weekend coding for a new project. Between them they have drunk 54 cans of energy drink.

They each have their own empty cans on their desks. Laura passes a quarter of her cans to Anton. Anton then passes half of his current cans to Hila. Hila passes a third of the total cans she now has to Laura.

They each now have 18 cans. How many cans did each person drink?

This is actually an example problem for an entry exam of a coding course. So if you like this type of problem, maybe you have a future in programming?
