Pareto's principle, also known as the "80/20 rule", states that in many situations of results come from
of (the most important) causes. For instance, Microsoft found that, by fixing
of most commonly reported bugs, they would eliminate
of downtime in their systems. In the business world, it is often said that
of income comes from
of the most important clients. In the world of mobile games, when it comes to games with free basic functionality,
of profit comes from
of players. Some say that
of your success will come from
of your activities.
It is a known fact that of the world's goods is owned by
of (the richest) people. Your task is to check the validity of this rule based on the bank accounts owned by clients of a single bank. Is it true that
of accounts hold
of the total money? Does a stronger claim hold, for instance, that only
of accounts hold
of the total money?
More precisely: based on the given account balances of bank clients, your task is to find numbers
and
with the maximal difference
such that we can say that precisely
of accounts hold
of the total money of all clients of the bank.
