An individual, who has a sum of $100000$ EUR, wishes to make a donation to $3$ associations so that each one has the same capital at the time of their next project. The project of the first association will take place in $5$ years, that of the second association will take place in $4$ years and that of the last association will take place in $10$ years.

How should this individual distribute his sum if he has a savings account at the rate of $8\%?$
