Five men are employed for strawberry picking. They all don't pick strawberries at the same speed. They pick in the ratio of 1::2:3-4:5. That is, the second man picks 2 times as many strawberries as the
first in the same amount of time, and the 3rd man picks 3 times as many strawberries as the first, and so
on. To compensate for this, their manager makes the slower men work for more time. In fact, he makes
them spend time in the ratio 5 :: 4 :: 3 :: 2 :: 1. That is, the first man works 5 times longer than the 5th
man, and so on. At the end of the day, the manager realizes that they have not all picked the same
amount of strawberries. Two men have picked 250 strawberies each. Two other men have picked more
then these two. And one man has picked the maximum - more than anyone else. How many
strawberries did this man pick?
