In a group of 150 people, $$\frac{2}{5}$$ are men, $$\frac{1}{3}$$ are women and the rest are children. The average age of the women is $$\frac{4}{5}$$ of the average age of the men. The average age of the children is $$\frac{1}{5}$$ of the average age of the men. If the average age of the men is 50 years, then the average age of all the people in the group is:
