Question

A maharaja owned a mango tree that had very sweet, abundantfruit. People would come from miles around to
pick the fruit. So the maharaja decided to
protect the tree by erecting a series of seven concentric fences around it. Each fence had a gate with a guard. To get to
the tree a person would have had to pass through seven gates and pass seven guards. One day, a man approached the guard at the
first gate and said, "If you let me pass, when I come back I'll
bring you some mangoes. I will give you half of the
mangoes I have, but you must give me one back." For example, if he brings back 10 mangoes, he'll give five to the guard and the guard will give one back. The guard let the man in through the gate, and the man proceeded to make
the same deal with the other six guards.
The question is: How many mangoes did the man have to get to pass back through the seven gates, giving half to each guard and the guard giving one back and still having 5 mangoes for him in the end.
