A Problem of Logistics

Gopal, a farmer, goes to the market to buy a rooster for his farm. After some searching, he finds a suitable one and buys it. He then purchases a bag of grain as feed for the rooster and the hens on the farm. His purchases done, he is about to leave the market when he spots a man selling a fierce-looking dog. Remembering that he needs a watchdog for the farm, he buys the dog after some bargaining. He then sets off for home, leading the dog and carrying the rooster and the bag of grain. Now, he faces a problem. To reach his village, he has to cross a river. There is a bridge, but can bear only limited weight. So, he can take only one item with him at a time. The problem is, he cannot leave the dog alone with the rooster on the bank, because the dog would probably attack the rooster and kill it. Nor can he leave the rooster with the bag of grain, because the rooster would eat up the grain! So, how can he cross the bridge and reach home with all his possessions intact?

Solution: 
Gopal formulates a foolproof plan of action. First, he takes the rooster and crosses the bridge, leaving the dog and the bag of grain on the bank. On reaching the opposite side, he leaves the rooster on the bank and returns for the dog. He takes the dog across, leaves it on the (opposite) bank and then comes back, carrying the rooster with him. Next, he leaves the rooster on this bank, picks up the bag of grain and carries it across the bridge. Leaving it near the dog on the opposite bank, he returns yet again for the rooster and makes a final trip across, carrying it! Thus, everything is safely across.
