A chicken a fox a grain. There is one boat and they all have to travel from one side to the other. You can not let the chicken eat the grain or the fox eat the chicken and u have to take them over one by one. Easy right ?
Kill the fox and the chicken and then take them over one by one, then nothing would get eaten. PROBLEM SOLVED
Some people.. Let the chicken eat the grain. Let the wolf eat the chicken. Take the wolf over. Go home. Wait till the wolf takes a crap. Scoop the crap into a pot and cook it. TASTES LIKE CHICKEN RIGHT?
Put the chicken in a sack. Bring fox and grain with you. You get to the other side in one trip. Everyone's alive.
he takes the chicken to the other side then takes the fox then puts the chicken back on the boat and takes it back then swaps the chicken for the grain and takes the grain over then goes back and gets the chicken BOOM!
