Questions: Suppose Aa Bb Cc are going to cross a river with only one boat. Where A means a boy and a means his GF. And similarly Bb and cc too. All of them know how to drive the boat. The boat can carry at most 2 persons at a time. How do they cross the river. Conditions: If a girl is in the different side that of her BF, she will be kissed by the other boys even if they are with their GFs. Here is the answer for this one. First Aa go to the other side of the river. Then, only A comes back leaving his gf alone on the other side. Then Bb take the boat and go to the other side. After Bb take off the boat, a takes the boat and go back to where she was originally. Then AC, two guys, take the boat and go to the other side. On returning, b takes the boat leaving all three guys on one side and all three girls on the other side. Then any two girls, say a and c, take the boat and go to the other side. While returning B takes the boat and goes to the other side to meet his gf b. Then Bb take the boat and go to the other side to join the other two pair. Unlucky guys--did not get the chance to kiss any ladies.
