Welcome to another mind-bending puzzle! Picture this: Three Married Couples find themselves on one side of a river, and they all need to cross to the other side. Seems straightforward, right? Not quite. There's a catch - they have only one boat that can carry two people at a time. To make things more complicated, one of the wives is a bit, well, jealous. She cannot be left alone with any other man (besides her husband) on either side of the river. Can you help these couples navigate this tricky situation?

We have Three Married Couples (A, B, and C), each consisting of a Husband and Wife.

There's a small boat that can carry two people at most.

The Rules:

The boat must always be operated by one or two people.

No woman should be left alone with a man who is not her husband, unless her husband is present.

Your Challenge:

Your mission, should you choose to accept it, is to figure out how these three couples can cross the river without breaking any rules. Can you make it happen?

Solution:

Let the 3 couples have worn Green, Red, and Blue dresses. So, there should be Green Wife and Green Husband, red wife and Red Husband, Blue Wife, and Blue Husband.

Step 1: Green couple will go to the hotel side and Green Husband will return with the boat. (2 moves)

Step 2: Now Red Wife and Blue Wife will go to the hotel side and Red Wife will return with the boat. (2 moves)

Step 3: Green Husband and Blue Husband will go to the hotel side and Blue couple will return with the boat. (2 moves)

Step 4: Red Husband and Blue Husband will go to the hotel side and Green Wife will return with the boat. (2 moves)

Step 5: Red Wife and Blue Wife will go to the hotel side and Blue Wife will return with the boat. (2 moves)

Step 6: Finally, blue wife and red wife will go the hotel side. (1 move)

So, there will be a total of 11 steps.
