Логическа задача

[papito]

Здравейте, някой може ли да обясни накратко как трябва да се подходи и да се реши тази логическа задача, която ми се падна преди време на котролна работа? Много време я мислех и умувах, но така и не можах да стигна до даденото решение. Ето това е условието на задачката:

Ed, Frank, George, and Harry took their wives to the Country Club dance one Saturday evening not long ago. At one time as a result of exchanging dances Betty was dancing with Ed, Alice was dancing with Carol's husband, Dorothy was dancing with Alice's husband, Frank was dancing with George's wife, and George was dancing with Ed's wife. What is the name of each men's wife, and with whom was each man dancing?

А това е даденото решение:

Скрит текст: покажи

Alice, Betty, Carol and Dorothy are married to George, Harry, Frank and Ed respectively, and were dancing with Frank, Ed, Harry and George, respectively.

Никой ли не може да я реши приятели?

Здравей,

"George was dancing with Ed's wife" => Ед не танцува с жена си.
" Betty was dancing with Ed" => Бети не е жена на Ед. "Alice was dancing with Carol's husband, Dorothy was dancing with Alice's husband" =>Ед не е мъж на Карол. нито на Алис => Ед е женен за Дороти.

"George was dancing with Ed's wife"=>Джордж танцува с Дороти
"Dorothy was dancing with Alice's husband" =>Джордж е мъж на Алис.

"Frank was dancing with George's wife"=>Франк танцува с Алис
"Alice was dancing with Carol's husband" =>Франк е мъж на Карол

Остават Хари и Бети, който са последната двойка женени
