His family consists of him and his brother, and their parents, his aunt and uncle on his Dad's side, their two sons, his aunt and uncle on his mom's side and their two daughters. He knows that his mom will only forwards emails to her husband and her kids. He knows his dad will only send emails to his brother, John's uncle, and he never forwards them to anyone. His aunt on his dad's side will forward emails to her kids and her husband and their youngest boy will always send them to his mom. The oldest cousin on his Dad's side will always forward them to his younger brother and John's brother and likewise John's Brother will send them to him. John's Aunt on his mom's side always sends them to her sister (John's mom) and her husband. John's two cousins on his mom's side and their father always share every email they get with each other. Who should John send his one email to so that everyone in his family will see it?
Hint
Draw a diagram.Answer
John should send it to his aunt on his mom's side. She will send it to her husband and John's mom. John's uncle will share it with their daughters and John's mom will send it to John's brother and John's Dad. John's brother will send it to the cousin on his Dad's side who will send it to his younger brother who will send it to his mom who will send it to her husband who would have already received it from John's Dad, but that's ok (redundancy is allowed).Hide Hint Show Hint Hide Answer Show Answer
