ah ... I love the puzzles you send ... I know this from earlier too. There are multiple answers depending on how we perceive the questions. I will go with 21 7 men, one wife each (7) each couple one child (7) so, 7 + 7 + 7 = 21
Spoiler: Click Me! I don't know the answer. I believe there is lot of ambiguity and can be taken anyway we want. 7 men have 7 wives. I guess we can call them 7 couples as there is no "each" in this statement. Each man and each wife have 7 children could be equated to each couple having 7 children. Or could it? What if one man had two wives and a wife had two husbands. Setting it aside, lets say it is in fact 7 couples as the legal system doesn't allow more than one spouse and ex-wife will not be considered wife. Now comes the bigger ambiguity where we have to count the number of people. Are any of the men or wife also a child among the 7 couples. Leaving aside that, if each couple had 7 children, it is 7 men, 7 wives, 7 children for each couple ( 49 children in total ). Total number of people is 7 + 7 + 49 = 63
Great Grand father & Great Grand mother - 2 people+6 children = 8 Grandfather & Grand mother - 2 people+6 children = 8 Father & Mother - 2 people + 6 children = 8 Son & wife - 2 people+7 children= 9 Son & wife - 2 people+ 7 children =9 Son & wife - 2 people+7 children = 9 Son & wife - 2 people + 7 children = 9 Total = 60
