OK... If you figure out the answer, then you may want to argue about some things. What if the kid's early/late? isn't it 10 months and not 9?, etc... This question is fun/interesting, but not technically correct in a lot of ways. Despite enjoying multiple answers to questions, I don't really like hearing a lot of complaints about such questions. This one is for fun, not fact.
Sorry about that. I know that the people reading this blog usually don't complain about things like this, but I thought I should head it off.
I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!

Daddy's a deadbeat
ReplyDeleteOh.. the kids age is 3.75 but i don't know anything about the father... i still think he is a deadbeat though =p
ReplyDeleteIf you do the math, then the baby is -9 months old, meaning he is being conceived now. I think we know where that puts the father.
ReplyDeleteLet X be Mom's age and Y be the child's age.
ReplyDelete1) X = Y + 21.
2) X + 6 = 5*(Y+6) -> X = 5Y + 24
Solve for X and Y and you get Y = -3/4 or about 9 months before birth. So, now you know dad is with mom!
