Mathematics Riddle

A mother is 21 years older to her son. Six years later, the mother will be 5 times the age of her son.

Tell me what is the father of the said child doing now?

For all of you professors and teachers, just a FYI – this is total mathematics! It’s simply 2 equations to resolve 2 variables denoting the ages of the mother and the child.

Please don’t let your hatred for mathematics bar you from solving this one, IT’S FUN!

  1. Let x be the age of the son and y the age of the mother.
    in 6 years
    so x+21+6=5x
    x=27/4= 6.75
    since the son is almost 7 years old. So, probably the father is asking why his son isn’t at school right now πŸ™‚


    1. I’ll have to say you are wrong! We’ll wait till tomorrow to give everyone else a fair chance and then I’ll announce the correct answer if someone hasn’t already figured it out! πŸ˜€


  2. Shit! Shit! Shit! I’ve just spent 20 minutes trying to work this bugger out with ill-remembered algebraic equations. I was resorting to tables, nearly at voodoo, guessing that pop was either dead or serving time. And they were all wrong. This explains so much of why I dropped maths after ‘O’ grade. Bizarre though that I still wanted to have a go! Thanks it was fun while it lasted. Maybe I could reblog too and find out what sort of mathematical wonders are following me. As long as they don’t cheat. Cos then I’d have to unfollow them. πŸ™‚ I love these sorts of things although, generally, it’s lateral thinking ones I go for rather than maths. You can see why! πŸ™‚ x

  3. Reblogged this on scottishmomus and commented:
    Right, if I can get this wrong without cheating, so can you. Admission first. I’m fascinated by problems and riddles. But pretty crap at algebra. I would like to know what sort of mathematical ‘geniuses’ are following me. Or, better yet, how honest are you? No peeking at the blog hoster. Or, if you do, own up. I was off by x and y and 5xx and 21 +/-6.
    There’s a reason I gave up after ‘O’ grade maths! Language is deffo more my forte. Sorry, deffo?! You know what I mean. Thinking caps on.

  4. Btw. Slight side. I was sure I was following you. And I’ve moved to reader rather than email for the most part. I am now curious as to why follow + appeared above your page. A whole other riddle and one where I must face the prospect of going into the admin page and working out what’s going on. Who else am I missing? What does it all mean? And does WP have an equation for it all to make it easier? But if they do, I’ll send it to Noah to work it out. πŸ™‚ x
