BosGuy brain teaser

riddle, exercise for your brain

Each Friday morning I post a riddle to get you to think outside the box and exercise your brain. If you are stumped, share it with a friend or colleague and see if you can figure out the answer together.

This week’s brain teaser:  I am four times as old as my daughter. In 20 years time I shall be twice as old as her. How old are we now?

Leave your best guess below as a comment, and I’ll approve the answers later. This is a tough one so don’t get discouraged!

  2. Parent is 40, Daughter is 10


  3. She’s 10, he’s 40


  4. i am 40 and she is 10


  5. She’s 10, so you’re 40; in 20 years she will be 30 and you will be 60


  6. A = 4D
    A+20 = 2(D+20)

    So, A = 40 and D = 10 !
