Hours of Sleep
Adam's mom is 20% younger than her husband who is 50. If you add both their ages up, have the mom and dad spent more time sleeping (sleep is a third of your life) than Adam and his two brothers aged 14, 11 and 5 have been alive for?
Answer
20% of 50 is 10. 50-10 =4050 + 40 = 90
90/3 is 30
14 + 11 + 5 = 30 so their parents have slept the equal amount as their three children have been alive.
