July 23, 201610 yr comment_870776 Aunt Mary is very particular about her age. A nosy nephew asks her how old she is. She replies, 35, not counting Saturdays and Sundays. What is her real age? Report
July 23, 201610 yr Author comment_870811 Alright, so she has lived 35 years of (365-52*2) days each. That amount of days will equal q.She does not count 35 years of (52 + 52) days each. That amount of days will equal r.So our initial equation is 35q + 35r.We now expand: 35(365 - 104) + 35(104)35(261) + 35(104) And solve: 9135 + 364012775. But saying that someone is 12775 sounds nasty, rude, and is not flattering. Dividing by 365 ought to give us her age in years, which is... 35!I guess you are a maths teacher (the nice kind of maths teacher), an enthusiastic student, or someone who uses maths in their job. Your problems are awesome! Report
August 8, 201610 yr comment_874289 legoboyvdlp, the problem with your calculations is that she lived 35*365 week days, and a year is 365*(5/7) week days. So we take (35*365) / (365*(5/7)), the 365's cancel (thankfully, now we don't need to worry about leap years) and we're left with onbekende's method of 35 * (7/5). (the fraction flips to make it on top.) (I was a math Tutor in college) Report
