Midnightmom Posted December 20, 2016 Share Posted December 20, 2016 Can you solve this puzzle? It will not only test your math acuity, but also your powers of observation. (Image attached. It doesn't really work as a "quiz" if I have to describe the graphic.) Quote Link to post

Jeepers Posted December 20, 2016 Share Posted December 20, 2016 I know I got it. I've seen similar ones and know how to do them. Great learning tool for reasoning out an answer. Quote Link to post

Mt_Rider Posted December 24, 2016 Share Posted December 24, 2016 3 cups of soda = 30 .......so each Soda = 10 soda (10) + burger + burger = 20 ........so subtract what you know ( 20 minus the 10 of the soda) leaves 10 left. So each burger is half of 10 then, ....Burger = 5 Burger (5) + two fries = 9 .....so subtract the burger (9 minus the 5 of the burger) leaves 4......so each fry is half of 4 ...... Fries = 2 Burger (5) + Fry (2) + Soda (10) = ......... 17 MtRider .....who is verrrrry bad with numbers but unless I'm not understanding the point, this is pure logic.....isn't it?

Mt_Rider Posted December 24, 2016 Share Posted December 24, 2016 Aaaaaaaauuuuuuggh! I kept wondering how Wormie got SEVENTY? Then caught my error..... Burger (5) + Fry (2) ......TIMES Soda (10) ........ equals 70 Details.....why I am not a mathematician. :grinning-smiley-044: Got the logic but ...... MtRider ...I'm tired now.... Quote Link to post

Good reasoning, and..................mostly correct. In the third line the fries do indeed work out to being $2. HOWEVER, that is the value for 2 servings of fries! In the final line there is only a single serving................so $1. Next, the recognition of the multiplication sign in the final line changes the equation from the previous lines having been all addition...so good catch there. Let's look at the final line numerically: $5 + $1 x $10 = ? Lets use the mathematical law of PEMDAS to solve this: There are no parantheses. There are no exponents. Multiplication is next in line. So one single fries ($1) times one soda ($10) equals $10. No division to worry about. Addition is next. So the equation now becomes one hamburger ($5) plus the previous calculation ($10). No subtraction in this puzzle. Rewritten..............$5 + ($1 x $10) or $5 + $10 = $? Answer.......................$15 Merry Christmas! Now you can enjoy your day without worrying about this any more. Quote Link to post

Mt_Rider Posted December 25, 2016 Share Posted December 25, 2016 I was with you as far as the theory about the fries.....which I disagree with. Burger (5) + two fries = 9 .....so subtract the burger (9 minus the 5 of the burger) leaves 4......so each fry is half of 4 ...... Fries = 2 If the burger is 5 ....that leaves FOUR for TWO FRIES.........which is 2 for EACH FRY. 5 + 2 + 2 = 9 I have not seen anything that makes that false. And you completely lost me on the rest of what you said. MtRider ....not a mathematician.... Quote Link to post

Jeepers Posted December 26, 2016 Share Posted December 26, 2016 (edited) I get: burger (5) + fry (1 order) = 6 x drink (10) = 60 Edited to add: pay no attention to my previous post. Perhaps I didn't have the correct answer after all. Could the internet have lied to me? Surly not. It's the internet! But I really do know how to make change. Honest.

Mt_Rider Posted December 26, 2016 Share Posted December 26, 2016 one fry order = 2 That's my story and I'm sticking with it....... .....so far. MtRider Quote Link to post

Jeepers Posted December 26, 2016 Share Posted December 26, 2016 LOL I am sooo math challenged. But in the third picture it shows the fries as a double (large) order. A 2-pack if you will. In the last line it is a picture of one order of fries like a size small. In other words in line three the total order is for 4 single orders of fries a burger and a drink. Line just has 1 small order of fries. When I needed a math answer here I used to ask CGA (RIP). She was a whizz at it. No explaining...just gave me the answer. Quote Link to post

Mt_Rider Posted December 26, 2016 Share Posted December 26, 2016 Ahhhhh....THAT I understood, Jeepers! So as well as initially missing the TIMES sign....also missed the second set of fries in that line. Hmph! Logic fine. Observation feeble. Math....we don't wanna talk about it.

TheCG Posted January 3, 2017 Share Posted January 3, 2017 I got $25. $10 for the soda, $5 for burgers, $2 for fries. $5 + $2 X $10 Order of operations says multiply before add, so $5 + $20 $25 Quote Link to post

Midnightmom Posted January 3, 2017 Author Share Posted January 3, 2017 It just struck me that the final line of the problem is not based in reality!!! If I were actually at the store they would be overcharging me if they collected more than $16.00!!! 1 burger plus 1 single order of fries plus 1 drink $5 + $1 + $10 = $16 Let me also say..........................I would NEVER PAY $10 for a CUP of soda!!!

TheCG Posted January 3, 2017 Share Posted January 3, 2017 Let me also say..........................I would NEVER PAY $10 for a CUP of soda!!! I would like to point out that I *have* paid over $10 for a cup of soda (double that, actually), BUT only because they'd let me refill it for free all year. Quote Link to post
