I agree with Thomas (109) because: Line 1: each measuring cup = 10 Line 2: each cookie (cooked or not) = 1 Line 3: subtract cup (10) and 12 cookies (12) from both sides: wooden spoon (?) = 5 Line 4: spoon (5) + cup (10) + 1 cookie = 16 Line 5: 9 cookies (9) + cup (10) × 2 spoons (10) = 9+10×10 = 109. If left-to-right math is used ("chain mode"), you get 190. <0|ɸ|0> -Joe- |

RE: another puzzle
Aha, I didn't notice that there were varying amounts of cookies on the trays, I thought 'tray of cookies' was a unit. Which made the puzzle silly.
Should have known... and it's rare that I miss details that involve cookies. --Bob Prosperi |

RE: another puzzle
Maybe it's just a coincidence, but I've seen several puzzles like this lately, always involving some detail that turns out you have to count, like the cookies in this one. This one was a bit less sneaky than some of the others, in that the fourth equation provides a hint that something is up. If "tray of cookies" were a unit by itself then that fourth equation would be redundant...

Thomas, I've got to hand it to you, you are da' man! I thought 112 like Bob (and my sister-in-law). She couldn't figure out why the girl that guessed 109 was the winner, neither could I until I saw your post and explanation (and Joe too).
You've got to pay attention to the details. |

Yes, I looked and looked at the 4th line, and finally concluded it was simply extraneous info intended to distract; cookies will do that. Nowhere was it said that all information was necessary, although it's typically assumed to be so in these puzzles. --Bob Prosperi |

RE: another puzzle
Also got 112 like most others here, but for some reason those cookie trays looked like pills and the stirrer a toothbrush, so well I didn't even notice it as a tray of cookies until that was pointed out!
Still if that was the way they're playing it, why is the single cookie not on a tray...selective visualization, I call foul! ![]() |

But it looks like a chocolate chip or oatmeal raisin cookie! Surely you must make allowances for those yummy Bastions of Biscuitness! Tom L Cui bono? |

RE: another puzzle
OT: I recently took the UK's amateur radio exams; there, it's common for them to put in a bit of extraneous detail, not needed to answer the question, deliberately to lead you astray.
Or, as they would no doubt put it, to make sure you understood it correctly ![]() Cambridge, UK 41CL/DM41X 12/15C/16C DM15/16 71B 17B/BII/bII+ 28S 42S/DM42 32SII 48GX 50g 35s 30b/WP34S Prime G2 & Casios, Rockwell 18R :) |
