20+5+5 5-2 2+20 x 5 = 110 or 102 depending on where the brackets should be on the last line. I will go for 110. Sure this will be wrong as it wouldn't be getting asked if it was this easy. Title: Re: the answer is........ Post by: bagel on June 18, 2016, 12:11:32 PM worked it out same way as arbboy, but then noticed blue flowers have different numbers of petals, also yellow flowers are different.
no idea how to solve it. Title: Re: the answer is........ Post by: arbboy on June 18, 2016, 12:14:34 PM Yes didn't see any of those subtle differences. Scrap my answer then. What a pointless puzzle.
I assume that makes each petal worth 1 on the blue flower so the bottom line would be 4 for the blue flower and the single yellow flower would be worth half of the double yellow flower so 1. Therefore the bottom line would be 1+20 x 4 = 84 or 81 right? Title: Re: the answer is........ Post by: mondatoo on June 18, 2016, 12:45:25 PM The top line is red + red + red or red + orange + orange ?

Title: Re: the answer is........ Post by: hector62 on June 18, 2016, 12:55:09 PM I'll try 81.

No chance, Arbboy would never be results orientated like that. Title: Re: the answer is........ Post by: AdamM on June 18, 2016, 03:45:47 PM Yes didn't see any of those subtle differences.

Post by: bergeroo on June 18, 2016, 05:31:58 PM 84?
20+20+20 20+5+5 5-2 1+20x4 = 82 Title: Re: the answer is........ Post by: doubleup on June 18, 2016, 05:35:42 PM I think some are assuming that the graphics are deliberate and not just a cock-up.
The only answer that is valid imo is a picture of 20 of the four petalled flowers and one of the yellow flower. Title: Re: the answer is........

Post by: david3103 on June 18, 2016, 07:26:55 PM oops! 84 I mean! 1 + 20x5 = 81 BODMAS rules. Brackets, Of(powers), Division, Multiplication, Addition, Subtraction Not sure what the official answer is btw, just sure of the result of 1 + 20x5 Title: Re: the answer is........ Post by: WotRTheChances on June 18, 2016, 07:44:14 PM I saw this a while back on Facebook.
It's just unsolvable without making a series of assumptions, which it's impossible to say if they are correct. Not sure if you can say because the 5 petal blue flower has a value of 5 that each petal = 1 thus the 4 petal flower = 4. It's plausable and somewhat logical, but not a definite solution. Similarly with the double yellow flower symbol... it could be [yellow flower]*[yellow flower], or it could have a value of 2*[yellow flower], or it could be an entirely distinct symbol. Making best-guess assumptions, my solution would be 1+20*4 = 81, but the mathematician in me says it's just unsolvable (his name is Bruce) Title: Re: the answer is........

Post by: winkie on June 19, 2016, 08:45:03 PM obv answer is... 102
