There's a thread on /pol/ right now with almost 100 replies of everyone arguing about this image

Can sci solve this?

Can someone answer an actual /sci/ question and tell me what part of human thought process makes these so popular?

I mean get that people like to "see how smart I am, I got it right" but most of us have grown up a world where we see actual hard maths problems, and posting one on Facebook would get absolutely no interest.

drinks sizes are different
less fries in bottom row.
either 6 variables in 4 equations
or
appeal to common sense:
3x=30
(percentage difference in sizes of drinks)*x + 2y=20
y +2z=9
y+ z/(number of fries in containers in second row)*(number of fries in containers in third row)*x=w

4 variables 4 equations in the second case

the most cringe are those where a math expression without parentheses is shown, e.g.
1+2x3-4:5
and most people will answer 1 because that's what you'd get if you ignore priorities of x and : over + and -, a few people will be called dumbasses for asnwering some silly fraction like 31/5, and finally my phys teacher will answer 1.429829E45 getting no lulz whatsoever

Drink = 10
Burger = 5
Fries = 2

thus, the equation is:

5+2*10=x

solving for x gives

x = 25

also, /pol/ is utterly retarded.

Because the average person wouldn't even know where to begin to try and solve such a problem. You see problems like these pop up from time to time, where the initial part is easy but the last part, involving multiplication, yields a variety of different answers based upon which order you apply the operators in.

>soda x3 = 30, soda = 10
>soda x1 + burger x2 = 20, burger = 5
>burger x1 + fries x4 = 9, fries = 1
>burger + fries x soda = ?
>5 + 1 x 10 = ?
So
>5 + (1 x 10) = 15

I guess people like these sort of questions because they're relatively easy and the amount of people that get it wrong gives them a sense of superiority over their fellow man.

[Anonymous No.10052579]

>>10051382
And I forgot to do order of operations so it's not 60, it's 15.

[Anonymous No.10053077]

stop spamming this thread
or at least post the /sci/ version

[Anonymous No.10053101]

if the sum of three drinks equals 30, then one drink has to equal 10.

Since 20-10=10, then two burgers equals 10 meaning that one burger equals 5.

Since 9-5=4, then two fries plus two fries equals 4.

In the third image, however, since there is only one fry we can conclude that it is only one. Therefore, the last expression reads:

>5 + 1 * 10=

If we use PEMDAS, we find that the answer is 15.

[Anonymous No.10053119]

>>10051382
it's 15, unless you're so irreparably autistic that you try and vouch for the argument that the two fries and 1 set of fries are completely different variables with no relation to each other

IQ of 98, by the way.

[Anonymous No.10053226]

>>10051382
Drink = 10
burger = 5
5 + (fries)^2 + (fries)^2 = 9 (they're next to each other so they're clearly being multiplied)
2(fries)^2 = 4
(fries)^2 = 2
so fries = ±√2

the final expression then equals 5±10√2

[Anonymous No.10053250]

Its unsolvable because you cant prove that the 1 set of fries symbol is half of the 2 sets of fries symbol.

you realize there are 4 packages fries there right?

5+2+2=9

[Anonymous No.10055775]

>>10051382
Wait, if soda, burger and fries are x, y, z, then we could say that

3x = 30
x+2y=20
y+2z=9

Using a kramer matrix I get the results

x(soda)= 10
y(burger)=5
z(fries)=2

So one burger, one fries, and one soda equals 17

Soda is 10 each
Burgers are 5
Fries are 1
Burger + Fries * Soda =?
Notice the fries from the line above and the line in the unsolved equation are different and the unsolved equation fries are missing one.

Thsoe fries are worth 6/7
So 5 + (6/7) * 10 is 13.57 following PEMDAS/BEDMAS
