The problem:

1+4=5
2+5=12
3+6=21
8+11=?

A: [spoiler]96[/spoiler]
B: [spoiler]40[/spoiler]

I am curious because both answers work but I guess which one you go to first tells something about how you think.

Surely the plus sign should be replaced with another symbol.

To get answer A, translate x+y=C into [spoiler]x + xy = C[/spoiler]. I'm curious how to get B, but not enough to keep looking.

[spoiler]You just keep adding the numbers to get B. So 1+4(=5)+2+5(=12)+3+6(=21)+8+11=40[/spoiler]

8 + 11 = [spoiler]19[/spoiler], you morons.

I got the 96 answer really quick and even when I looked at the spoiler couldn't see where the 40 came from  :hmm:

Reflecting on CdM's comment, are all Polish arithmetic papers like this?

I guess the answer A is more of a "nerd answer", as it spots the pattern that works on its own in each equation, even if the others do not exist.

Answer B is simpler but also one for people who see the broader picture. Sort of a "humanist answer".

I picked A, like most Languishites.

There's also many others:

[spoiler]
1+(1*4)=5
2+(2*5)=12
3+(3*6)=21
8+(4*11)=52 [/spoiler]

[spoiler]
1!/0!+4*1=5
2!/1!+5*2=12
3!/2!+6*3=21
8!/3!+11*4= 6764[/spoiler]

[spoiler]
1!/0!+4*1=5
2!/1!+5*2=12
3!/2!+6*3=21
8!/3!+11*8= 6808[/spoiler]

[spoiler]
1*(four+ne)-1=5
2*(five+two)-2=12
3*(three+six)-3=21
4*(eleven+ight)-4= 36[/spoiler]

[spoiler]
1*(fur+ne)=5
2*(five+two-1)=12
3*(three+six)=21
4*(lvn+ight-1)= 24[/spoiler]

[spoiler]
1*(fur+ne)=5
2*(five+two-1)=12
3*(three+six)=21
8*(lvn+ight-1)= 48[/spoiler]

Since the mathematical expressions aren't used in their normal meaning I'm pretty sure there are innumerable different results that could be considered to "work".

HP calculators use something called reverse Polish notation.  For the longest time I thought that was simply a generic put-down aimed at Pollocks.
In Italy, for thirty years under the Borgias, they had warfare, terror, murder and bloodshed, but they produced Michelangelo, Leonardo da Vinci and the Renaissance. In Switzerland, they had brotherly love, they had five hundred years of democracy and peace—and what did that produce? The cuckoo clock

As an engineer I prefer the solution that uses the least amount of numbers.
