Yeah I actually went over to bato to see what they were saying. Someone had a reasonable explanation haha The question itself was "wrong" in the sense that it missed key information, but i don't exactly remember
Lmaooo I also came to that conclusion after staring at the question for 30 min and even asked an ai to solve it. It is most likely mistranslated and is missing con critical info.
The only reason I came to the comments is to ask what's with the freaky maths in CHP 12 ??? Shouldn't it have been 34???
