There were 2 560 books altogether on 3 shelves. If the number of books on Shelf A was doubled, 180 books from Shelf B were removed and the number of
books on Shelf C was reduced by half, there would be an equal number of books on the 3 shelves. How many books were there on Shelf B?

WRONG!
The bot's answer does not fit the given information, besides, what is
the point of just blurting out some strange answer. This serves absolutely
no purpose and goes against everything this webpage used to stand for.
anyway ..... correct solution:
scenario #1:
A + B + C = 2560
scenario #2:
content of the shelves :
2A , B-180, C/2 <----- these are all equal
2A = C/2 or C = 4A
2A = B - 180 or B = 2A + 180
in A + B + C = 2560
A + (2A+180) + 4A = 2560
7A + 180 = 2560
7A = 2380
A = 340
then B = 2(340) + 180 = 860
and C = 4(340) = 1360
old: A = 340 , B = 860, C = 1360 , that adds up to 2560
new: A = 680 , B = 860-180 = 680 , C = 1360/2 = 680
my answer is right and the bot is wrong

Perhaps we are all helping with an early stage of bot development?
