no, it says 6 idential machines can produce a total of 270 bottles in a minuet. check the below.
Just came home after a long night out and am a bit out of it so to speak -I could swear that I have seen this question in some book a while back and it said "270 bottles a minute each", hence the OA being 10800. Guess I should have read the first post more closely
I do not understand why the question stem would tell us anything about running at the same constant rate if it meant 6 machines produce 270 bottles though.
Could you please post the book and page you got the question from, as well as the OE.
