Each machine can produce (270/6) = 45 bottles per minute
45 * 10 = 450 bottles per minute
450 * 4 = 1800 bottles in 4 minutes.

Let's take the approach that uses the answer choices to eliminate wasted time.
270/6 is a little less than 300/60 = 50 bottles per minute per machine. 10 machines = 500 per minute. 4 minutes worth = 2000 bottles as being slightly HIGHER than the answer we need.
Looking at the answers it is clear...we can only choose (B) 1800 bottles starting with an upper bound of 2000.

Running at the same constant rate, 6 identical machines can prod [#permalink]

270/6 = 45 BPM X 10 Machines = 450 BPM X 4 MIN = 1,800.
Kudos if this is easier!
