Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. At this rate, how many bottles could 10 such machines produce in 4 minutes? Options:	A) 648	B) 1800	C) 2700	D) 10800	E) None
Let the number of required bottles be x   machine 6 : 10   Time 1: 4   = :: 270 : x   Therefore 6 x 1 x X = 10 x 4 x 270   =&gt; x= (10 x 4 x 270) /(6)   =&gt; x = 1800   Answer: Option 1800
