Running at same constant rate, 6 identical machines can provide a total of 270 bottles per minute. At this rate how many bottles could 10 such machines produce in 4 minutes?

A 648

B 10800

C 2700

D 1800

Correct Answer: Option D

6 identical machines can produce a total of 270 bottles per minute

-> Hence 1 machine can produce 270/6 bottles per min

so, 10 such machines produce in 4 minutes

-> 10 * 4 * 270/6 = 1800
