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 14 such machines produce in 4 minutes ? Choose the correct choice from the following answers:
A) 2520  B) 1800  C) 2700  D) 10800  E) None of these
Solution   Let the required number of bottles be x.   More machines,More bottles (Direct Proportion)   More minutes,More bottles (Direct Proportion)   âˆ´ 6 Ã— 1 Ã— x = 14 Ã— 4 Ã— 270 â‡” x = 14x4x270/6= 2520 . 2520nswer 2520
