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
Answer: Option B

Let the required number of bottles be x.


More machines, More bottles (Direct Proportion)


More minutes, More bottles (Direct Proportion)


 


Machines
6
:
10
Running At The Same Constant Rate, 6 Identical Machines Can ...
:: 270 : x
Time (in minutes)
1
:
4

So,  6 x 1 x x = 10 x 4 x 270


x = \(\frac{(10\times4\times270)}{(6)}\) 


x= 1800.
