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?
Answer: Option
Explanation:
Let the required number of bottles be x.
More machines, More bottles (Direct Proportion)
More minutes, More bottles (Direct Proportion)
| Machines | 6 | : | 10 |  |
:: 270 : x |
| Time (in minutes) | 1 | : | 4 |
6 x 1 x x = 10 x 4 x 270
 x = |
(10 x 4 x 270) |
| (6) |
x = 1800.

It can also be more machines, Less Minutes (Indirect Proportion).
And Less Machine more minutes (Indirect Proportion). Right? Correct me If I am wrong.

Please anybody explain me how evaluate proportions?

6 machines gives 270 bottles in 1 minute.
Therefore 1 machine in 1 minute = 270/6 = 90/2 = 45.
Now 10 machines in 4 minutes = 45 * 10 * 2 = 1800.
Therefore 1 machine in 1 minute = 270/6 = 90/2 = 45.
Now 10 machines in 4 minutes = 45 * 10 * 2 = 1800.

Total bottles 270 for 6 machines in 1 minute...
for each machine...=270/6=45bottles...in 1mnt
for 10 bottles......45*10=450*4=1800..in 4mnts
for each machine...=270/6=45bottles...in 1mnt
for 10 bottles......45*10=450*4=1800..in 4mnts

Hi all,
It's a technique to solve these type of questions, gre technique.
6 10 16.
45 45 45.
270 450 total.
450 in a min so in 4min 1800.

6 machines = 270 (1min).
10 machines = ? (4min).
10 machines x 4 min = 40 machines (1 min).
Now cross multiply,
40x270/6 = 1800.
10 machines = ? (4min).
10 machines x 4 min = 40 machines (1 min).
Now cross multiply,
40x270/6 = 1800.

Production in 6 minutes = 270
Production in 01 minutes = 270/6
Production in 40 minutes = 270/6 *40 = 1800.
Production in 01 minutes = 270/6
Production in 40 minutes = 270/6 *40 = 1800.

Simple:
When Indirect proportion: M1*D1*H1 = M2*D2*H2.
When Direct Proportion: M1*D2*H1 = M2*D2*H2.
When Indirect proportion: M1*D1*H1 = M2*D2*H2.
When Direct Proportion: M1*D2*H1 = M2*D2*H2.

Simple way
6 - 270
10 - ?
= 450 bottles
Now 450 in 1 minute so in 4 minutes= 1800
6 - 270
10 - ?
= 450 bottles
Now 450 in 1 minute so in 4 minutes= 1800
