Four workers are available to perform jobs 1–4. unfortunately, three workers can do only certain jobs: worker 1, only job 1; worker 2, only jobs 1 and 2; worker 3, only job 2; worker 4, any job. draw the network for the maximum-flow problem that can be used to determine whether all jobs can be assigned to a suitable worker.

The value of 300 is divided into 120 and 180 in the ratio of 2:3.

Step-by-step explanation:

Let us assume that the common factor be x in the ratio.

It is known that, 2x + 3x = 300

⇒ 5x = 300

⇒ x = 300/5

⇒ x =60.

To find the values of A and B :

A= 2x

⇒ 2(60)

⇒ 120

B= 3x

⇒ 3(60)

⇒ 180

The value of 300 is divided into 120 and 180 in the ratio of 2:3.
