50 minutes
Step-by-step explanation:
The time required by the worker 1 was 2minutes
The time required by the worker 2 was 3 minutes
therefore, time in total is 5 minutes...
therefore, total packets packed in 5 minutes by both workers together is 30
therefore,
30:5::300:x
where x is the time required to pack 300 packets...
therefore, 6:1::300:x
therefore, the product of means = the product of extremes
therefore, 6x=300
therefore, x=50
therefore, in 50 minutes both workers will be packing 300 packets...
