Question

if 8 workers can do a job in 16 days , how many workers will it take to do the job in 32 days​

Answer 1

Answer: 19.2

Step-by-step explanation:8 men take 16 days so 4 (half of 8) take 16x2=32 days or 4 men do 1/32nd part /day of the job ,

16 women take 24 days , so 8 women (half of 16) will take 24x2= 48 days . Or 1/48th part/day .

So together they do 1/32+1/48= 5/96th part/day .

So they will take 96/5 =19.2 days to complete it
