Answer: they'll finish their work in 14.58 days
Step-by-step explanation:
According to question,
1 man in 1 day can do 1/(20×20) = 1/400 work
1 woman in 1 day can do 1/(20×35) = 1/700 work
In 1 day, 16 man and 20 woman together can do = 16/400+20/700 = 12/175 work
Then together they'll finish their work on 1/(12/175) = 14.58 days
