Step-by-step explanation:

Here we know that 12 men=15 women from first statement

So 4 men=5 women

Now, as 15 women can do the work in 20 days, 1 woman can do the work in 15*20=300 days

Now we are asked how much time will 4 men and 5 women take to complete the work

Here we can take 4 men = 5 women and can find the time taken by 5+5=10 women to complete the work

We know that 1 woman can complete the work in 300 days, so 10 women will complete the work in 300/10=30 days

So the answer is 30 days

Answer:

4-5 =1/60 days

Step-by-step explanation:

THE ANS IS 30 days = 12 men do the work in 20 days. So one man alone does the work in 12 x 20 = 240 days.The fraction of work 4 men do per day = 4/240 = 1/60

15 women do the work in 20 days. So one woman alone does the work in 15x20 = 300 days

So the fraction of work a woman does a day = 1/300

The fraction of work 5 women do per day = 5/300 = 1/60

fraction of work 4 men + 5 women do per day = 1/60 + 1/60 = 1/30

Thus it would take 1/60 =30 days to complete the job.
