Question

12 men and 15 women can do a work in 20 days then 4 men and 5 women can do it in how many days?​

Answer 1

Answer:

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 2

Answer:

Step-by-step explanation:

12 men can finish this work in 20 days. so 4 men can finish it in 60 days. so 4 men's one day's work = 1/60. 15 women can complete the same work in 20 days
