Answer 2

Answer:

Step-by-step explanation:

Concept:

            Indirect proportion is related to time and work.In both directions, when one quantity rises, the other falls, and vice versa.It takes less time to finish the same amount of work when people work more hours.On the other hand, it will take longer to finish a task if there are fewer men working on it.

Given:

            Atul can plough a field in 10 days while Raju can plough it in 15 days

Find:

       How many days will they complete if they plough together

Solution:

Let Atul (A) can plug the field  in one day be 1/10

Let Raju(B)can plug the field  in one day be 1/15

Therefore

(A+B)’s one day's work = 1/10+1/15 = 3+2/30= 5/30

Therefore total days required for (A+B)=30/5=6

Therefore answer is 6 days
