Answer» Correct Answer - Option 2 : 3 days Given: Manisha can complete a job in 5 days. Formula Used: Total work = Efficiency × Time Calculation: According to the question: Manisha can do a piece of work in 5 days Akshata can do the same work in 10 days Nimisha can do the same work in 30 days. So together they can do the piece of work in 1 day ⇒ (1 / 5 + 1 / 10 + 1 / 30) ⇒ (12 + 6 + 2) / 60 ⇒ 20 / 60 ⇒ 1 / 3 ∴ If all of them work together the work will be completed in 3 days. |
