Practicing Success
Aarush and Maahi together can do a piece of work in 10 days. If Aarush alone can do the same work in 15 days, then how many days Maahi alone will take to do the same work? |
25 15 30 20 |
30 |
Aarush + Maahi = 10 days, Aarush = 15 days, ⇒ Simplifying from the above diagram, we get efficiency of Maahi =1 ⇒ Time required for Maahi to complete total work = \(\frac{30}{1}\) = 30 days |
