Answer:
They all can do the work in 2 days
Step-by-step explanation:
Work done by Sita in 1 day = 1/3 of the total work
Work done by Rita in 1 day = 1/6 of the total work
Work done by Gita in 1 day = 1/9 of the total work
If they work together, the work done by them in one day would get combined.
Work done by all of them in 1 day = 1/3 + 1/6 + 1/9
= 6 + 3 + 2/18
= 11/18
Work done by all of them in 2nd day = 2 x 11/18 = 22/18
22/18 is greater than total work, which is 1.
Therefore, they all can do the work in 2 days
