Question

sita can do a piece of work in 3days Rita can do it alone in 6days and Gita in 9days if all three work together in how many days can they complete the work
​

Answer 1

Answer:

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
