Sita working 8 hours a day does the job in 6 days
So working 4 hours a day will take 12 days
So Sita in 1 day does 1/12 of the work in 4 hours
Similarly in 1 day Gita does 1/9 of the work in 4 hours
So together in 1 day they do 1/12+1/9 = 21/108 = 7/36 of the work
So they will finish the job in 36/7 days OR 5.14 days ANSWER
Verified answer
Answer:
Step-by-step explanation:
Work done by Gita in 6 days=1/3
1 day work of Gita= 1/3*1/6= 1/18
Work done by Sita in 3 days= 1/2
1 day work of Sita= 1/2*1/3= 1/6
One day work of Gita and Sita=
1/18+1/6=
1/18+3/18
=4/18
1/4.5
Gita and Sita take 4.5 days to complete the work
