After 3.2 days, they will finish the work.
Step-by-step explanation:
Given that,
Sara's efficiency = 1/9
Areebas efficiency = 1/12
Neha's efficiency = 1/9
Work Done by all of them in 1 day = 1/9 + 1/12 + 1/9
= (4 + 4 + 3)/36
= 11/36
Time taken to complete the work;
1 = 11/36
= 3.2 days
Thus, they will complete the work together in 3.2 days.
