Answer 2

Answer:

If Ashok and Amit work together, 12 days are required to complete the work.

Step-by-step explanation:

Ashok completes the work in number of days = 20

The work Ashok do in one day = 1/20 of the total work

Similarly, Amit finishes the same work in number of days = 30

The work Amit can do in one day = 1/30 of the total work

If they work together the work they will do in one day:-

$=\frac{1}{30} +\frac{1}{20}$

$=\frac{5}{60}=\frac{1}{12}$

Therefore, they will complete 1/12 of the total work together in one day.

Therefore, Ashok and Amit will take 12 days to complete the whole work.
