Answers
Answer:
Number of days taken by A to complete work = 10
Work done by A in a day = 1/10
Number of days taken by A to complete work = 20
Work done by A in a day = 1/20
Work done by both A and B in a day = 1/10 + 1/20
= (1 X 2)/(10 X 2) + 1/20
= 2/20 + 1/20
= 3/20
Number of days both complete the work = Total work / Work done in a day
= 1 / 3 / 20
= 1 X 20/3
= 20/3 days
Hence your answer is 20/3 days.
