Given Information:
- A can finish the work in 20 days
- B can finish the work in 60 days
- A started the work alone and after 10 days, B joined him

Calculating the Work Efficiency of A and B:
- Work efficiency of A = 1/20 per day
- Work efficiency of B = 1/60 per day

Work Done by A in 10 days:
- In 10 days, A completes 10 * (1/20) = 1/2 of the work

Work Remaining:
- After 10 days, 1 - 1/2 = 1/2 of the work is remaining

Work Efficiency when A and B work together:
- Combined work efficiency of A and B = 1/20 + 1/60 = 4/60 + 1/60 = 5/60 per day

Time taken to complete the remaining work:
- Time = Work remaining / Combined work efficiency
- Time = (1/2) / (5/60) = (1/2) * (60/5) = 6 days
Therefore, A and B will take 6 days to complete the remaining work when they work together.
