Answer 2

Answer: Given A can do work in 14 days and B can do work in 21 days.

Step-by-step explanation:so the work done by A in 1 day = 1/14 and work done by B in day = 1/21. They worked together for 6 days so (1/14+1/21)×6=5/7.Then the left over work is 1-5/7=2/7.B can do work in 21days so the remaining work B can complete in how many days = 2/7×21=6.So B completed work in 6 days.
