A alone worked for 6 days and then b joined him. After 10 more days a left and b took 2 more days to complete the work. If a and b together can do the work in how many days would each of them take to do the work individually

Answer 1

total work days = 6 + 10 + 2 = 18 days.
total people = 2
so to complete work each person will take = 18/2= 9
9 days each one will take.
