Answer 2

Answer:

Step-by-step explanation:

Let total of 240 units of work to be done.

Now as given A+ B can do 240/16= 15 units/day

Also B+C can do 240/15= 16 units/day

And given, C= 1.2 A., Substituting and solving the equations we get, A= 5 units/day, ie.e A will complete work in 240/5= 48 days
