Step-by-step explanation:

(A+B)'s 3 days work

=(6+5)×3

=33

As 2 days work c join A,

A=6×2=12

Now remainin work = 60−(33+12) = 15

Now , the work is complted in 2 days

So,per day efficiency is

=152=7.5

Let c's per day efflciency is (c)

so A and C combine per day efficiency is=A+C=6+C

So,6+C=7.5

C = 1.5

So,work complted by c in=601.5=40 days
