A, B, C can do the work in half time as compared to C
It means :
A, B, C one day work is 2wice of C’s one day work
It means A, B one day work is equal to C’s one day work. - - - - (1)
Let A, B, C do it in t hours
A takes t+6 hrs and B takes t+1 hrs and C takes 2t hrs.
As per inference (1)
1/t+6 + 1/t+1=1/2t
Solving this gives t=2/3 hrs
C takes 2t =4/3 hrs = time taken by A, B together (inference from eq 1)
