A takes twice as much time as B and thrice as much time as C to finalise a task. Working together, they can complete the task in 8 days. The time (in days) taken by A, B and C, respectively, to complete the task is:
A. 42, 21, 14
B. 60, 30, 20
C. 54, 27, 18
D. 48, 24, 16
Answer: Option D
Solution (By Examveda Team)
Efficiency of A : B : C = 1 : 2 : 3Total work = 8 × (A + B + C) = 48
Time taken by A → $$\frac{{48}}{1}$$ = 48 days
Time taken by B → $$\frac{{48}}{2}$$ = 24 days
Time taken by C → $$\frac{{48}}{3}$$ = 16 days
