Answer:
Option(C)
Step-by-step explanation:
(i) A and B:
Work done by A and B in 1-day = (1/8).
(ii) B and C:
Work done by B and C in 1-day = (1/6).
(iii) C and A:
Work done by C and A in 1-day = (1/10).
Adding (i),(ii),(iii) we get
⇒ 2(A + B + C)'s 1 - day work = (1/8 + 1/6 + 1/10)
= 47/120.
(A + B + C)'s 1-day work = 47/240.
∴ A,B and C together can complete the work in 240/47 days (or) 5 (5/47) days.
Hope it helps!
