A) 1/24 days

B) 7/24 days

C) 24/7 days

D) 24/11 days

Correct Answer:
C) 24/7 days

Description for Correct answer:

A’s one day work = 1/24

B’s one day work = 1/6

C’s one day work = 1/12

(A+B+C)’s one day work  = 1/24 + 1/6 + 1/12

= > \( \large\frac{1 + 4 + 2}{24} = \frac{7}{24}\)

They will complete the same work 24 / 7 days
