A and B can do a work in 6 days, B and C in 2 days and C and A in 8 days. In how many days will the work be completed, if all three of them work together? Choose the correct choice from the following answers:
A) 12/24
B) 48/63
C) 45/56
D) 48/19
E) 28/12
One day work of A and B = 1/6   One day work of B and C = 1/2   One day work of C and A = 1/8   2(A + B + C) = 1/6 + 1/2 + 1/8   2(A + B + C) = 19/24   (A + B + C) = 19/48   Number of days required = 48/19 days.   Answer: 48/19
