Correct Answer: A
Solution :
(A + B)'s 1 day's work \[=\frac{1}{18}\] (B + Q's 1 day's work \[=\frac{1}{24}\] (A + C)' s 1 day's work \[=\frac{1}{36}\] On adding all three, 2 (A + B + C)'s 1 day's works \[=\frac{1}{18}+\frac{1}{24}+\frac{1}{36}\] \[=\frac{4+3+2}{72}=\frac{1}{8}\] \[\therefore \] (A + B + C)Y 1 day's work \[=\frac{1}{16}\] \[\therefore \] A, B and C together will complete the work in 16 days.You need to login to perform this action.
