Answer is 24
X and Y and Z complete a work in = 6 days;
One day's work of (X+Y+Z) = 16;
X complete the work in = 16 days;
One day's work of X = 116;
Y complete the work in = 16 days;
One day's work of Y = 116;
Then, Z's one day's work = TotalWork - X's Work -Y's Work
=>16−116−116=>16−216
=>(16−12)96
=>496
=>124
Thus, Z can complete the work in = 24 days.
