X, Y and Z, each working alone can complete a job in 6, 8 and 12 days respectively. If all three of them work together to complete a job and earn $2350, what will be Z's share of the earnings?	Select the correct option
A) $525  B) $550.50  C) $1080.02  D) $522.3  E) $1020.2
The dollars earned will be in the same ratio as amount of work done   1 day work of Z is 1/12 (or 2/24)   1 day work of the combined workforce is (1/6 + 1/8 + 1/12) = 9/24   Z's contribution is 2/9 of the combined effort   Translating effort to $ = 2/9 * 2350 = $522.3   hence:$522.3
