Zee and Gee can complete a task together in 24 days. If the efficiencies of Zee and Gee are in the ratio 3 : 8, respectively, then in how many days can Gee complete the task alone?

33 days

Zee + Gee = 24 days,

Z : G = 3 : 8  (Efficiency)

⇒ Total work = (3 + 8) x 24 = 11 x 24 = 264 units,  ..(Efficiency × Days = Total work)

⇒ Time required by Gee to complete the work alone = \(\frac{264}{8}\) = 33 days,  ..(\(\frac{Work}{Efficiency}\) = Time)
