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?
Answer & explanation
Correct answer: option 1
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)
