The ratio of the efficiencies of two workers, P and Q, is 5 : 2. If P can complete a project in 12 days, how
many days will Q take to complete the same project alone?
Answer: B. 30 days — Efficiency and time are inversely proportional. Since P:Q efficiency = 5:2 and P takes 12 days, Q takes 12 x 5/2 = 30 days.
- A.
24 days
- B.
30 days
- C.
35 days
- D.
40 days

Show answer & explanation
Correct answer: B
Efficiency and time are inversely proportional. Since P:Q efficiency = 5:2 and P takes 12 days, Q takes 12 x 5/2 = 30 days.
