X completes a work in 12 days, whereas Y completes the same work in 16 days. If P is 1\(\frac{1}{2}\) times as fast as X. In how many days can Y and P together complete the work?
Answer & explanation
Correct answer: option 2
Efficiency of P = 1\(\frac{1}{2}\) x 4 = 6
Time taken by Y and P together to complete the work = \(\frac{Total\; work}{Efficiency}\)
= \(\frac{48}{9}\) = 5\(\frac{1}{3}\) days
