A can do a piece of work alone in 96 days and B can do it alone in 104 days. In how many days can the duo, working together, complete the work?
Answer & explanation
Correct answer: option 2
A = 96 days,
B = 104 days,
⇒ Time required for A + B to complete the work = \(\frac{1248}{13+12}\) = \(\frac{1248}{25}\) = 49.92 days, ..(\(\frac{Work}{Efficiency}\) = Time)
