Ganesh, Ram and Sohan together can do a work in 16 days. If Ganesh and Ram together can do the same work in 24 days then, how long will take Sohan alone to do the same work?

42 days
24 days
36 days
48 days

Correct Answer: 48 days

Explanation:

∵ Work of (Ganesh, Ram and Sohan) for 1 day = 1/16
and work of Ganesh and Ram for 1 day = 1/24
⇒ Work of Sohan for 1 day = 1/16 - 1/24 = 1/48
∴ Sohan alone will complete the work in = 1/(1/48) days = 48 days.
