SSC CGL Time and Work question with solution
Time and WorkModerate
Riya can complete a piece of work in 12 days and Neha can complete the same work in 24 days. In how many days will they finish it working together?
- (A)7 days
- (B)10 days
- (C)12 days
- (D)8 days
Correct answer: (D) 8 days
Riya's one-day work = 1/12 and Neha's one-day work = 1/24. Together they do 1/12 + 1/24 = 36/288 = 1/8 of the work per day, so the work is finished in 8 days.
Shortcut: Days together = (a × b)/(a + b) = 288/36 = 8.
