Time and WorkModerateSSC CHSL 2024
Anita can complete a piece of work in 10 days and Pooja can complete the same work in 40 days. In how many days will they finish it working together?
- (A)30 days
- (B)7 days
- (C)25 days
- (D)8 days
Correct answer: (D) 8 days
Anita's one-day work = 1/10 and Pooja's one-day work = 1/40. Together they do 1/10 + 1/40 = 50/400 = 1/8 of the work per day, so the work is finished in 8 days.
Shortcut: Days together = (a × b)/(a + b) = 400/50 = 8.
