SSC CGL Time and Work question with solution
Time and WorkModerateSSC CGL 2024
Neha can complete a piece of work in 24 days and Riya can complete the same work in 40 days. In how many days will they finish it working together?
- (A)32 days
- (B)14 days
- (C)17 days
- (D)15 days
Correct answer: (D) 15 days
Neha's one-day work = 1/24 and Riya's one-day work = 1/40. Together they do 1/24 + 1/40 = 64/960 = 1/15 of the work per day, so the work is finished in 15 days.
Shortcut: Days together = (a × b)/(a + b) = 960/64 = 15.
