Time and Work questions with solutions
Rahul can complete a piece of work in 6 days and Suresh can complete the same work in 12 days. In how many days will they finish it working together?
- (A)3 days
- (B)4 days
- (C)9 days
- (D)6 days
Show answer and explanation
Correct answer: (B) 4 days
Rahul's one-day work = 1/6 and Suresh's one-day work = 1/12. Together they do 1/6 + 1/12 = 18/72 = 1/4 of the work per day, so the work is finished in 4 days.
Shortcut: Days together = (a × b)/(a + b) = 72/18 = 4.
Neha can complete a piece of work in 30 days and Divya can complete the same work in 60 days. In how many days will they finish it working together?
- (A)19 days
- (B)22 days
- (C)20 days
- (D)45 days
Show answer and explanation
Correct answer: (C) 20 days
Neha's one-day work = 1/30 and Divya's one-day work = 1/60. Together they do 1/30 + 1/60 = 90/1800 = 1/20 of the work per day, so the work is finished in 20 days.
Shortcut: Days together = (a × b)/(a + b) = 1800/90 = 20.
