Time and Work questions with solutions
Sneha can complete a piece of work in 10 days and Riya can complete the same work in 15 days. In how many days will they finish it working together?
- (A)8 days
- (B)5 days
- (C)12.5 days
- (D)6 days
Show answer and explanation
Correct answer: (D) 6 days
Sneha's one-day work = 1/10 and Riya's one-day work = 1/15. Together they do 1/10 + 1/15 = 25/150 = 1/6 of the work per day, so the work is finished in 6 days.
Shortcut: Days together = (a × b)/(a + b) = 150/25 = 6.
Divya can complete a piece of work in 15 days and Sneha can complete the same work in 60 days. In how many days will they finish it working together?
- (A)11 days
- (B)45 days
- (C)12 days
- (D)37.5 days
Show answer and explanation
Correct answer: (C) 12 days
Divya's one-day work = 1/15 and Sneha's one-day work = 1/60. Together they do 1/15 + 1/60 = 75/900 = 1/12 of the work per day, so the work is finished in 12 days.
Shortcut: Days together = (a × b)/(a + b) = 900/75 = 12.
