Time & Work
If A can do a piece of work in x days, then A’s work in one day’s work = 1/x
If A’s single-day work is 1/x, then A can finish the work in x days.
If A does twice as much work as B, then A to B’s Ratio of work done in a given period is 2:1. Ratio of time taken by A:B is 1:2
Time taken is inversely proportional to work done.
Time & Work Important Formulae
Time & Work Questions are often difficult to understand, but with a few important formulae, you can easily understand and solve these questions.
Work Done by one person = (Total Work) / (Number of people)
Work Done in one day = (Total Work) / (Number of days)
Work Done by one person in one day = (Total Work) / (Number of people)(Number of days)
