Time and work is a basic concept in quantitative aptitude that is often tested in government exams. It is the basis of how work gets done at a particular time. 

Here are some formulas for time and work:
Work Done = Time Taken × Rate of Work
Rate of Work = 1 / Time Taken
Time Taken = 1 / Rate of Work
Total Work Done = Number of Days × Efficiency
W = NXD
W = M × D 

Here are some tips for time and work problems:
Ratios of wages of individuals doing work are directly proportional to the ratio of the efficiency of the same individuals.
If X is three times better than Y, then in any given amount of time, X will complete 3 times more work than Y.
Time and work are related to indirect proportion.
If W can complete 1n of work in 1 day, then W will take n days to complete the whole work.
