Quantitative Aptitude: Time and Work
Three main factors of Time and Work
There is a definite relationship between Time and Work. In this concept, there are only three factors
- Time is taken to complete a certain job
- Unit of work done
- Number of persons doing the job
There is a mental relationship between these three, discussed as follows:
Work done (W) = Number of days (Time taken) (T or D) × Number of men (M)
W = D × M
Some basic points
More number of men can do more work i.e. both are directly proportional
More number of men take less time to complete certain jobs i.e. both are inversely proportional
By summarizing, we get
w1/w2= m1/m2 x d1/ d2
Example 1: 10 men can cut 8 trees in 16 days. In how many days can 6 men cut 10 trees?Solution: This is a very simple example. You are given:
W1 = 8
W2 = 10
M1 = 10
M2 = 6
D1 = 16
D2 =?
By Using above formula you can get – D2 == 33.3 %
Concept of efficiency
This means, “How much work one person can do in one day (expressed in percentage)” For example A person can do a job in 2 days
