What is Time and Work?
Time and work are concerned with the time taken by a person or a group of persons to complete a task and the efficiency of the work done by each of them. Time and work problems are important because there is a certain relationship between the number of persons doing the work, number of days or time taken by them to complete the work and the amount of work that is done.
Work done = Number of persons x Number of days
W = M x D
Time: Time is the duration during which any activity or work happens or continues.
Work: Work is a task or set of activities to achieve a certain result.
Here the unit of work is man days or man hours. The problems of time and work can primarily be divided into two types. This type includes problems where individuals work with different efficiencies either alone or in combination to complete a task. The second type includes problems where group efficiencies are involved.
The important terms related to time and work are given below:
Time Taken: Rate of work and time are inversely proportional to each other. Thus, R = 1/T
Work Done: It takes (T) time to complete a certain amount of work (W). The number of units of work done per unit time. Thus, Work Done (W) = Time (T) * Rate of Work (R)
Negative Work: Assume that there are two people A and B who have been assigned to build a table. Here, work refers to the building of a table. Also, assume that there is another person C who is assigned the task of damaging the table. Now, work done by C is termed as negative work as C is effectively lowering the amount of work done by A and B.
Work Equivalence: Please note that the work one by people/pipes can be stated mathematically as,
Work done = rate of work x time
Consider the following formula also,
M1D1T1 = M2D2T2 (provided work remains the same)
In the above formula,
M = Number of persons
D = Number of days
T = Number of hours.
The equation is called the “work equivalence formula”
Concept of Efficiency: Very often, you will get to read and solve time-work problems where it is usually mentioned that the efficiency of A is twice the efficiency of B or that A is three times more efficient than B. In the first case, it means that A takes one-half of the time taken by B to do the same amount of work. In the second case, it means that A’s efficiency is thrice that of B and so A will take one-third of the time taken by B to do the same amount of work.
Important Time and Work Formula
Given below are a few such important time and work formulas for your reference:
- Work Done = Time Taken × Rate of Work
- Rate of Work = 1 / Time Taken
- Time Taken = 1 / Rate of Work
- If a piece of work is done in x number of days, then the work done in one day = 1/x
- Total Wok Done = Number of Days × Efficiency
- Efficiency and Time are inversely proportional to each other
- X:y is the ratio of the number of men which are required to complete a piece of work, then the ratio of the time taken by them to complete the work will be y:x
- If x number of people can do W1 work, in D1 days, working T1 hours each day and the number of people can do W2 work, in D2 days, working T2 hours each day, then the relation between them will be
Time and Work Shortcut – Fraction Conversion?
| Number of days required to complete the work | Work that can be done per day | Efficiency in Percent |
| n | 1/n | (100/n)% |
| 1 | 1/1 | 100% |
| 2 | 1/2 | 50% |
| 3 | 1/3 | 33.33% |
| 4 | 1/4 | 25% |
| 5 | 1/5 | 20% |
| 6 | 1/6 | 16.66% |
| 7 | 1/7 | 14.28% |
| 8 | 1/8 | 12.5% |
| 9 | 1/9 | 11.11% |
| 10 | 1/10 | 10% |
| 11 | 1/11 | 9.09% |
