**Basic Concepts :**

1) If A can do a work in ‘a’ days, then work done by him in 1 day is 1/a.

If B can do a work in ‘b’ days, then work done by him in 1 day is 1/b.

Then, in one day, if A and B work together, then work done by them in 1 day,

= (1/a + 1/b);

= (a+b)/ab.

In this case, **we take the total work to be done as 1. Hence, the work will be completed when 1 unit of work is completed.**

2) Suppose, A and B are working to build a wall while C is working to break the wall. In such case, the wall is being built by while it is broken by C. here, we consider that A and B are doing positive work in building the wall while C is doing a negative work as he is breaking the wall.

3) Work done per unit time is known as efficiency. It is also known as Work Rate.

**Efficiency = Work done/time **

4)** **The work equivalence is an application of the efficiency and formula,

**Work rate * time= work done**
