        A’s 1 day work = 1/x.

 

3.     If A’s 1-day work = 1/x, then A can finish a piece of work in x days.

 

4.     If A is X times as good a workman as B then:

Ratio of work done by A and B = X : 1

Ratio of time taken by A and B to finish a work = 1 : X.

 

5.If A can do a piece of work in x days and B can do it in y days then A and B working together will do the same work in xy/(x+y) days.
