 Time and Work 

If A can do a piece of work in n days, then A’s 1 day’s work = 1/n

If A’s 1 day’s work = 1/n, then A can finish the work in n days.

Ratio:

If A is thrice as good a workman as B, then:
Ratio of work done by A and B = 3 : 1.
Ratio of times taken by A and B to finish a work = 1 : 3.

♦ If A can do a work in ‘x’ days and B can do the same work in ‘y’ days, then the number of days required to complete the work if A and B work together is

time_work_3

 

 

♦ If A can do a work in ‘x’ days and A + B can do the same work in ‘y’ days, then the number of days required to complete the work if B works alone is

time_work_4
