Script for Time And Work Rules

If A can do a piece of work in n days, then Time And Work Rules
The work done by A in one day = 1/n

If A is twice as good a workman as B, then A will take half of the time taken by B to complete a piece of work.

If A and B together can do a piece of work in x days, B and C together can do in y days and C and A together can do in z days, then the same work can be done.

This rule can be used in almost every problems.

If M₁ persons can do W₁ work in D₁ days and M₂ persons can do W₂ works in D₂days then we can say
M₁D₁W₂ = M₂D₂W₁

If the persons work T₁ and T₂ hours per day respectively then the equation gets modified to
M₁D₁T₁W₂ = M₂D₂T₂W₁

If the persons has efficiency of E₁ and E₂ respectively then,
M₁D₁T₁E₁W₂ = M₂D₂T₂E₂W₁
