Rules on work and Time.

If M1 number of individuals are able to complete W1 amount of work within D1 days whereas M2 number of people are able to complete W2 amount of work in D2 days, then the formula used will be: M1*D1/W1 = M2*D2/W2

If the individuals are having productivity of E1 and E2 individually, then the formula used to calculate the same will be: M1*D1*T1*E1/W1= M2*D2*T2*E2/W2

If person A is able to do a part of work in ‘n’ number of days, then the work done by A in a single day is equals to 1/n

If person A might complete an amount of work in D1 number of days as well as person B is able to complete the similar amount of work in D2 number of days then person A and person B together can do the similar type of work in: (D1*D2)/ (D1+D2)

Considering that person A is double as worthy a worker as person B, then person A would be taking half of the time occupied by person B to do a similar amount of work.

If person A along with person B can collaboratively complete a part of work in D1 number of days as well as person A unaccompanied is able to complete it in D2 number of days, then person B can alone complete the work in: (D1*D2)/ (D2-D1)
