Fundamental Concepts and Formulas for Work and Wages

• If a person can do a piece of work in ‘n’ days, then in one day, the person will do ‘1/n’ work. Conversely, if the person does ‘1/n’ work in one day, the person will require ‘n’ days to finish the work.
• In questions where there is a comparison of work and efficiency, we use the formula 
  M1 D1 H1 E1 / W1 = M2 D2 H2 E2 / W2, where 
  M = Number of workers 
  D = Number of days 
  H = Number of working hours in a day 
  E = Efficiency of workers 
  W = Units of work
•  In case we have more than one type of workers, then the formula modifies to 
  ∑(Mi Ei) D1 H1 / W1 = ∑(Mj Ej) D2 H2 / W2, where ‘i’ and ‘j’ may vary as per the number of workers.
• If a person A is ‘n’ times more efficient than person B, then 
  Ratio of work done by A and B in one day (Ratio of efficiencies) = n : 1 
  Ratio of time taken by A and B = 1 : n 
   

Total work = No. of Days x Efficiency

If a group of people are given a salary for a job they do together, their individual salaries are in the ratio of their individual efficiencies if they work for the same number of days. Otherwise, salaries are divided in the ratio of units of work done.

In this topic, the way of attempting the questions is the deciding factor for getting an accurate answer in less time. We shall try to cover all the types of questions asked in this topic with a detailed explanation of ways of attempting them.
