What to Focus On

  • If A does work in 'a' days, then A's one day work = 1/a
  • Combined work rate = Sum of individual work rates
  • Work Rate × Time = Work Done is the fundamental equation

  • Fractional Method: Total work = 1 unit, individual work = fractions
  • Percentage Method: Total work = 100%, individual work = percentages
  • LCM Method: Total work = LCM of time periods, eliminates complex fractions

  • Together: Combined rate = Sum of individual rates
  • Alternately: Calculate work done in 2-day cycles
  • Find complete cycles first, then remaining work

Common Mistakes to Avoid

If A can do work in 10 days and B in 15 days, then together they will take (10+15)/2 = 12.5 days

In alternating work problems, if A and B work alternate days, the total time is just the sum divided by 2

Efficiency ratios directly translate to time ratios in the same direction
