Maths : Time and Work

Maths :: Time and Work


Direct variation and Indirect variation

Examples of Direct variation:
1. Interest and principal
    More principal earns more interest
2. Salary (wages) and workers
    More workers means more salary
3. Articles and cost
    Purchase of more articles costs more money
4. Distance and time
    More distance to travel, more time to spend

Examples of Indirect variation
1. Work and time
     More number of workers, the lesser will be the time
                              i.e., less number of days
2. Speed and time
   (i) Higher the speed, the lower is the time required to
       cover a distance
  (ii) A more capable person takes lesser time to 
       complete a job
3. Number and share
    More persons means, less will be the share of
    each person
