Any two quantities are said to be indirectly proportional, if on the increase of one quantity, the other quantity decreases and vice-versa.

  • Example: If speed of car is increases, then the time required to cover the distance decreases.
    Speed of car (↑) Time required decreases (↓)
  • Example: Time taken to finish work increases, if number of men decrease.
    Time (↑) Number of men (↓)
