There are many situations in our daily lives where we must see how one quantity changes in response to other.

According to proportional rules, the quantity changes the amount concerning each other.

Example:
(i) The total cost will increase if the number of items purchased increases.
 
(ii) The more money is deposited in a bank, the more interest is earned.
 
(iii) As the speed of the vehicle increases, the amount of time taken to cover the same distance decreases.
 
(iv) For a given job, the greater the number of workers, the less time it will take to complete the work.
