★ Answer ↴

The method in which the value of a unit quantity is first calculated to get the value of any quantity is called the unitary method. In unitary method we have two types of variations :

1. Direct variation:

Condition: Increase in one quantity causes increase in the other and decrease in one quantity causes decrease in the other .

Examples:

• With more money , more articles can be bought.
• With less number of men , less work can be done in same time .
• With a greater speed a larger distance can be covered in the same time.

2. Inverse variation:

Condition: Increase in one quantity causes decrease in the other and decrease in one quantity causes increase in the other.

Examples:

• With a greater speed, less time will be taken to cover the same distance .
• With less number of men , more days are required for the same work .

●The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
