Question:

The degree of an objective function of a linear programming problem is

Show Hint

Tip 1: The word 'Linear' in Linear Programming itself specifies that the degree of the function and constraints must be 1.
Tip 2: If the degree were higher, it would fall under Non-Linear Programming.

The Correct Option is B

Solution and Explanation

Concept:

• Linear Programming (LP) is a method to achieve the best outcome in a mathematical model whose requirements are represented by linear relationships.
• A linear relationship or function is a polynomial of degree 1.

Step 1:
Define the objective function form
In any standard LPP, the objective function \( Z \) is typically written as: \[ Z = ax + by \]
where \( a \) and \( b \) are constants and \( x, y \) are decision variables.

Step 2:
Determine the degree of the expression
The degree of a term is the sum of the exponents of the variables in that term.
In \( ax \), the exponent of \( x \) is 1.
In \( by \), the exponent of \( y \) is 1.
Since the highest power of the variables is 1, the degree is 1.
