The objective function of an LPP is

• A) a constraint
• B) a function to be optimised
• C) a relation between the variables
• D) none of these

The objective function in a Linear Programming Problem (LPP) is a crucial component that defines what you are trying to achieve. It is specifically designed to be optimized, meaning you either want to maximize or minimize it based on the problem's requirements.

Understanding the Options

• A) A constraint: This is incorrect, as constraints limit the feasible solutions but do not represent the goal.
• B) A function to be optimised: This is the correct answer, as the objective function is what you aim to improve.
• C) A relation between the variables: While it does relate variables, its primary purpose is optimization.
• D) None of these: This option does not apply since option B is accurate.

Final Answer

The correct choice is B) a function to be optimised.
