# How to Solve the "PQR Product Mix" Problem Using Python and Gurobi

## How can we solve the "PQR Product Mix" problem using Python and Gurobi?

What are the steps and code needed to find the optimal solution for this problem?

## Solution:

To solve the "PQR Product Mix" problem using Python and Gurobi, follow these steps:

- Install the Gurobi Optimization Library and import the necessary modules.
- Formulate the linear programming (LP) problem by defining variables, objective function, and constraints.
- Optimize the model and print the optimal solution.

The "PQR Product Mix" problem involves maximizing the profit by determining the optimal mix of three products (P, Q, and R) based on their production costs and constraints on available resources.

In the provided Python code snippet, variables x1, x2, and x3 represent the quantities of products P, Q, and R respectively.

The objective function aims to maximize the profit, considering the cost coefficients of each product and their respective quantities.

Constraints are set based on the resource limits for each product, ensuring that the total production does not exceed the available resources.

By formulating the LP problem and using the Gurobi optimization library, you can efficiently find the optimal solution to maximize profit.

Make sure to install Gurobi and its necessary modules to run the Python code successfully and obtain the optimal objective value and variable values.
