Linear Programming

A manufacturer produces two types of products A and B, which require 2 hours and 3 hours respectively for production on machine I, and 4 hours and 2 hours respectively on machine II. The machine I has 20 hours and machine II has 18 hours available per week. The profit on each product of type A is ₹6 and on type B is ₹8. Formulate the problem as a linear programming problem to maximize the profit.
