How can least cost combination of inputs can be achieved.?

The least cost combination of inputs can be achieved by utilizing the principle of equimarginal returns, which involves equating the marginal product per dollar spent on each input. This requires analyzing the cost and productivity of each input and adjusting their quantities until the ratio of marginal product to price is the same across all inputs. Additionally, employing optimization techniques, such as linear programming, can help identify the most cost-effective mix of inputs while satisfying production constraints. Regularly assessing input prices and productivity can further enhance cost efficiency.
