What is the type of objective function it the given problem?

An animal feed company must produce 200 kg of a mixture consisting of ingredients A and B daily. A costs Rs. 3 per kg and B costs Rs. 8 per kg. Not more than 80 kg of A can be used and at least 60 kg of B must be used.

The primal problem refers to the original optimization problem, while the _______ problem is derived from the primal problem. The _______ provides insights into the bounds on the objective function and helps in interpreting the economic meaning of constraints.

_____________ is used for optimization problems where some or all of the decision variables must take integer values, often applied in scenarios like scheduling, facility location, and resource allocation.

The _____________ is the longest sequence of dependent tasks in a project, determining the minimum time required to complete the project.

____________ is the established time required to perform a task or operation under normal working conditions, allowing for allowances for rest, delays, and interruptions. It is used to set benchmarks for productivity.

are a set of basic hand motions used to analyze work processes. Developed by Frank and Lillian Gilbreth, they help in breaking down tasks into fundamental movements to identify inefficiencies and suggest improvements.

____________ are methods used to determine the time required to perform a task based on the time needed for predefined basic motions. These systems provide standard time values for common motions used in industrial tasks, helping to improve accuracy and consistency in time measurement

The worker took 5 minutes to complete the task during the study. The worker’s performance is rated at 95% compared to the standard worker. This means the worker is working slower than the standard. Allowances for personal needs, rest, and delays are 20%. Compute for the standard time in minutes.

The last four weekly values of sales were 90, 101, 105, and 95 units. The last four forecasts (for the same four weeks) were 70, 80, 95, and 90 units. Calculate MAD.

A department works on 8 hours shift, 250 days a year and has the usage data of a machine, as given below. Determine the number of machines required
