A logistics company transports goods using two types of vehicles: trucks ( ) and vans ( ). Each truck consumes 6 litres of fuel and requires 4 hours of driver time per trip. Each van consumes 3 litres of fuel and requires 5 hours of driver time per trip. The company must complete at least 120 litres worth of fuel usage and at least 200 driver hours per week. The cost per truck trip is Rs. 80 and per van trip is Rs. 50. Note: The company wants to fulfill these requirements at the lowest possible cost. Based on the above data, answer the given subquestions.
Which of the following correctly represents the objective function and constraints for the given problem

Consider the following constrained optimization problem:
Answer the sub-questions assuming that we take a very small step in the direction of interest.
At the point which of the following is/are feasible directions
A company produces two types of products P1 and P2. The cost price per unit of P1 and P2 are ₹2 and ₹3, respectively. The production process requires two types of resources: labor hours and machine hours. Each unit of p1 requires 2 labor hours and 1 machine hour, while each unit of P2 requires 1 labor hour and 3 machine hours. The company has constraints on the availability of labor and machine hours, which are 80 and 90 hours, respectively. Use the above information to answer the given sub-questions.
Choose the correct Primal optimization problem from the following.
A person went to the market to buy hens. Old hens can be bought for ₹ 200.00 each but young hens can be bought for ₹ 500.00 each. The old hens lay 3 eggs per week and the young hens lay 5 eggs per week. Each egg costs Rs. 11. A hen costs ₹ 50.00 per week to feed. If the financial constraint is ₹ 8000 per week to buy hens and the capacity constraint is that the total number of hens bought cannot exceed 20 per week. The objective is to earn more profit. Let x represent the number of old hens and y represent the number of young hens. Use the above information to answer the given subquestions
If (x*, y*) is the optimal solution of the primal, u1 and u2 are Lagrange multipliers then which of the following options is/are true?
A consumer wants to maximize his utility subject to some constraints. He consumes two goods g1 and g2 and the utility function is the sum of g1 and g2. His budget is Rs.100. The per unit price of goods g1 and g2 are Rs.3 and Rs.4 respectively. Chose the correct optimization problem.
A consumer wants to maximize his utility subject to some constraints. He consumes two goods x
and y and the utility function is the product of x and y. His budget is Rs.200. The per unit price of goods x and y are Rs.3 and Rs.4 respectively. Choose the correct optimization problem.
A company manufactures two types of products, A and B. Market research and available resources have indicated that the combined production level should not exceed 1200 products per week and demand for products of type B is at most half of that times production of products of type A. Further, the production level of products of type A can exceed three times the production of products of other type at most 600 units. If the company makes profits of $12 and $16 per products respectively on products A and B. If the number of products manufactured of type A and type B are x and y respectively, then formulate this problem so that the company can maximize the profit. Based on the above data answer the given subquestions
