Directions (37-40): Read the given information carefully and answer the questions based on it: Four machines (J, K, L and M) are arranged in a production line to manufacture a specific product. Each machine has distinct operational rules and performs a different function in the manufacturing process. The factory works from 9:00 AM to 6:00 PM every day, and each product must pass through the machines in a specific order (J -> K -> L -> M) to be completed. Each machine has a fixed processing time per product, but machines cannot process more than one product at a time. Here is the information about the machines: Machine J: Takes 8 minutes to process a product. The products enter at 10-minute intervals starting at 9:00 AM. Machine K: Takes 10 minutes to process a product. It starts working only if Machine J has completed its task and sends the product forward. Machine L: Takes 12 minutes to process a product. It requires a 4-minute cooldown period before processing the next product. Machine M: Takes 9 minutes to process a product. It can only start processing a product if it receives it before or exactly on the half-hour mark (that is, the :00 or :30 mark of any hour). Otherwise, the product must wait until the next such mark. The factory stops accepting new products for processing at 12:00 Noon.
