Final answer:
The question about the number of employees involved in manufacturing at Mahindra & Mahindra cannot be answered with the provided data as it does not specifically pertain to the company's workforce. Accurate numbers would require access to Mahindra & Mahindra's internal workforce data or public corporate reports.
Step-by-step explanation:
To determine how many employees are involved in manufacturing at Mahindra & Mahindra from a total workforce of 30,000, we would require specific data from the company. However, the information provided does not relate directly to Mahindra & Mahindra's workforce composition. Instead, it discusses the distribution of preferences for trucks among different job roles in a general population sample, the production capabilities of workers in the United States and Mexico in hypothetical scenarios involving shoe and refrigerator manufacturing, and the trend of outsourcing manufacturing jobs to developing nations.
It is common for larger corporations to have a variety of job roles, and not all would be involved in the manufacturing process. Depending on the company's structure, manufacturing employees could range from manual laborers to non-manual workers engaged in the production line. To obtain an accurate count of manufacturing employees for Mahindra & Mahindra, one would typically look at the company's annual report, sustainability report, or any official documentation outlining their workforce statistics.
