Okay, let’s calculate this. Praveen has 2+ years of experience as a design engineer, which is a relatively early stage in his career. Location is Chennai, India, which has a lower cost of living compared to the US or other Western countries. Mechanical engineers with similar experience in India can charge lower rates. Considering the industry average for mechanical engineers in India, I’d estimate around ₹50,000–₹100,000 (approximately $65–$130 USD) per month. Since Praveen is in the early stages of his career, I’ll adjust this downward to ₹30,000–₹60,000 (approximately $40–$80 USD) per month. To convert this to an hourly rate, let’s assume a 40-hour workweek and 4 weeks per month. This gives us approximately ₹1,000–₹2,000 (approximately $1.30–$2.60 USD) per hour.
