The average monthly income of six employees in an office is ₹24,000. When a new employee joins the office, the average income of all seven employees becomes ₹25,500. What is the monthly income of the new employee?
₹34,500
Total income of the six employees: \(6 \times 24000 = 144000\).
Total income of all seven employees: \(7 \times 25500 = 178500\).
Income of the new employee is the difference: \(178500 - 144000 = 34500\).
Hence, the monthly income of the new employee is ₹34,500.
