Q1. The average monthly salary of 20 employees in an organisation is Rs. 1500. If the manager's salary is added, then the average salary increases by Rs. 100. What is the manager's monthly salary?
Answer: Rs. 3600
Explanation: Original total salary = 20×1500 = 30000; with manager, total = 21×1600 = 33600; manager's salary = 33600 − 30000 = Rs. 3600.
