It is given that

Mean monthly salary of 20 workers = ₹ 45900

So the total monthly salary = ₹ (20 × 49500) = ₹ 918000

Mean monthly salary of 20 workers and manager = ₹ 49200

So the total monthly salary = ₹ (21 × 49200) = ₹ 1033200

We know that

Manager’s monthly salary = Total monthly salary of 20 workers and manager – Total monthly salary of 20 workers

By substituting the values

Manager’s monthly salary = 1033200 – 918000 = ₹ 115200

Therefore, the manager’s monthly salary is ₹ 115200.
