# The average monthly salary of 15 workers in a factory is Rs.285 :

The average monthly salary of 15 workers in a factory is Rs.285. If the salary of the manager is included, the average becomes Rs.355. What is the manager’s salary?

- Rs.1,450
- Rs.1,430
- Rs.1,405
- Rs.1,400

**Answer: (3) Rs. 1, 405**

**Explanation:-**

The average monthly salary of 15 workers in a factory = Rs. 285

Then, the total monthly salary of 15 workers in a factory = 15 x 285

= Rs. 4275

If the manager is included, the average becomes Rs.355.

Then, the total salary of 15 workers and manager = 16 x 355

= Rs. 5680

Thus, the salary of manager = 5680 – 4275

= Rs. 1, 405

Hence, the correct answer is option (3) Rs. 1, 405.
