Question
The average salary per month of 30 employees in a company is Rs. 4000. If the manager’s salary is added, the average salary increases to Rs. 4300, what is the salary of the manager?
Solution 1
Step 1: Calculate the total salary of the 30 employees before the manager's salary is added.
The average salary of 30 employees is Rs. 4000. So, the total salary of 30 employees is 30 * 4000 = Rs. 120,000.
Step 2: Calculate the total salary of all the employees after the manager's salary is added.
The average salary of all the employees (including the manager) is Rs. 4300. Since there are now 31 employees (30 employees + 1 manager), the total salary of all the employees is 31 * 4300 = Rs. 133,300.
Step 3: Find the manager's salary.
The manager's salary is the difference between the total salary of all the employees after the manager's salary is added and the total salary of the 30 employees before the manager's salary is added.
So, the manager's salary is Rs. 133,300 - Rs. 120,000 = Rs. 13,300.
Solution 2
Sure, here is the step by step solution:
Step 1: Calculate the total salary of 30 employees before the manager's salary is added.
The average salary of 30 employees is Rs. 4000. So, the total salary of 30 employees is 30 * 4000 = Rs. 120000.
Step 2: Calculate the total salary of 31 employees (including the manager) after the manager's salary is added.
The average salary of 31 employees (including the manager) is Rs. 4300. So, the total salary of 31 employees is 31 * 4300 = Rs. 133300.
Step 3: Find the manager's salary.
The manager's salary is the difference between the total salary of 31 employees and the total salary of 30 employees. So, the manager's salary is 133300 - 120000 = Rs. 13300.
