Question

the average salary of 20 person in an office is Rs.1900 if the salary of the manager is added it becomes 2000 what is the annual salary of the manager?​

Answer 1

Answer: Rs 000

Step-by-step explanation:

otal salary of 20 workers + manager = Rs.2000×21 = Rs.42000  

Total salary of 20 workers = Rs.1900×20 = Rs.38000  

Monthly salary of the manager = Rs.42000 - 38000 = Rs.4000

Answer 2

The annual salary of the manager is 4000

Step-by-step explanation:

$Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}$

The average salary of 20 person in an office is Rs.1900

So,$1900 =\frac{\text{Sum of salaries of 20 person}}{20}$

$1900 \times 20 = \text{Sum of salaries of 20 person}\\38000= \text{Sum of salaries of 20 person}$

Let the salary of manager be x

If the salary of the manager is added it becomes 2000

So, $2000= \frac{38000+x}{21}$

$2000 \times 21 = 38000+x$

42000-38000=x

4000=x

Hence the annual salary of the manager is 4000
