What is the average income from school as a salary per year earned by the person over the given years?

Accepted Answer

To find the average income from school salary over the given years, sum the school salary for all years and divide by the number of years.

School salaries per year (in thousand rupees): 132, 148, 166, 178, 196

Sum = 132 + 148 + 166 + 178 + 196 = 820 (thousand rupees)  
Number of years = 5

Average = 820 / 5 = 164 (thousand rupees)

Converting to rupees: 164,000

Hence, the average income from school salary per year is ₹1,64,000.
