The following table shows Net National Income (in Lac Crore) and Per capita Net National Income (in thousand) of India during the 5 year period from the year 2015-16 to 2019-20. Based on the data in the table, answer the questions that follow

Year	Net National Income (in Lac, Crore rupees)	Per Capita Net National Income (in thousand rupees)
2015-16	122	95
2016-17	136	105
2017-18	151	115
2018-19	167	126
2019-20	177	132

What is the average per capita Net National Income (in thousand rupees) per year?

The correct option is 114.6.

To find the average per capita Net National Income (in thousand rupees) per year, we need to calculate the arithmetic mean of the per capita Net National Income values for all five years shown in the table.

First, let us identify the per capita Net National Income values for each year from the third column of the table:
- 2015-16: 95 thousand rupees
- 2016-17: 105 thousand rupees
- 2017-18: 115 thousand rupees
- 2018-19: 126 thousand rupees
- 2019-20: 132 thousand rupees

Next, we sum these values to get the total per capita Net National Income over the 5-year period:

$$\text{Total}=95+105+115+126+132=573$$

Since the data spans a period of 5 years, we divide the total sum by 5 to find the average per year:

$$\text{Average}=\frac{573}{5}=114.6$$

Therefore, the average per capita Net National Income per year is 114.6 thousand rupees.
