Indian Economy - Understanding the basics of Indian economic system

The average income of 30 persons is Rs. 5,600 and that of another 25 persons is Rs. 5,000. Find the average income of the whole group.

Rs.4,578.25

Rs.4,589.26

Rs.5,238.29

Rs.5,327.27

- To find the average income of the whole group, combine the incomes of the two groups and then divide by the total number of people.

- The first group of 30 persons has an average income of Rs. 5,600, so their total income is 30 * 5,600 = Rs. 168,000.

- The second group of 25 persons has an average income of Rs. 5,000, so their total income is 25 * 5,000 = Rs. 125,000.

- Combine both totals: Rs. 168,000 + Rs. 125,000 = Rs. 293,000.

- The total number of persons is 30 + 25 = 55.

- Calculate the average income: Rs. 293,000 / 55 = Rs. 5,327.27.

Option:4, Rs.5,327.27 is the correct answer.
