B Correct answer
Explanation

Total income is 125 * 9500 = 1,187,500. Income of 65 people is 65 * 6500 = 422,500. Income of 50 people is 50 * 7000 = 350,000. The remaining 10 people (125 - 65 - 50) have a total income of 1,187,500 - 422,500 - 350,000 = 415,000. The average income of the rest is 415,000 / 10 = 41,500.

AI explanation

The total income for all 125 people is 125 multiplied by 9500, which equals 1,187,500. The total income for 65 people is 65 multiplied by 6500, equaling 422,500, and the total income for another 50 people is 50 multiplied by 7000, equaling 350,000. The remaining 10 people have a total income of 1,187,500 minus 422,500 minus 350,000, which is 415,000. Dividing this by 10 gives their average income, Rs. 41,500.
