B Correct answer
Explanation

Total population below 40 is 10.5 lakhs. Percentage below 30 is 14%, 30-34.99 is 29.75%, 35-39.99 is 26.25%. Total percentage < 40 = 14 + 29.75 + 26.25 = 70%. 70% = 10.5 lakhs, so 1% = 0.15 lakhs. Below 30 years = 14% = 14 * 0.15 = 2.1 lakhs. Taxpayers ratio 1:2 means 1/3 of 2.1 = 0.7 lakhs.

AI explanation

The total percentage of the population below 40 years is 14 + 29.75 + 26.25 = 70 percent. Since this equals 10.5 lakhs, the population below 30 years is 14 percent of this total, calculated as (14 / 70) * 10.5 = 2.1 lakhs. Given the ratio of taxpayers to other persons is 1:2, the number of taxpayers is 2.1 * (1 / 3) = 0.7 lakhs. The result is 0.7.
