Consider the following for the next two (02) items that follow: The age distribution of a city population is: Below 30 years: 14.00%, 30-34.99 years: 29.75%, 35-39.99 years: 26.25%, 40-44.99 years: 0%, 45-49.99 years: 18.50%, 50 years and above: 11.50%. The number of persons below 40 years is 10.5 lakh. If the ratio of taxpayers to other persons in the age group below 30 years is 1 : 2, then what is the number of taxpayers (in lakhs) in that age group?
