If the ratio of taxpayers to other persons in the same age group below 30 years is 1:2, then what is the number of taxpayers (in lakhs) in that age group?
Consider the following data:<br>The table below gives the age-wise population percentage of a city:<br><table> <thead> <tr> <th>Age group</th> <th>Percentage</th> </tr> </thead> <tbody> <tr> <td>Below 30 years</td> <td>14.00</td> </tr> <tr> <td>30-34.99</td> <td>29.75</td> </tr> <tr> <td>35-39.99</td> <td>26.25</td> </tr> <tr> <td>40-44.99</td> <td>0</td> </tr> <tr> <td>45-49.99</td> <td>18.50</td> </tr> <tr> <td>50 years and above</td> <td>11.50</td> </tr> </tbody> </table><br>The number of persons below the age of 40 years is 10.5 lakhs.
- A. 0.4
- B. 0.7 ✓
- C. 0.85
- D. 1.05
Correct Answer: B. 0.7
Explanation
Population below 30 years is 14\% of 15 lakhs = 2.1 lakhs. The ratio of taxpayers to others is 1:2, so taxpayers form \frac{1}{3} of this group. Taxpayers = 2.1 \times \frac{1}{3} = 0.7 lakhs.
