To find the number of boys in the town, you can calculate 21% of the total population.
The total number of people in the town is 42.
Calculate the number of boys:
\[
\text{Number of boys} = \text{Total population} \times \left(\frac{\text{Percentage of boys}}{100}\right)
\]
\[
\text{Number of boys} = 42 \times \left(\frac{21}{100}\right)
\]
\[
\text{Number of boys} = 42 \times 0.21 = 8.82
\]
Since the number of boys must be a whole number, you would round this to the nearest whole number. Therefore, there are approximately 9 boys in the town.
