A) 367500
B) 551250
C) 594000
D) 376500
Correct Answer: B
Solution :
Total population of town |
\[=15\times \frac{\text{Number}\,\,\text{of}\,\,\text{males}}{\text{Number}\,\,\text{of}\,\,\text{females}}=\frac{7}{8}\] |
\[\therefore \]Number of males and females \[=7x\] and \[8x\] |
Number of male children \[=25%\]of \[7x\] |
\[=\frac{25}{100}\times 7x=1.75x\] |
Number of female children \[=20%\] of\[8x=\frac{20}{100\times 8x}=1.6x\] |
\[\therefore \] Number of adult female\[=8x-1.6x=6.4x\] |
\[\Rightarrow \] \[6.4x=235200\] |
\[\Rightarrow \] \[x=\frac{235200}{6.4}=36750\] |
\[\therefore \] Total population of town\[=15\times 36750=551250\] |
