The number of girls in school B in the year 2009 is approximately what percent of the total number of students in school E in the year 2006 ?

Answer: Option E

Number of girls in School B in 2009
= 5.9 × 100
= 590
Total Number of students in School E in 2006
= (5.5 + 3.6) × 100
= 9.1 × 100
= 910
$$\begin{array}{rl}& \text{Required }\%\\ & =\left(\frac{590}{910}\times 100\right)\%\\ & =\frac{5900}{91}\%\\ & =64.8\%\\ & \approx 65\%\end{array}$$
