Question

What fraction of total excellent students are female excellent students?

• A. 0.37
• B. 0.58
• C. 0.24
• D. 0.6

Answer 1

The correct option is B 0.58

From (II), 40% of total number of students =96
Total number of students $=\frac{96}{0.4}=240$
Number of boys =240-96 =144
From (I), number of average male students $=\frac{1}{3}\times 144=48$
From (III), number of excellent students $=\frac{1}{2}\times 240=120$
Number of excellent female =120-50=70
From these calculations, we get the following table.

Total number of excellent students =120
Number of female excellent students =70
Required fraction = $\frac{70}{120}=0.58$
