Question

The number of female 'good' students is

• A. 40
• B. 66
• C. 8
• D. 54

Answer 1

The correct option is C 8

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.

From the above table, it is clear that number of female good students =8
