Question

The ratio of female 'good' students to male 'average' students is

• A. 2 : 1
• B. 2 : 3
• C. 3 : 5
• D. 1 : 6

Answer 1

The correct option is D 1 : 6

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.

Number of female good students =8
Number of males average students =48
Required ratio =8 : 48 =1 : 6
