In 2007, the respective ratio of number of appeared candidates to the qualified candidates was 5 : 4. Number of female qualified candidates constitutes what percent of number of appeared candidates in the same year ?

Solution

In 2007, let the number of appeared candidates = 500x

Let the no. of qualified candidates = 400x

Ratio of male qualified to female qualified = 5:3

=> No. of female qualified candidates in 2007 = $$\frac{3}{8}$$ * 400x = 150x

Required % = $$\frac{150x}{500x}$$ * 100 = 30%
