Question

In a constituency, 60% of the voters are males and the rest are females. 40% of the males are illiterates and 25% of females are literate. By what percentage is the number of literate males more than that of illiterate females? 

Options

• 22.5%

• 17.5%

• 25%

• 20%

Answer 1

20%

Explanation:

Let total 100x

60% voters are male = 100x × 60% = 60x

40% voters are female = 100x × 40% = 40x

Literate males = 36x

Illiterate females = 30x

Required percentage = `(6"x")/(30"x") xx 100`

= 20%
