In a constituency, 55% of the total number of voters are males and the rest are females. If 40% of the males are illiterate and 40% of the females are literate, then by what percentage is the number of illiterate females more than that of the illiterate males (correct to one decimal place)?
In a constituency, 55% of the total number of voters are males and the rest are females. If 40% of the males are illiterate and 40% of the females are literate, then by what percentage is the number of illiterate females more than that of the illiterate males (correct to one decimal place)? Correct Answer 22.7%
Given:
The number of voters are males = 55%
Number of males who are illiterate = 40%
Number of females who are literate = 40%
Calculation:
The number of voters are males = 55%
Number of voters who are females = (100 – 55)% = 45%
Number of males who are illiterate = (55 × 40/100)
⇒ 22
Number of males who are literate = (55 – 22) = 33
Now,
Number of females who are literate = (45 × 40/100)
⇒ 18
Number of females who are illiterate = (45 – 18) = 27
The percentage is the number of illiterate females more than that of the illiterate males =
⇒ (5/22 × 100)
⇒ 500/22
⇒ 22.7%
∴ The required percentage is 22.7%
