Solution
Given
In this question, we are given that
- • In a country 55.55 % of the population are males and rest females
• Of the males 60 % are literate and of the females 40 % are literate
To find
We need to determine
- • The percentage of the population that are literate
Approach and Working out
Let us assume that total population of the country is 90.
- • Hence, male population = 55.55% of 90 = 50
• And, female population = 90 – 50 = 40
Also, 60% of the males and 40% of the females are literate
- • Hence, literate male = 60% of 50 = 30
• And, literate female = 40% of 40 = 16
• Therefore, total literate population = 30 + 16 = 46
• Thus, percentage of literate population = (46/90) x 100 = 51.11%
Thus, option B is the correct answer.
Correct Answer: Option B
