The numbers of illiterates is more than one lakh in:
exactly four cities
To find the number of cities where the count of illiterates is more than one lakh, we'll analyze the given data for each city.
- City A:
The number of persons = 5.0 lakh.
Literates : Illiterates ratio = 1 : 4.
Total parts = 1 + 4 = 5 parts.
Illiterates = \(\frac{4}{5}\) of 5.0 lakh = 4.0 lakh.
Illiterates are more than 1 lakh. - City B:
The number of persons = 3.6 lakh.
Literates : Illiterates ratio = 4 : 1.
Total parts = 4 + 1 = 5 parts.
Illiterates = \(\frac{1}{5}\) of 3.6 lakh = 0.72 lakh.
Illiterates are less than 1 lakh. - City C:
The number of persons = 2.8 lakh.
Literates : Illiterates ratio = 2 : 5.
Total parts = 2 + 5 = 7 parts.
Illiterates = \(\frac{5}{7}\) of 2.8 lakh = 2.0 lakh.
Illiterates are more than 1 lakh. - City D:
The number of persons = 4.5 lakh.
Literates : Illiterates ratio = 3 : 2.
Total parts = 3 + 2 = 5 parts.
Illiterates = \(\frac{2}{5}\) of 4.5 lakh = 1.8 lakh.
Illiterates are more than 1 lakh. - City E:
The number of persons = 5.0 lakh.
Literates : Illiterates ratio = 2 : 3.
Total parts = 2 + 3 = 5 parts.
Illiterates = \(\frac{3}{5}\) of 5.0 lakh = 3.0 lakh.
Illiterates are more than 1 lakh. - City F:
The number of persons = 3.0 lakh.
Literates : Illiterates ratio = 7 : 3.
Total parts = 7 + 3 = 10 parts.
Illiterates = \(\frac{3}{10}\) of 3.0 lakh = 0.9 lakh.
Illiterates are less than 1 lakh.
After analyzing each city, the cities with more than 1 lakh illiterates are A, C, D, and E. Thus, the number of cities with more than 1 lakh illiterates is exactly four cities.
