The table shows the percentage distribution of the population (only male and female) according to Gender and Literacy.
| State | Percentage literate | Gender | |
| Literate | Illiterate | ||

| A | 55 | 5 : 6 | 4 : 5 |
| B | 72 | 1 : 1 | 3 : 2 |
| C | 78 | 4 : 3 | 3 : 2 |
The total population in state C, if the illiterate female count in state C is 4,40,000, is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5000000.
The ratio of illiterate males to females in state C = 3 : 2
The number of illiterate females in state C = 440000
Illiterate males = (440000/2) × 3 = 660000
Total illiterate population in State C = 660000 + 440000 = 1100000
78% of the population is literate in State C, which means 100% - 78% = 22% of the population is illiterate
Let the total population be P.
So, (22/100) × P = 1100000
⇒ P = 5000000
Therefore, the total population in state C is 5000000.
