| Area | Male population | Percentage of literate female population | Difference between male and female population |
| 2010 | 2011 | 2010 | 2011 | 2010 | 2011 |
| A | 330 | 380 | 60% | 75% | 60 | 60 |
| B | 200 | 300 | 72% | 66% | 50 | 50 |
| C | 250 | 240 | 50% | 55% | 20 | 60 |
| D | 320 | 230 | 65% | 70% | 120 | 40 |
| E | 280 | 380 | 60% | 63% | 110 | 80 |
| F | 300 | 220 | 70% | 58% | 30 | 80 |
In 2011:
Illiterate female population in area D = 81
Then, total female population in area D = 81 x 100/(100 - 70) = 270
Now, literate female population in area D = 270 - 81 = 189
It is given that literate female population in area D and E are equal. Then,
Literate female population in area E = 189
Then, total female population in area E = 189 x 100/63 = 300
So, illiterate female population in area E = 300 - 189 = 111
Illiterate female population in area E is equal to the illiterate male population in area D. Then,
Illiterate male population in area D = 111
Literate male population in area D = 230 - 111 = 119
Then, ratio of literate male to female population in area D = 119: 189 = 17: 27
