Males = 47% of 20440 = 9606.8
Illiterates = 60% of 20440 = 12264
Literates = 40% of 20440 = 8176
50 above adults = 17% of 20440 = 3474.8
50 below adults = 83% of 20440 = 16965.2

In the year 2000.
Adults = 30760
Females = 48% of 30760 = 14764.8

50 below adults = 72% of 30760 = 22147.2
50 above adults = 28% of 30760 = 8612.8
Illiterates = 7000
Literates = 30760 - 7000 = 23760

(c) Adult females below the age of 50 in 1990
= 53% of 16965.2

Adult females below the age of 50 in 2000
= 48% of 22147.2
