$\mathbf{Solutions}$ (Q. Nos. 146-150)
Data is arranged as follows
In the year 1990,
Adults = 20440,
Females = 53% of 20440 = 10833.2
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
Males = 52% of 30760 = 15995.2
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
= 8891.556
= 8892
Adult females below the age of 50 in 2000
= 48% of 22147.2
= 10630.656
=10631
Therefore, required ratio
8992 : 10631 = 1 : 1.18
