3200 was total male population of the village at beginning of 2001
Step-by-step explanation:
the total population of a village was 8800 at the beginning of 2001
Male = M
Female = 8800 - M
Males increased by 12%
= (12/100)M = 0.12M
Females increased by 15%
= (15/100)(8800 -M )= 1320 - 0.15M
0.12M + 1320 - 0.15M = 10024 - 8800
=> 1320 - 0.03M = 1224
=> 0.03M = 96
=> M = 3200
total male population of the village at beginning of 2001= 3200
