Answer:
6000
6615
Step-by-step explanation:
The total population of a village is 13,000
Let say Male = 1000M
Female = 13000 - 1000M = 1000(13 - M)
The number of males and females increases every year by 5% and 10% respectively
Males after 2 Years = 1000M ( 1 + 5/100)² = 1102.5M
Females after 2 Years = 1000(13 - M)(1 + 10/100)² = 1210(13 - M)
Total Population = 1102.5 + 1210(13 - M)
= 15730 - 107.5M
15730 - 107.5M = 15085
=> 107.5M = 645
=> M = 6
1000M = 6000
number of males in the village at Start = 6000
After 2 years = 6615
