Answer:
Population after 3 years =
10000 (1 + 10 / 100 ) ( 1 + 20 / 100 ) ( 1 - 5 / 100 )
= 10000 multiply 11 / 10 multiply 6 / 5 multiply 19 / 20
= 12540

the population of the village in the beginning (p) = 10,000
Step-by-step explanation:
given
rate (R) = 5%
people migrated = 1025
the population of the village (pt) = 10,000
time (T) = 2yrs
we know,
pt = p(1+R\100)^T - people migrated
10000 = p(1+5\100)^2 - 1025
10000+1025 = p(1.05)^2
11,025 = 1.1025 p
p = 10,000
the population of the village in the beginning (p) = 10,000
