Answer:
मूल जनसंख्या = 30000
Step-by-step explanation:
Let the current population be x
A/q
x + 10% of x = x + 3000
=> x + 10/100 × x = x + 3000
=> x + x/10 = x + 3000
=> ( 10x + x )/10 = x + 3000
=> 11x/10 = x + 3000
=> 11x = 10 ( x + 3000)
=> 11x = 10x + 30000
=> 11x - 10x =30000
=> x = 30000
Hence, the population of the village is 30000 .
