A town has a present population of 2,40,000. Every year the population increases by a birth rate of 12% and decreases by a death rate of 7%. Find the population of the town at the end of 3 years.
Show answer & explanation
Correct answer: C
Explanation
Has been given :
Initial population = 240000
Birth rate = 12% increase
Death rate = 7% reduction
time = 3 years
According to the formula:
Net growth = 12% − 7% = 5% per year
Final population = 240000 × (1 + 5/100)³
= 240000 × (1.05)³
= 240000 × 1.157625 = 277830
