Question

the population of the village 2 years ago was 5000 if the annual growth in population during two successive year was at the rate of 5% and 7% respectively find the present population of the village

Answer 1

P =5000

Growth of first year = 5%

5% of 5000 = 5000× 5/100 = 250

Population after first year = 5000 + 250 = 5250

Growth of second year = 7%

7% of 5250 = 5250× 7/100 = 367.5

Population after second year = 5250 + 367.5 = 5617.5 ≈ 5618

Present population = 5618
