Answer 1

Answer:

Thus we can use the formula to calculate the increase in population over the year. Now let us substitute P = 12 lakh =12×105=12,00,000, R = 4% and n = 2. Thus we got the population of the town after 2 years as 12,97,920. Thus the increase in the population = 1297920 – 1200000 = 97920.
