Or​

Answer 1

Answer:

= 97920

Step-by-step explanation:

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.

Answer 2

Step-by-step explanation:

a=p (1+r/100)^n

1200000 ( 1+4/100)^2

1200000 ( 1+1/ 25)^2

1200000 ( 26/25)^ n

1200000 * 26/25

after the calculation

1,297,920

so the population after 2 year 1297920
