1,40,62,000

1,40,65,200

1,40,56,200

1,40,62,500

- The population growth rate is 4% every decade.

- The formula to calculate the population from 2000 to 2030 is:

$P_{2030} = P_{2000} \times (1.04)^{3}$

- With $P_{2030} = 15, 818, 400$ , solve for $P_{2000}$ .

- Rearrange the formula:

$P_{2000} = \frac{15, 818, 400}{(1.04)^{3}}$

- Calculate $P_{2000} = \frac{15, 818, 400}{1.124864} \approx 14, 062, 500$

- Hence, Option 4: *1,40,62,500* is the accurate population in the year 2000.
