(D) The population growth follows the compound interest formula: $A = P(1 + \frac{r}{100})^n$.Here,the initial population $P = 15$ lakhs.The rate of increase $r = 10 \%$ per year.The time period $n = 2005 - 2003 = 2$ years.Substituting the values into the formula:$A = 15 	imes (1 + \frac{10}{100})^2$$A = 15 	imes (1 + 0.1)^2$$A = 15 	imes (1.1)^2$$A = 15 	imes 1.21$$A = 18.15$ lakhs.Therefore,the population in the year $2005$ was $18.15$ lakhs.

The population of a state increases by $10 \%$ every year. If its population in the year $2003$ was $15$ lakhs,what was its population in the year $2005$ (in lakhs)?
