(A) Let the population $3$ years ago be $P$.Given that the annual growth rate $r = 10 \%$ and the current population $A = 1,331,000$ after $n = 3$ years.The formula for population growth is $A = P \left(1 + \frac{r}{100}ight)^n$.Substituting the values: $1,331,000 = P \left(1 + \frac{10}{100}ight)^3$.$1,331,000 = P \left(1 + 0.1ight)^3$.$1,331,000 = P \left(1.1ight)^3$.$1,331,000 = P 	imes 1.331$.$P = \frac{1,331,000}{1.331} = 1,000,000$.Thus,the population $3$ years ago was $1,000,000$.

The population of Delhi increases by $10 \%$ every year. If the current population of Delhi is $1,331,000$,what was its population $3$ years ago?
