Answer 2

$\boxed{\boxed{\boxed{\bold{\red{Solution : \longrightarrow}}}}}$

$\bold{Given,}$

$\bold{Population \: \: of \: \: the \: \: village \: (P) = 67000}$

$\bold{Rate \: \: of \: \: increase \: \: during \: \: {1}^{st} \: \: year \: (r) = 5\%.}$

$\bold{Rate \: \: of \: \: increase \: \: during \:\: {2}^{nd} \: \: year \:(q) = 4\%.}$

$\bold{\underline{Now}}$

$\bold{Population \: \: after \: \: 2 \: \: years}$

$\bold{= P \times (1 + \frac{r}{100} ) \times (1 + \frac{q}{100} ) }\\ \\\bold{ = 67000 \times (1 + \frac{5}{100} ) \times (1 + \frac{4}{100} )}$

$\bold{= 67000 \times \frac{105}{100} \times \frac{104}{100} }\\ \\ \bold{= 73164 }\: \: \:\boxed{\boxed{\boxed{\bold{\green {Ans}}}}}$
