SOLUTION

Present value of plot = Rs. 640000
Increase $=5\%$ per half year
Period (n) = 2 years or 4 half years
$\therefore$ Value of plot after 2 years $=P{(1+\frac{R}{100})}^n$
$=Rs.640000{(1+\frac{5}{100})}^4$
$=Rs.640000{\left(\frac{21}{20}\right)}^4$
$=Rs.640000\times \frac{21}{20}\times \frac{21}{20}\times \frac{21}{20}\times \frac{21}{20}$
= Rs. 777924
