Answer 1

Answer:

$\tt \: Rate\% \: at \: half \: yearly \: = \frac{10}{2} = 5\% \\ \\ \tt \: Time = 2 \: years \\ \\ \therefore \: \tt n = 4 \: years \\ \\ \tt \: Formula \: used- \\ \\ \longrightarrow \: \boxed{ A = P(1 + \frac{R}{100})^{2} And \: CI = A - P} \\ \\ \sf \: \longrightarrow A = P(1 + \frac{R}{100})^{4} \\ \\ \longrightarrow \sf \:A = 5000(1 + \frac{5}{100} ) ^{4} \\ \\\longrightarrow \sf \: A = 500 0 \times \frac{21}{20} \times \frac{21}{20} \times \frac{21}{20} \times \frac{21}{20 } \\ \\\longrightarrow \sf \:A = 6077 .53125 \\ \\ \bf \: CI = A - P \\ \\ \implies \: 1077.53125$
