Answer 2

$\large\green{\boxed{Solution : }}$

$\large\red{\boxed{Given}}$

$\blue{P} = \red{Rs} \: \: 8000$

$\blue{T} = 2 \: \: years$

$\blue{R} = 5\% \: \: p.a.$

$\underline\pink{Now}$

$\large\red{\boxed{A = P \times (1 + \frac{R}{100} ) {}^{T}}} \\ \\ \: \: \: \: = \red{Rs} \: \: 8000 \times (1 + \frac{5}{100} ) {}^{2} \\ \\ \: \: \: \: = \red{Rs} \: \: 8000 \times \frac{105}{100} \times \frac{105}{100} \\ \\ \: \: \: \: = \red{Rs }\: \: 8820$

$\large\pink{\boxed{CI = A - P}} \\ \\ \: \: \: \: \: = \red{Rs }\: \: (8820 - 8000) \\ \\ \: \: \: \: \: =\red{ Rs }\: \: 820 \: \: \large\blue{\boxed{ Ans}}$
