Answer 2

Your answer ————————————————————
Given,

$P = Rs \: \: \: 8000 \\ \\ R = 10\% \: \: p.a. \\ \\ T = 1 \frac{1}{2} \: \: years$

$Since \: \: compounded \: \: yearly$

$A = P \times (1 + \frac{R}{100} ) {}^{1} \times (1 + \frac{ \frac{1}{2} \times R }{100} )$

$\: \: \: = Rs \: \: 8000 \times (1 + \frac{10}{100} ) \times (1 + \frac{1 \times 10}{2 \times 100} ) \\ \\ \: \: \: = Rs \: \: 8000 \times (1 + \frac{1}{10} ) \times (1 + \frac{1}{20} ) \\ \\ \: \: \: = Rs \: \: (8000 \times \frac{11}{10} \times \frac{21}{20} )$

$\: \: \: = Rs \: \: 9240$

$CI = A - P \\ \\ \: \: \: \: \: = Rs \: \: (9240 - 8000) \\ \\ \: \: \: \: \: = Rs \: \: 1240$
