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

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

$P = Rs \: \: 15625$

$R = 16\% \: \: p.a.$

$T = 9 \: \: months \\ \\ \: \: \: \:= \frac{9}{12} \: \: years \\ \\ \: \: \:\: = \frac{3}{4} \: \: years$

$\blue{\boxed{Now}}$

$\green{\boxed{A = P \times (1 + \frac{R}{4 \times 100} ) {}^{4T}}} \\ \\ \: \: \: \: \: = Rs \: \: 15625 \times ( 1 + \frac{16}{400} ) {}^{4 \times \frac{3}{4} } \\ \\ \: \: \: \: \: = Rs \: \: 15625 \times ( \frac{416}{400} ) {}^{3} \\ \\ \: \: \: \: \: = Rs \: \: 15625 \times \frac{416}{100} \times \frac{416}{100} \times \frac{416}{100} \\ \\ \: \: \: \: \: = Rs \: \: 17576$

$\pink{\boxed{CI = A - P }}\\ \\ \: \: \: \: \: \: \: = Rs \: \: (17576 - 15625) \\ \\ \: \: \: \: \: \: \: = Rs \: \: 1951 \: \: \red{\boxed{ Ans}}$
