Answer 2

Answer:

(a) Here, Principal (P) = Rs. 10800, Time (n) = 3 years Rate of interest (R) = 12\ \frac{1}{2}\%=\frac{25}{2\%}

Amount(A) = P\left(1+\frac{R}{100}\right)^n

= 10800\left(1+\frac{1}{8}\right)^3=10800\left(\frac{9}{8}\right)^3

= 10800\times\frac{9}{8}\times\frac{9}{8}\times\frac{9}{8}

= Rs. 15,377.34

Compound Interest (C.I.) = A – P

= Rs. 10800 – Rs. 15377.34 = Rs. 4,577.34
