Interest is compounded half - yearly, Actual rate of interest = \(\frac{10}{2}\)% = 5% From the formula for compound interest, we know, C.I = P(1+$\frac{R}{100})^t$– P = 160000 [ 1 + \(\frac{5}{100}\) ] - 160000 = 160000 [ \(\frac{21}{20}\) × \(\frac{21}{20}\) × \(\frac{21}{20}\) × \(\frac{21}{20}\) - 1 ] = 160000 [ \(\frac{ 194481 }{160000}\) - 1 ] = 160000 [ \(\frac{34481}{160000}\) ] = Rs. 34481 |
