Mohan invested ₹5,000 in a bank which offered interest at the rate of 10% per year compounded semi-annually. How much amount will he get after 2 years? [Give your answer correct to the nearest integer value.] |
₹6,512 ₹6,320 ₹6,250 ₹6,078 |
₹6,078 |
Interest is compounded half - yearly, Actual rate of interest = \(\frac{10}{2}\)% = 5% From the formula for compound interest, we know, Amount = P(1+$\frac{R}{100})^t$ = 5000 [ 1 + \(\frac{5}{100}\) ]4 = 5000 [ \(\frac{21}{20}\) × \(\frac{21}{20}\) × \(\frac{21}{20}\) × \(\frac{21}{20}\) ] = 5000 [ \(\frac{ 194481}{160000}\) ] = 6077.53 = 6078 ( nearest integer value )
