1)  

 Find the compound  interest on 3412 compounded half_ yearly for  32 years at the rate of 5% per annum.

Answer: 3674.35


SOLUTION 1 :

Given:

 P     =   3412

 r      =  5%

 n     =  18 months = 1812 years = 32 years

Amount after 32 months           =   P[ 1+(12(r /100))]2n

                                                    =  3412[ 1+(12x0.05) ](2x32)

                                                     =  3412[1+0.025](2x32)

                                                     =   3412(1.025)3

                                                     =  3412 x 1.08

                                                     =   3674.35



2)  

 Find the compound  interest on 1131 compounded half_ yearly for  32 years at the rate of 7% per annum.

Answer: 1253.96


SOLUTION 1 :

Given:

 P     =   1131

 r      =  7%

 n     =  18 months = 1812 years = 32 years

Amount after 32 months           =   P[ 1+(12(r /100))]2n

                                                    =  1131[ 1+(12x0.07) ](2x32)

                                                     =  1131[1+0.035](2x32)

                                                     =   1131(1.035)3

                                                     =  1131 x 1.11
