1)  

 Find the difference between simple interest and compound interest on 17929 at 2 years at 4% per annum compounded annually

Answer: 29


SOLUTION 1 :

Given:

P      =   17929

n       = 2 years

r        = 4%

Difference between C.I and S.I for 2 years = P(r÷ 100)2

                                                                    = 17929(4÷100)2

                                                                    = 17929(0.04)2

                                                                    = 17929 x 0.0016

                                                                    = 29



2)  

 Find the difference between simple interest and compound interest on 18310 at 2 years at 4% per annum compounded annually

Answer: 29


SOLUTION 1 :

Given:

P      =   18310

n       = 2 years

r        = 4%

Difference between C.I and S.I for 2 years = P(r÷ 100)2

                                                                    = 18310(4÷100)2

                                                                    = 18310(0.04)2

                                                                    = 18310 x 0.0016

                                                                    = 29



3)  

 Find the difference between simple interest and compound interest on 14873 at 2 years at 2% per annum compounded annually
