1)  

 Find the difference between simple interest and compound interest on 10338 at 2 years at 4% per annum compounded annually

Answer: 17


SOLUTION 1 :

Given:

P      =   10338

n       = 2 years

r        = 4%

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

                                                                    = 10338(4÷100)2

                                                                    = 10338(0.04)2

                                                                    = 10338 x 0.0016

                                                                    = 17



2)  

 Find the difference between simple interest and compound interest on 17744 at 2 years at 4% per annum compounded annually

Answer: 28


SOLUTION 1 :

Given:

P      =   17744

n       = 2 years

r        = 4%

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

                                                                    = 17744(4÷100)2

                                                                    = 17744(0.04)2

                                                                    = 17744 x 0.0016

                                                                    = 28



3)  

 Find the difference between simple interest and compound interest on 13318 at 2 years at 3% per annum compounded annually
