1)  

 Find the difference between simple interest and compound interest on 16480 at 2 years at 4% per annum compounded annually

Answer: 26


SOLUTION 1 :

Given:

P      =   16480

n       = 2 years

r        = 4%

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

                                                                    = 16480(4÷100)2

                                                                    = 16480(0.04)2

                                                                    = 16480 x 0.0016

                                                                    = 26



2)  

 Find the difference between simple interest and compound interest on 14669 at 2 years at 2% per annum compounded annually

Answer: 6


SOLUTION 1 :

Given:

P      =   14669

n       = 2 years

r        = 2%

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

                                                                    = 14669(2÷100)2

                                                                    = 14669(0.02)2

                                                                    = 14669 x 0.0004

                                                                    = 6



3)  

 Find the difference between simple interest and compound interest on 14212 at 2 years at 3% per annum compounded annually
