1)  

 Find the difference between simple interest and compound interest on 13996 at 2 years at 4% per annum compounded annually

Answer: 22


SOLUTION 1 :

Given:

P      =   13996

n       = 2 years

r        = 4%

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

                                                                    = 13996(4÷100)2

                                                                    = 13996(0.04)2

                                                                    = 13996 x 0.0016

                                                                    = 22



2)  

 Find the difference between simple interest and compound interest on 12463 at 2 years at 2% per annum compounded annually

Answer: 5


SOLUTION 1 :

Given:

P      =   12463

n       = 2 years

r        = 2%

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

                                                                    = 12463(2÷100)2

                                                                    = 12463(0.02)2

                                                                    = 12463 x 0.0004

                                                                    = 5



3)  

 Find the difference between simple interest and compound interest on 14400 at 2 years at 4% per annum compounded annually
