1)  

 Find the difference between simple interest and compound interest on 14167 at 2 years at 2% per annum compounded annually

Answer: 6


SOLUTION 1 :

Given:

P      =   14167

n       = 2 years

r        = 2%

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

                                                                    = 14167(2÷100)2

                                                                    = 14167(0.02)2

                                                                    = 14167 x 0.0004

                                                                    = 6



2)  

 Find the difference between simple interest and compound interest on 15502 at 2 years at 5% per annum compounded annually

Answer: 39


SOLUTION 1 :

Given:

P      =   15502

n       = 2 years

r        = 5%

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

                                                                    = 15502(5÷100)2

                                                                    = 15502(0.05)2

                                                                    = 15502 x 0.0025

                                                                    = 39



3)  

 Find the difference between simple interest and compound interest on 17613 at 2 years at 4% per annum compounded annually

                                                                    = 17613(4÷100)2

                                                                    = 17613(0.04)2

                                                                    = 17613 x 0.0016

                                                                    = 28
