1)  

 Find the difference between simple interest and compound interest on 18670 at 2 years at 2% per annum compounded annually

Answer: 7


SOLUTION 1 :

Given:

P      =   18670

n       = 2 years

r        = 2%

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

                                                                    = 18670(2÷100)2

                                                                    = 18670(0.02)2

                                                                    = 18670 x 0.0004

                                                                    = 7



2)  

 Find the difference between simple interest and compound interest on 15107 at 2 years at 2% per annum compounded annually

Answer: 6


SOLUTION 1 :

Given:

P      =   15107

n       = 2 years

r        = 2%

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

                                                                    = 15107(2÷100)2

                                                                    = 15107(0.02)2

                                                                    = 15107 x 0.0004

                                                                    = 6



3)  

 Find the difference between simple interest and compound interest on 16211 at 2 years at 3% per annum compounded annually

Answer: 15

                                                                    = 16211(3÷100)2

                                                                    = 16211(0.03)2

                                                                    = 16211 x 0.0009

                                                                    = 15
