1)  

 Find the difference between simple interest and compound interest on 15444 at 2 years at 3% per annum compounded annually

Answer: 14


SOLUTION 1 :

Given:

P      =   15444

n       = 2 years

r        = 3%

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

                                                                    = 15444(3÷100)2

                                                                    = 15444(0.03)2

                                                                    = 15444 x 0.0009

                                                                    = 14



2)  

 Find the difference between simple interest and compound interest on 19189 at 2 years at 5% per annum compounded annually

Answer: 48


SOLUTION 1 :

Given:

P      =   19189

n       = 2 years

r        = 5%

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

                                                                    = 19189(5÷100)2

                                                                    = 19189(0.05)2

                                                                    = 19189 x 0.0025

                                                                    = 48



3)  

 Find the difference between simple interest and compound interest on 17239 at 2 years at 4% per annum compounded annually
