1)  

 Find the difference between simple interest and compound interest on 15756 at 2 years at 2% per annum compounded annually

Answer: 6


SOLUTION 1 :

Given:

P      =   15756

n       = 2 years

r        = 2%

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

                                                                    = 15756(2÷100)2

                                                                    = 15756(0.02)2

                                                                    = 15756 x 0.0004

                                                                    = 6



2)  

 Find the difference between simple interest and compound interest on 13480 at 2 years at 4% per annum compounded annually

Answer: 22


SOLUTION 1 :

Given:

P      =   13480

n       = 2 years

r        = 4%

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

                                                                    = 13480(4÷100)2

                                                                    = 13480(0.04)2

                                                                    = 13480 x 0.0016

                                                                    = 22



3)  

 Find the difference between simple interest and compound interest on 10372 at 2 years at 3% per annum compounded annually
