1)  

A cost of  a computer is 12003. The company offers it in 48 months, but charges 9% interest. Find the monthly instalment the purchaser has to pay.

Answer: 1330


SOLUTION 1 :

Given  :

Cost of computer  = 12003

Interest                  = 9%

period                    = 48 months(4year)

Total interest         = (12003 x 9 x 4) ÷100

                                  =   51852.96

Total amount to be paid     = 51852.96 + 12003

                                           = 63855.96

Monthly instalment         = Total amount ÷ Number of months

                                            = 63855.96 ÷ 48

Monthly instalment       = 1330

Answer: 2742


SOLUTION 1 :

Given  :

Cost of computer  = 37107

Interest                  = 6%

period                    = 72 months(6year)

Total interest         = (37107 x 6 x 6) ÷100

                                  =   160302.24

Total amount to be paid     = 160302.24 + 37107

                                           = 197409.24

Monthly instalment         = Total amount ÷ Number of months

                                            = 197409.24 ÷ 72
