A cost of  a computer is 43911. The company offers it in 72 months, but charges 6% interest. Find the monthly instalment the purchaser has to pay.

Answer: 3245


SOLUTION 1 :

Given  :

Cost of computer  = 43911

Interest                  = 6%

period                    = 72 months(6year)

Total interest         = (43911 x 6 x 6) ÷100

                                  =   189695.52

Total amount to be paid     = 189695.52 + 43911

                                           = 233606.52

Monthly instalment         = Total amount ÷ Number of months

                                            = 233606.52 ÷ 72

Monthly instalment       = 3245

Answer: 1179


SOLUTION 1 :

Given  :

Cost of computer  = 13601

Interest                  = 7%

Total interest         = (13601 x 7 x 5) ÷100

                                  =   57124.2

Total amount to be paid     = 57124.2 + 13601

                                           = 70725.2

Monthly instalment         = Total amount ÷ Number of months

                                            = 70725.2 ÷ 60
