A cost of  a computer is 44222. The company offers it in 48 months, but charges 5% interest. Find the monthly instalment the purchaser has to pay.

Answer: 3132


SOLUTION 1 :

Given  :

Cost of computer  = 44222

Interest                  = 5%

period                    = 48 months(4year)

Total interest         = (44222 x 5 x 4) ÷100

                                  =   106132.8

Total amount to be paid     = 106132.8 + 44222

                                           = 150354.8

Monthly instalment         = Total amount ÷ Number of months

                                            = 150354.8 ÷ 48

Monthly instalment       = 3132

Total interest         = (42502 x 10 x 4) ÷100

                                  =   204009.6

Total amount to be paid     = 204009.6 + 42502

                                           = 246511.6

Monthly instalment         = Total amount ÷ Number of months

                                            = 246511.6 ÷ 48
