A cost of  a computer is 33349. The company offers it in 36 months, but charges 10% interest. Find the monthly instalment the purchaser has to pay.

Answer: 4261


SOLUTION 1 :

Given  :

Cost of computer  = 33349

Interest                  = 10%

period                    = 36 months(3year)

Total interest         = (33349 x 10 x 3) ÷100

                                  =   120056.4

Total amount to be paid     = 120056.4 + 33349

                                           = 153405.4

Monthly instalment         = Total amount ÷ Number of months

                                            = 153405.4 ÷ 36

Monthly instalment       = 4261

                                  =   48514.8

Total amount to be paid     = 48514.8 + 40429

                                           = 88943.8

Monthly instalment         = Total amount ÷ Number of months

                                            = 88943.8 ÷ 24
