1)  

A cost of  a computer is 18807. The company offers it in 24 months, but charges 9% interest. Find the monthly instalment the purchaser has to pay.

Answer: 2476


SOLUTION 1 :

Given  :

Cost of computer  = 18807

Interest                  = 9%

period                    = 24 months(2year)

Total interest         = (18807 x 9 x 2) ÷100

                                  =   40623.12

Total amount to be paid     = 40623.12 + 18807

                                           = 59430.12

Monthly instalment         = Total amount ÷ Number of months

                                            = 59430.12 ÷ 24

Monthly instalment       = 2476

Total interest         = (34985 x 10 x 6) ÷100

                                  =   251892

Total amount to be paid     = 251892 + 34985

                                           = 286877

Monthly instalment         = Total amount ÷ Number of months

                                            = 286877 ÷ 72
