1)  

A cost of  a computer is 12017. The company offers it in 24 months, but charges 10% interest. Find the monthly instalment the purchaser has to pay.

Answer: 1702


SOLUTION 1 :

Given  :

Cost of computer  = 12017

Interest                  = 10%

period                    = 24 months(2year)

Total interest         = (12017 x 10 x 2) ÷100

                                  =   28840.8

Total amount to be paid     = 28840.8 + 12017

                                           = 40857.8

Monthly instalment         = Total amount ÷ Number of months

                                            = 40857.8 ÷ 24

Monthly instalment       = 1702

                                  =   47223.12

Total amount to be paid     = 47223.12 + 28109

                                           = 75332.12

Monthly instalment         = Total amount ÷ Number of months

                                            = 75332.12 ÷ 24
