sequences and series
PLEASE HELP ME WITH THE PROBLEM
A farmer buys a used tractor for Rs 12000. He pays Rs 6000 cash and agrees to
pay the balance in annual instalments of Rs 500 plus 12% interest on the unpaid
amount. How much will the tractor cost him?

Re: sequences and series
find the 12% interest for the first payment...
1) amt needed to pay
12000-6000
=6000
2) no. of installments
6000/500
=12
continue.... it should be obvious from here.
I shall be on leave until I say so...
