Bank Discount

Hi!Today i learn about bank discount.it is not a difficult subject,u just have to do some calculation and then you get the answer.For example,if i want to borrow Rm 5000 for a year from my bank that charges a 12% discount rate.The bank will take Rm 5000 x 12%=Rm600 as interest in advance and i will receive Rm 4400 as proceeds.It must be noted that i will have to pay Rm 5000 at the end of one year.In such a case i will receive Rm 5000 but has to pay more than Rm 5000 at the end of one year.So it just not fair but i cannot sue the bank because i did not think it carefully when i borrow the money...
