I went for the bank, and banker told me loan interest is 5%, I wanted a loan of $12,000, for period of 5 years.

If the ratio is fixed annually be paid the total is 15,000, shot just 60 months a monthly a premium 250

Principal amount is $12000.00 and amount rate of interest is 5% for 5 years 

P=$12000

I=5%

Y=12000*5%=$600

i=$600*number of years is 5 ($600*5)=$3000

interest of 5 years is $3000.

So, what is the Question? You didn't asked anything :-) 

you will have to pay 229/month, total payment will equal 13724$

12600 / 5 years = 2520

monthly: 210

Question is not clear. Interest rate is reducing or simple?

If you're gonna pay annually at the end of each year, the annual payment will equal to $2771.7 and the total 5 payments will come to $13858.50. So the effective interest rate is gonna be %13.4 (high rate)

principal amount $12,000, interest 5%, period 5 years.

assuming that compounds annually,  the formula is Amount = Principle * ( 1 + rate /100) ^ no. of years

==>  A = 12000 * ( 1  +  5/100) ^ 5 

==>  A = 12000 * (1.05) ^5 = calculate it is the answer. Thanks.

Principal amount is $12000.00 and amount rate of interest is 5% for 5 years 

Yearly Interest=12000*5%=$600.

Usually it is paid monthly to the bank. So $50 have to be paid each month.
