Hassan borrowed 5000 with simple interest for five years. He paid an extra 500 then how much percent he pays per annum?

3.5%

None of these

Hassan borrowed Rs. 5000 for 5 years.

He paid an extra Rs. 500, which means he paid a total of Rs. 5000 (principal) + Rs. 500 (interest) = Rs. 5500.

Since he paid Rs. 500 as interest for 5 years, we can calculate the interest rate per annum (per year) as follows:

Interest = Rs. 500

Time = 5 years

Simple Interest (SI) = (Principal x Rate x Time) / 100

500 = (5000 x Rate x 5) / 100

Now, let's solve for Rate (interest rate per annum):

Rate = (500 x 100) / (5000 x 5)

= 2%

So, Hassan pays 2% interest per annum.
