a sum of rs 10000 was borrowed on first march and repaid on 25th july of the same year at a interest rate on 5.5% of interest . what was the interest paid???

Given :

Principle amount P = Rs . 10000

Rate of interest

*r*= 5.5%

Time

*t*= 1

^{st}march to 25

^{th}july = total days = 31 + 30 + 31 + 30 +25 = 147 , So

Time

*t*in years = $\frac{147}{365}$

And we know

Simple interest = $\frac{P\times r\times t}{100}$

So,

Total interest paid = $\frac{10000\times 5.5\times {\displaystyle \frac{147}{365}}}{100}=\frac{10000\times 5.5\times {\displaystyle 147}}{100\times 365}=\frac{8085000}{36500}=$
