The Brainliest Answer!

CI for the First Year = 270

So CI for the second year = 580.50 - 270.00 = 310.50

So Applying the formula

Rate = ( CI for the Second Year - CI for the First Year) * 100

___________________________________________

CI for the First Year

[Note: This Formula Only is Applicable For consecutive years]

So now

Rate =(310.50 - 270)*100

---------------------------

270

Rate =40.50 * 100

---------------

270

Rate =4050

-------

270

Rate = 15%

So now,

SI = PRT

-------

100

270=P*15*1

-----------

100

P = 270 * 100

------------

15 * 1

P = 27000

-----------

15

P = Rs 1800
