Question

Find the compound interest at the rate of 10% per annum for two years on that
principal which in two years at the rate of 10% per annum gives Rs 200 as simple
interest.​

Answer 1

Answer:

Rs. 210

Step-by-step explanation:

Okay here we need to find out the principal from the second situation where

S. I = 200

T= 2 years

R= 10%

As you know,

P = S. I X 100/ R X T

So,

= 200 X 100/ 10x2

P = Rs. 1000

Now,

To calculate C. I let's calculate the interest for two different years.

Interest for 1st year = PxRxT/100

=1000x 10x 1/100

= Rs. 100

Principal for 2nd year will 1100 because we add the interest to the original principal to calculate the interest for next year.

Now,

Interest for 2nd year = PxRxT/100

= 1100x10x1 / 100

= Rs. 110

So the total interest is 100+110

which is Rs. 210.
