Question

On what sum of money will the difference between the simple interest and compound interest for 2 years at 5% per annum to be equal to rs 50?​

Answer 1

Answer:

The difference between the Compound Interest and Simple Interest for a Principal of 'P' and rate of interest “I" is given by the formula

C.I- S.I for 2- years= P(I/100)²

here P= ?

Rate of interest I= 5%

C.I -S.I = Rs 50

So 50= P (5/100)²

So P= 50/(5/100)²

Principal = Rs 20,000

Answer 2

Answer:

Answer:

20,000 rs.

Step-by-step explanation:

let p is the sum of money.

as we know the formula

difference in simple interest and compound interest for 2 years=

\begin{gathered}p*(\frac{r}{100})^{2}\\\\50=p*(\frac{5}{100})^{2}\\\\50=p*\frac{1}{400}\\\\p=20000\end{gathered}

p∗(

100

r

)

2

50=p∗(

100

5

)

2

50=p∗

400

1

p=20000

so sum of money is 20,000 rs.
