What is the difference betweencompound interests for 2 yearsand 3 years for Rs. 500 at 10%rate compounded annually?1 * 1052 260.503 505.504 165.509:43 AM

Answer»

<P>Step-by-step explanation:

QUESTION:-

What will be in the difference between compound INTEREST for 2 years and 3 years for ₹500 at 10% rate compounded annually ?

• ₹105

• ₹60.5

• ₹ 505.50

• ₹165.50

Answer:-

Given :-

• The principal is ₹500.

• The rate is 10% per annum.

• The time is 2 years and 3 years.

To find :-

Difference between compound interest of the above amount.

Process :-

Compound Interest for 1st case:-

P = ₹500

R (r) = 10%

T (n) = 2 years

$∴CI = P(1+ \frac{r}{100} {)}^{n} \\ \\ ⇒CI = 500 (1 + \frac{10}{100} {)}^{2} \\ \\ ⇒CI = 500 ( \frac{110}{100} {)}^{2} \\ \\ ⇒CI = 500× \frac{110}{100} × \frac{110}{100} \\ \\ ⇒CI = ₹605$

Compound Interest for 2nd case:-

P = ₹500

R (r) = 10%

T (n) = 3 years

$∴ CI = P (1+ \frac{r}{100} {)}^{n} \\ \\ ⇒CI = 500 (1+ \frac{10}{100} {)}^{3} \\ \\ ⇒CI = 500 ( \frac{110}{100} {)}^{3} \\ \\ ⇒CI = 500 × \frac{110}{100} × \frac{110}{100} \times \frac{110}{100} \\ \\ ⇒CI = ₹665.5$

Difference between Interests:-

= ₹( 665.5 - 605 )

= ₹ 60.5 (Ans)

────────────────────────────
