a) 3672
b) 3772
c) 3872
d) 3972​

Answer 1

Answer:

Now Compound interest = A - P ⇒ Compound interest = Rs. 15972 - Rs. 12000 = Rs. 3972

Step-by-step explanation:

Answer 2

Answer:

Given :-

Rs 12000 for 3 years at 10% per annum compounded annually.

To Find :-

What is the compound interest.

Formula Used :-

❶ To find amount (A) we know that,

$\boxed{\bold{\large{Amount\: =\: P(1 + \dfrac{r}{100})^{n}}}}$

❷ To find the compound interest, we know that,

$\large\green{\underline{{\boxed{\textbf{C.I\: =\: Amount\: -\: Principal}}}}}$

C.I=Amount-Principal

Solution:-

Given :

Principal (P) = Rs 12000

Rate of Interest (r%) = 10 %

Time (n) = 3 years

❶ First we have to find the amount,

⇒$Amount = P( 1 + \dfrac{r}{100}$

⇒ Amount = 12000

⇒ Amount = 12000

⇒ Amount = 12 × 11 × 11 × 11

⇒ Amount = Rs 15972

❷ Now, we have to find the compound interest,

⇒ C.I = 15972 - 12000

➠ $\small\bf{\underbrace{\blue{C.I\: = Rs\: 3972}}}$

C.I=Rs3972

\therefore∴ The compound interest will be $\small{\red{\bold{\underline{Rs\: 3972}}}}$

Rs3972

. Correct options will be the option no (d) ☑.
