Question

)Find the simple interest on Rs.4500 at 8% per annum for 2 years. Also find the amount.

Answer 1

• The simple interest = Rs. 720.
• The amount = Rs. 5220.

Given :–

• Principle = Rs. 4500.
• Rate = 8% per annum.
• Time = 2 years.

To Find :–

• The simple interest.
• The amount.

Solution :–

We know that,

Simple interest = $\sf \dfrac{P \times R \times T}{100}$

We have,

• P = Rs. 4500.
• R = 8% per annum.
• T = 2 years.

Now, substitute all the given values in the formula of simple interest.

$\rightarrow \dfrac{4500 \times 8 \times 2}{100}$

$\rightarrow \dfrac{45 \cancel{00 }\times 8 \times 2}{1 \cancel{00}}$

$\rightarrow \dfrac{45 \times 8 \times 2}{1}$

$\rightarrow 45 \times 16$

$\rightarrow Rs . \: 720$

The simple interest is Rs. 720.

Now, we have to find the amount.

Amount = Principle (P) + Simple interest (S.I.)

We have,

• Simple interest = Rs. 720.
• Principle = Rs. 4500.

$\rightarrow 4500 + 720$

$\rightarrow Rs. \: 5220$

The amount is Rs. 5220.

Hence,

The simple interest is Rs. 720 and the amount is Rs. 5220.

Answer 2

Answer:

Simple Interest = 720

Amount = 5220

Step-by-step explanation:

Simple Interest = (Principal x Rate x Time) / 100

S.I= 4500 x 8 x 2/100 = 720

Amount = Principle (P) + Simple interest (S.I.)

                4500 x 720 = 5220
