Find the amount .Rs. 2500 for 3 years at 12% per annum.

Answer

To find the total amount after 3 years for a principal of Rs. 2500 at an interest rate of 12% per annum, we can use the formula for calculating the amount (A) in simple interest:

\[ A = P + I \]

Where:
- \( A \) is the total amount after time \( t \),
- \( P \) is the principal amount,
- \( I \) is the interest earned.

First, we need to calculate the interest (I) using the formula:

\[ I = \frac{P \times R \times T}{100} \]

Where:
- \( I \) is the interest,
- \( P \) is the principal amount (Rs. 2500),
- \( R \) is the rate of interest (12%),
- \( T \) is the time (3 years).

### Step 1: Calculate the interest (I)

Substituting the values into the formula:

\[ I = \frac{2500 \times 12 \times 3}{100} \]

### Step 2: Perform the multiplication

First, calculate \( 2500 \times 12 \):

\[ 2500 \times 12 = 30000 \]

Now, multiply by 3:

\[ 30000 \times 3 = 90000 \]

### Step 3: Divide by 100 to find the interest

Now, divide by 100:

\[ I = \frac{90000}{100} = 900 \]

So, the interest earned over 3 years is Rs. 900.

### Step 4: Calculate the total amount (A)

Now, we can find the total amount (A) by adding the principal (P) and the interest (I):

\[ A = P + I \]

Substituting the values:

\[ A = 2500 + 900 \]

### Step 5: Perform the addition

\[ A = 3400 \]

Therefore, the total amount after 3 years is Rs. 3400.

### Final Answer:
The amount after 3 years is Rs. 3400.
