= Principal amount = Rs.20,000

= Rate of interest = 5%

= Time = 3 years


2. Calculate the interest:



\text{Interest} = \frac{20000 \times 5 \times 3}{100} = 3000.

Answer:
The interest earned in 3 years is Rs. 3000.

Question:
A bank offers a simple interest rate of 6% per annum. If a customer deposits Rs. 25,000 for 4 years, what is the total simple interest earned over that period?

Solution:

1. Identify the formula for Simple Interest (SI):



\text{SI} = \frac{P \times R \times T}{100}

is the principal (Rs. 25,000)

is the rate of interest (6%)

is the time period (4 years)


2. Substitute the values into the formula:



\text{SI} = \frac{25000 \times 6 \times 4}{100}

3. Calculate the interest:



\text{SI} = \frac{25000 \times 24}{100} = \frac{600000}{100} = 6000.

Answer:
The total simple interest earned over 4 years is Rs. 6,000.

2. Use the formula for the nth term of an arithmetic progression:



a_n = a_1 + (n - 1)d

3. Substitute :



a_8 = 105 + (8 - 1) \times 10 = 105 + 70 = 175.

Answer:
The 8th transaction amount is 175.
