Simple Interest Worksheet (Class 7)

Part 1: Fill in the Blanks

1. The formula for calculating Simple Interest is __________.
2. In the formula for Simple Interest, P stands for __________, R stands for __________, and T stands for __________.
3. Simple Interest is calculated on the __________ amount.
4. The total amount (A) after interest is given by __________.
5. If the principal is ₹5000, the rate of interest is 5%, and the time is 2 years, the simple interest will be __________.

Part 2: True or False

1. Simple Interest is calculated on the initial principal only. (True / False)
2. Simple Interest increases as the time period increases. (True / False)
3. The amount after interest will be greater than the principal. (True / False)
4. Simple Interest is the same every year for the same principal, rate, and time. (True / False)
5. If the rate of interest is 0%, no interest will be charged. (True / False)

Part 3: Calculate the Simple Interest

Use the formula:
Simple Interest (SI) = (P × R × T) / 100

1. Principal = ₹2000, Rate = 4%, Time = 3 years.
   Calculate the simple interest.

2. Principal = ₹1500, Rate = 6%, Time = 5 years.
   Calculate the simple interest.

3. Principal = ₹5000, Rate = 8%, Time = 2 years.
   Calculate the simple interest.

4. Principal = ₹10000, Rate = 5%, Time = 4 years.
   Calculate the simple interest.

5. Principal = ₹7500, Rate = 7%, Time = 6 months.
   Calculate the simple interest.

Part 4: Find the Total Amount (Principal + Interest)

1. Principal = ₹3000, Rate = 5%, Time = 3 years.
   Find the total amount after interest.

2. Principal = ₹1200, Rate = 10%, Time = 2 years.
   Find the total amount after interest.

3. Principal = ₹8000, Rate = 4%, Time = 5 years.
   Find the total amount after interest.

4. Principal = ₹15000, Rate = 3%, Time = 4 years.
   Find the total amount after interest.

5. Principal = ₹2500, Rate = 6%, Time = 1 year.
   Find the total amount after interest.

1. Rohit borrowed ₹3000 from a bank at a rate of 6% per annum for 2 years.
   Calculate the simple interest he has to pay after 2 years.

2. Rina invested ₹2000 in a fixed deposit for 3 years at an interest rate of 7%.
   Find the total interest she will earn.

3. A person invested ₹10000 in a savings account for 5 years at an interest rate of 4%.
   What will be the simple interest earned after 5 years?

4. A man took a loan of ₹8000 at an interest rate of 5% per annum for 4 years.
   What will be the total interest he has to pay?

5. A sum of money was invested for 2 years at 9% per annum and earned ₹360 as interest.
   What was the principal amount?

Answers:

Part 1: Fill in the Blanks

1. SI = (P × R × T) / 100
2. P stands for Principal, R stands for Rate of interest, and T stands for Time in years.
3. Principal
4. A = P + SI
5. ₹500

Part 2: True or False

1. True
2. True
3. True
4. True
5. True

Part 3: Simple Interest Calculations

1. SI = (2000 × 4 × 3) / 100 = ₹240
2. SI = (1500 × 6 × 5) / 100 = ₹450
3. SI = (5000 × 8 × 2) / 100 = ₹800
4. SI = (10000 × 5 × 4) / 100 = ₹2000
5. SI = (7500 × 7 × 0.5) / 100 = ₹262.50

Part 4: Total Amount Calculations

1. A = 3000 + (3000 × 5 × 3) / 100 = ₹3450
2. A = 1200 + (1200 × 10 × 2) / 100 = ₹1440
3. A = 8000 + (8000 × 4 × 5) / 100 = ₹9600
4. A = 15000 + (15000 × 3 × 4) / 100 = ₹18000
5. A = 2500 + (2500 × 6 × 1) / 100 = ₹2650

Part 5: Word Problems

1. SI = (3000 × 6 × 2) / 100 = ₹360
2. SI = (2000 × 7 × 3) / 100 = ₹420
3. SI = (10000 × 4 × 5) / 100 = ₹2000
4. SI = (8000 × 5 × 4) / 100 = ₹1600
5. P = (360 × 100) / (9 × 2) = ₹2000
