Simple Interest Calculation Problem
Given:
- Principal (P) = Rs. 600
- Amount (A) after 4 years at simple interest = Rs. 720
- Rate of interest (R) = ?
- Increased rate of interest (R') = R + 2%
To Find: Amount (A') after 4 years at the increased rate of interest
Solution:
We know that the formula for simple interest is:
- SI = (P * R * T) / 100
- A = P + SI
where SI is the simple interest, T is the time in years.
Using the above formula, we can find the rate of interest (R):
- SI = A - P = 720 - 600 = 120
- SI = (P * R * T) / 100
- 120 = (600 * R * 4) / 100
- R = 5%
Now, we can find the amount (A') at the increased rate of interest:
- R' = R + 2% = 5% + 2% = 7%
- SI' = (P * R' * T) / 100
- SI' = (600 * 7 * 4) / 100
- SI' = 168
- A' = P + SI'
- A' = 600 + 168
- A' = 768
Therefore, the amount after 4 years at the increased rate of interest is Rs. 768 (Option B).
Given:
- Principal (P) = Rs. 600
- Amount (A) after 4 years at simple interest = Rs. 720
- Rate of interest (R) = ?
- Increased rate of interest (R') = R + 2%
To Find: Amount (A') after 4 years at the increased rate of interest
Solution:
We know that the formula for simple interest is:
- SI = (P * R * T) / 100
- A = P + SI
where SI is the simple interest, T is the time in years.
Using the above formula, we can find the rate of interest (R):
- SI = A - P = 720 - 600 = 120
- SI = (P * R * T) / 100
- 120 = (600 * R * 4) / 100
- R = 5%
Now, we can find the amount (A') at the increased rate of interest:
- R' = R + 2% = 5% + 2% = 7%
- SI' = (P * R' * T) / 100
- SI' = (600 * 7 * 4) / 100
- SI' = 168
- A' = P + SI'
- A' = 600 + 168
- A' = 768
Therefore, the amount after 4 years at the increased rate of interest is Rs. 768 (Option B).
