Understanding the Problem
To find the rate of simple interest per annum, we can analyze the information given:
- The amount becomes 2400 in 4 years.
- The amount becomes 2500 in 5 years.
Calculating the Interest Earned
We can calculate the interest earned in the 5th year:
- Total amount after 5 years: 2500
- Total amount after 4 years: 2400
The interest earned in the 5th year is:
- Interest for 1 year = 2500 - 2400 = 100
Calculating Total Interest for 4 Years
Since the interest for 1 year is 100, the total interest earned in 4 years is:
- Total Interest in 4 years = 4 * Interest for 1 year = 4 * 100 = 400
Finding the Principal Amount
Now, we can find the principal amount (P):
- Amount after 4 years = Principal + Total Interest in 4 years
- 2400 = P + 400
- P = 2400 - 400 = 2000
Calculating Rate of Interest
Using the formula for simple interest:
- Simple Interest (SI) = (P * R * T) / 100
Where:
- SI = Total Interest earned in 4 years = 400
- P = Principal = 2000
- T = Time = 4 years
Plugging in the values:
400 = (2000 * R * 4) / 100
Solving for R:
- R = (400 * 100) / (2000 * 4)
- R = 5
Conclusion
The rate of interest per annum is:
- 5%
