Calculation of Simple Interest:
Let's assume that the correct interest rate is 7.5% and the incorrect rate is 5.7%.
Step 1:
Let's calculate the interest earned at the correct rate of 7.5% for the given principal amount of Rs. 90,500 and an unknown time period.
Simple Interest (SI) = (Principal * Rate * Time) / 100
SI = (90,500 * 7.5 * Time) / 100
Step 2:
Now, let's calculate the interest earned at the incorrect rate of 5.7% for the same principal amount of Rs. 90,500 and the same unknown time period.
SI = (90,500 * 5.7 * Time) / 100
Step 3:
The difference in amounts at maturity is given as Rs. 9,771. Therefore, we can write the equation as:
(90,500 * 7.5 * Time) / 100 - (90,500 * 5.7 * Time) / 100 = 9,771
Step 4:
Let's solve the equation further:
(90,500 * 7.5 * Time - 90,500 * 5.7 * Time) / 100 = 9,771
(90,500 * 1.8 * Time) / 100 = 9,771
(1,63,350 * Time) / 100 = 9,771
Step 5:
Now, let's solve for the unknown time period:
Time = (9,771 * 100) / 1,63,350
Time = 59700 / 163350
Time ≈ 0.365 years
Explanation of the Period:
The sum of Rs. 90,500 was invested for approximately 0.365 years. This means that Mr. X invested the money for around 4.38 months.
Conclusion:
Mr. X invested Rs. 90,500 in a post office at a simple interest rate of 7.5% per annum. However, the rate was wrongly taken as 5.7% per annum. The difference in amounts at maturity is Rs. 9,771. After solving the equation, we find that the sum was invested for approximately 0.365 years or around 4.38 months.
