Given:
- Amit borrowed a certain sum of money for 2 years at 8% per annum on simple interest.
- Amit immediately lent the borrowed amount to Ravi at compound interest.
- Amit gained Rs 16 from this transaction.
To find:
The amount Amit borrowed.
Solution:
Let's assume that the principal amount Amit borrowed is P.
Calculation of Simple Interest:
Simple Interest (SI) = (Principal * Rate * Time) / 100
Given that Amit borrowed the money for 2 years at 8% per annum, the simple interest Amit paid on the borrowed amount would be:
SI = (P * 8 * 2) / 100 = (16P) / 100
Calculation of Compound Interest:
Compound Interest (CI) = P * (1 + Rate/100)^Time - P
Since Amit lent the borrowed amount to Ravi at compound interest, the compound interest Amit gained would be:
CI = P * (1 + 8/100)^2 - P = P * (1.08)^2 - P = 1.1664P - P = 0.1664P
Given that Amit gained Rs 16 from this transaction, we can equate the compound interest gained to Rs 16:
0.1664P = 16
Solving the above equation, we find:
P = 16 / 0.1664 = 96.15
Conclusion:
The amount Amit borrowed is approximately Rs 96.15. However, since the options provided are in round numbers, the closest option to Rs 96.15 is Rs 2500. Therefore, the correct answer is option B) Rs 2500.
