Correct answer is '20920'. Can you explain this answer?
Verified Answer
Amal invests Rs 12000 at 8% interest, compounded annually, and Rs 1000...
The amount with Amal at the end of 1 year = 12000*1.08+10000*1.03*1.03=23569
Interest received by Amal = 23569-22000=1569 Let the amount invested by Bimal = 100b Interest received by Bimal  = 100b*7.5*1/100=7.5b
It is given that the amount of interest received by both of them is the same 7.5b=1569 b=209.2
Amount invested by Bimal = 100b = 20920

Amal invests Rs 12000 at 8% interest, compounded annually, and Rs 1000...
Understanding Amal's Investments
Amal makes two investments:
- Investment 1: Rs 12000 at 8% interest, compounded annually.
- Investment 2: Rs 10000 at 6% interest, compounded semi-annually.
Calculating Amal's Total Interest
1. For the first investment (compounded annually):
- Amount = Principal * (1 + Rate) ^ Time
- Amount = 12000 * (1 + 0.08) ^ 1 = 12000 * 1.08 = Rs 12960
- Interest = Amount - Principal = 12960 - 12000 = Rs 960
2. For the second investment (compounded semi-annually):
- Effective rate = 6% / 2 = 3% per half year
- Amount = Principal * (1 + Rate) ^ (2 * Time)
- Amount = 10000 * (1 + 0.03) ^ 2 = 10000 * 1.0609 = Rs 10609
- Interest = Amount - Principal = 10609 - 10000 = Rs 609
3. Total Interest for Amal:
- Total Interest = Interest from Investment 1 + Interest from Investment 2
- Total Interest = 960 + 609 = Rs 1569
Understanding Bimal's Investment
Bimal invests his money at 7.5% simple interest for one year. The formula for simple interest is:
- Simple Interest = Principal * Rate * Time
Setting Up the Equation
Since Bimal's interest equals Amal's total interest:
- 1569 = Principal * 0.075 * 1
Calculating Bimal's Investment
- Principal = 1569 / 0.075 = Rs 20920
Conclusion
Thus, the amount invested by Bimal is Rs 20920, matching the interest earned by Amal.
