Percentages Question 3 - CAT 2025
Question
Kamala divided her investment of Rs. 100000 between stocks, bonds, and gold. Her investment in bonds was 25% of her investment in gold. The annual returns were 10% on stocks, 6% on bonds, and 8% on gold. She earned a total return of Rs. 8200 in one year.
The amount, in rupees, that she gained from the bonds, was:
Step-by-Step Explanation
Let the investment in Gold be G.
Then,
- Bonds = 0.25G
- Stocks = 100000 − 1.25G
Using the total annual return,
10%S + 6%B + 8%G = 8200
Substituting the values,
10000 − 0.03G = 8200
G = 60000
Therefore,
B = 15000
Gain from bonds,
6% × 15000 = 900
Hence, the gain from bonds is Rs. 900.
💡 FundaMakers Tip: Express every investment in terms of one variable before forming the return equation. It makes the calculations much easier.
