A lady spent 10% of her salary on bonds, 15% of the remaining salary on groceries, and gave ₹30,600 to her husband. Find the difference between the amount spent on groceries and bonds.

1. Rs. 1800
2. Rs. 1400
3. Rs. 2000
4. Rs. 1200

Correct answer: Rs. 1400

Solution

Let salary = S. Bonds = 0.1S. Remaining after bonds = 0.9S. Groceries = 15% of 0.9S = 0.135S. Given to husband = S - 0.1S - 0.135S = 0.765S = 30600 → S = 40000. Bonds = ₹4000. Groceries = ₹5400. Difference = 5400-4000 = ₹1400.
