Question

Debby spent 15% of her monthly income in her children's education, invested 20% in mutual funds , deposited 8% in a fixed deposit and used 37% for her expenses. She's left with a balance of ₹8000. What was the total that she invested in fixed deposit?

• A. ₹3200
• B. ₹4000
• C. ₹2440
• D. ₹4800

Answer 1

The correct option is A ₹3200

Let the total income be ₹x.
Total % going in investments and expenses = 15 + 20 + 8 + 37 = 80%
Total remaining = 100 - 80 = 20%
$\frac{20x}{100}=8000$
$\Rightarrow x=\frac{8000\times 100}{20}=₹40000$
Total invested in fixed deposit = 8% of ₹40000 = $\frac{8}{100}\times 40000$
= ₹3200
