Question

Nikhila spent 5% of her monthly income in her children's education, invested 18% in shares , deposited 3% in a bank and used 44% for her expenses. She's left with a balance of ₹15000. What was the total that she invested in shares?

• A. ₹18000
• B. ₹9000
• C. ₹15000
• D. ₹12400

Answer 1

The correct option is B ₹9000

Let the total income be ₹x.
Total % going in investments and expenses = 5 + 18 + 3 + 44 = 70%
Total remaining = 100 - 70 = 30%
$\frac{30x}{100}=15000$
$\Rightarrow x=\frac{15000\times 100}{30}=₹50000$
Total invested in shares = 18% of ₹50000 = $\frac{18}{100}\times 50000$
= ₹9000
