Question

Sakshi invests a part of Rs. 12,000 in 12% stock at Rs. 120 and the remainder in 15% stock at Rs. 125. If his total dividend per annum is Rs. 1360, how much does he invest in 12% stock at Rs. 120?

• A. Rs. 4000
• B. Rs. 4500
• C. Rs. 5500
• D. Rs. 6000

Answer 1

Answer: (A)

Rs. 4000

Let investment in 12% stock be Rs. x.
Then, investment in 15% stock = Rs. (12000 - x)
$\therefore \frac{12}{120}\times x+\frac{15}{125}\times (12000-x)=1360$
$\Rightarrow \frac{x}{10}+\frac{3}{25}(12000-x)=1360$
$\Rightarrow 5x+72000-6x=1360\times 50$
$\Rightarrow x=4000$
