Answer: Option B
Explanation:
₹ 12 is an income on ₹ 100.
To obtain ₹ 10, investment = ₹ 96.
For an income of ₹ 8, investment = ₹ 100.
Market value of ₹ 100 stock = ₹ 75.
To earn ₹ 135, investment = ₹ 1620.
Market value of ₹ 100 stock = ₹ 96.
Let the investment in 9% stock be ₹ x.
Then, investment in 10% stock = ₹ (9800 - x).
24x = 9800 x 25 - 25x
49x = 9800 x 25
x = 5000.
Answer: Option C
Face value = ₹ (540 x 10) = ₹ 5400.
Answer: Option D
For an income of Re. 1 in 9% stock at 96, investment
For an income Re. 1 in 12% stock at 120, investment
Investment = ₹ [20 x (50 - 5)] = ₹ 900.
Face value = ₹ (50 x 20) = ₹ 1000.
To earn Rs. 1500, investment
Let investment in each case be ₹ (143 x 117).
