Rs. 9800 are invested partly in 9% stock at 75 and 10% stock at 80 to have equal amount of incomes. The investment in 9% stock is:
Answer: Option
Explanation:
Let the investment in 9% stock be Rs. x.
Then, investment in 10% stock = Rs. (9800 - x).
| 9 | x x = | 10 | x (9800 - x) |
| 75 | 80 |
 |
3x | = | 9800 - x |
| 25 | 8 |
24x = 9800 x 25 - 25x
49x = 9800 x 25
x = 5000.
