Face value = Rs. (50 x 20) = Rs. 1000.
Dividend = Rs. | ❨ | 27 | x | 1000 | ❩ | = Rs. 135. |

Rs. 12 is an income on Rs. 100.
∴ Rs. | 9 | is an income on Rs. | ❨ | 100 | x | 9 | ❩ | = Rs. 15. |

By investing Rs. 97, income = Rs. | ❨ | 128 | x 97 | ❩ | = Rs. 8. |
1552 |
∴ Dividend = 8%
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.
Number of shares = | ❨ | 4455 | ❩ | = 540. |

By investing Rs 96, income derived = Rs. 9/2
By investing Rs. 100, income derived = Rs. (9 x 100) / (2 x 96) = Rs.4.69
Interest obtained =4.69%
To earn Rs. 77, investment = Rs. 1100
To earn Rs. 11/2, investment = (1100 / 77) x (11/2) = Rs. 784/7
For an income of Rs. 4, stock needed = Rs. 100
For an income of Rs. 500, stock needed = Rs. (100 / 4) x 500 = Rs. 12500
For an income of Rs. 5, investment = Rs. 100
For an income of Rs. 4, investment = Rs. (100/5) x 4 = Rs. 80
For an income of Rs. 6, investment = Rs. 96.
For an income of Rs. 100, investment = Rs. (96 / 6) x 100 = Rs. 1600
