Common solution:
Eight persons A, B, C, D, E, F, G and H were born on either the 5th or 24th of the months January, March, April, and May in the same year, but not necessarily in the same order.
A was born in the month having an even number of days. Two persons were born between A and H, who was born immediate before E.
| | | Case 1 | Case 2 |
| Dates | Months | Persons | Persons |
| 5th | January | | |
| 24th | | H | |
| 5th | March | E | H |
| 24th | | | E |
| 5th | April | A | |
| 24th | | | A |
| 5th | May | | |
| 24th | | | |
Two persons were born between B and G. B is neither the eldest nor the youngest person.
| | | Case 1 | Case 2 | Case 1a | Case 2a |
| Dates | Months | Persons | Persons | Persons | Persons |
| 5th | January | | | | |
| 24th | | H | B | H | G |
| 5th | March | E | H | E | H |
| 24th | | B | E | G | E |
| 5th | April | A | G | A | B |
| 24th | | | A | | A |
| 5th | May | G | | B | |
| 24th | | | | | |
One person was born between C and G.
Neither C nor D was born in May.
Thus, case 1, case 2 and case 2a are invalid.
| | | Case 1a |
| Dates | Months | Persons |
| 5th | January | |
| 24th | | H |
| 5th | March | E |
| 24th | | G |
| 5th | April | A |
| 24th | | C |
| 5th | May | B |
| 24th | | |
Therefore, the final arrangement is:
| Dates | Months | Persons |
| 5th | January | D |
| 24th | | H |
| 5th | March | E |
| 24th | | G |
| 5th | April | A |
| 24th | | C |
| 5th | May | B |
| 24th | | F |
C was born on the 24th April.
