D was born in the month of June. Three people are born between B and D.
Case 1:
| | JANUARY | MARCH | MAY | JUNE |
| 7 | | | | |
| 15 | | B | | D |
Case 2:
| | JANUARY | MARCH | MAY | JUNE |
| 7 | | B | | D |
| 15 | | | | |
G is born immediately before B in the same month.
So case 2 is invalid.
Case 1:
| | JANUARY | MARCH | MAY | JUNE |
| 7 | | G | | |
| 15 | | B | | D |
Two people are born between G and A. C is born after A.
| | JANUARY | MARCH | MAY | JUNE |
| 7 | | G | | C |
| 15 | | B | A | D |
E is born after F. H is born after F but not in January.
| | JANUARY | MARCH | MAY | JUNE |
| 7 | F | G | H | C |
| 15 | E | B | A | D |
The number of people born after G is same as the number of people born before A.
