In the birth chart of Boy Mars is placed in the second house from the lagna while in the Moon chart Mars is placed in first house from the Moon. Hence Boy is not Mangalik from the Birth Chart but Chandra Mangalik from the Moon Chart.
In the birth chart of Girl Mars is placed in the seventh house from the lagna while in the Moon chart Mars is placed in fourth house from the Moon. Hence Girl is Mangalik from the Birth Chart and also Chandra Mangalik from the Moon Chart.
The girl has full mangal dosha, while the boy is partial mangalik. Marriage can be considered between a full and partial manglik.
