Looking at the horoscope of your wife, I see that her ascendant is at 1 degrees and 26 minutes. What that means is that her horoscope will change completely in 6 -8 minutes, because 1 degree is 4 minutes. As your wife suggest that her time of birth is 15:00. I will not be surprised that it is an approximate time of birth and not an accurate one. This is called a Rasi Sandhi when a person is born at the Cusp or when the ascendant is changing.
Going by this we see Saturn in the Lagan in transit which is one of the main reasons for her restlessness. Doing the remedies below will provide relief.
1. Read Hanuman Chalisa as before
2. Wear Pearl in Silver on her right hand ring finger on Monday Morning
