उत्तर
The star will rise at 6 pm after a month. This is because each star rises or sets 4 minutes earlier every day. Thus, in a month, the total advancement in the rising time of a star = 4 x 30 = 120 min = 2 h
So, if a star rises at 8 pm today, it will rise before 2 h, i.e., at 6 pm after a month.
