After completing BE in civil engineering, M.Sc. in mathematics is not recommended. You should go for either M.Tech or MBA. You may do your M.Tech part time.

Hi,
MBA programs require work experience and in Ireland mostly you will find PGDM or MS Business programs for freshers. Talking about the distance education you had prior you have to write to the universities you plan applying to and find out. IGNOU degrees are generally recognised worldwide however always check with the concerned universities directly. Additionally, you must take your IELTS and/or GMAT.
