Hello

In India in most of the institutes (almost all) you need to do a 4 year BSc programme to be eligible for doing MTech however you can persue your mtech degree abroad. From Indian point of view as well as from getting a job point of view, going for an MBA is a better choice. The salary of the two fields vary largely on an average too with MBA graduates earning more. MBA is a two year course and to get enrolled in any of the good institutes you will need to give either CAT or XAT. Besides this, most institutes have their own entrance exams too. For MTech in India in any good institute you will have to appear for GATE.
