hello aspirant,

you dont need to worry about part b questions. as you are going to apply for mba entrance there will be only one paper. For programs such as Integrated Courses/B.Voc./MBA/MCA/LLB or any other general course(s), there will be only one paper consisting  of 100 MCQs.  questions will be formed on subjects- like English Language, Reasoning, Data Interpretations/ Numerical Ability, General Awareness and Analytical Skills. follow any good aptitude books like r.s agarval , arun sharma will be enough. also solve previous years question papes.
