To determine if John went to the market yesterday, we need information about both the days John goes to the market and today’s day.
Statement I: John goes to the market every alternate day.
This tells us that John visits the market on alternate days, but it does not tell us the exact days he started going to the market. Without knowing the starting point, we cannot determine if he went yesterday.
Statement II: Today is Wednesday.
This gives us the information about today’s day but does not provide any information about when John goes to the market. Therefore, this statement alone is not sufficient to answer the question.
Combining both statements:
Even though we know that John visits the market on alternate days and that today is Wednesday, we still do not know whether his last visit was on Monday or Tuesday. Without knowing the exact starting point of his market visits, we cannot determine if he went to the market yesterday.
Conclusion: Since we still cannot answer the question definitively, the correct answer is (D) Neither statement I nor statement II are sufficient.
Business schools’ (B schools) curriculums are filled with group assignments and case competitions. Even when students have just joined the B schools, corporate houses try 38 to catch good talent early by promising them internships based on case competitions. These competitions involve solving the problems presented by the organizations, analyzing the challenges they currently face, and presenting solutions in a manner that convinces the organizations’ representatives.
For students who are just joining a B school, the capability to actually solve such problems is quite limited. Because of that, the corporate houses generally are more focused on the presentations made by groups. Hence, the groups that communicate better, most often, win these competitions.
