CAT-2004-Previous Years Paper
In an examination, there are 100 questions divided into three groups A, B and C, such that each group contains at least one question. Each question in group A carries 1 mark, each question in group B carries 2 marks and each question in group C carries 3 marks. It is known that the questions in group A together carry at least 60% of the total marks.
If group B contains 23 questions, then how many questions are there in group C?
A 1 B 2 C 3 D Cannot be determined
Since Group (B) contains 23 questions, the marks associated with this group are 46. Now check for option (1). If Group (C ) has one question, then marks associated with this group will be 3. This means that the cumulative marks for these two groups taken together will be 49. Since total number of questions are 100, Group (A) will have 76 questions, the corresponding weightage being 76 marks. This satisfies all conditions and hence is the correct option. It can be easily observed that no other option will fit the bill.
