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 C contains 8 questions and group B carries at least 20% of the total marks, which of the following best describes the number of questions in group B?
A 11 or 12 B 12 or 13
C 13 or 14 D 14 or 15
Since Group (C) contains 8 questions, the corresponding weightage will be 24 marks. This figure should be less than or equal to 20% of the total marks. Check from the options. Option (c) provides 13 or 14 questions in Group (B), with, a corresponding weightage of 26 or 28 marks. This means that number of questions in Group (A) will either be 79 or 78 and will satisfy the desired requirement.
