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?
Explanatory Answer
Method of solving this CAT DILR Question from Analytical Reasoning question
(c) If C has 8 question, it has 24 marks. Then if B has 12 question, A must have 80 questions. Percentage of marks in B = 24/128 = 18.75%, hence the first two choices are wrong since it must be 20%. If B has 13 questions, percentage = 26/129 > 20%, and if B has 14 questions, percentage = 28/130 > 20%.
