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?  Select:	A) 1	B) 2	C) 3	D) 4	E) 5
Explanation :   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, the marks associated with this group will be 3. Thus total marks will be 49.   total number of questions = 100, group (A) will have 76 questions, the corresponding weightage being 76 marks.   1nswer : 1
