In an examination, there are 150 questions divided into three groups A, B and C such that
each group contains at least one question. Each question in group A carries 2 mark, each
question in group B carries 3 marks and each question in group C carries 5 marks. It is
known that the questions in group A together carry at least 40% of the total marks. If
group B contains 20 questions, then
A. C ≤ 21 B. C ≤ 31 C. C ≤ 41 D. C ≤ 51
