Total number of questions = 260 Number of questions answered correctly from 40% of the first 130 questions = 40/100 × 130 = 52 To score 60% in the test number of questions needed to be answered correctly = 60/100 × 260 = 156 Number of questions that are to be needed more = 156 - 52 = 104 % of questions = 104/130 × 100 = 80% Hence, option 4 is the correct answer. |
