Explanation

Total marks = 180 + 150 = 330. Required total = 50% of 330 = 165. Marks in first paper = 30% of 180 = 54. Marks needed in second paper = 165 - 54 = 111. Percentage = (111/150)*100 = 74%.

AI explanation

The student needs an overall score of 50 percent across both papers, which have a total of 180 + 150 = 330 marks, so the target total score is 0.5 times 330 = 165 marks. In the first paper, the student scored 30 percent of 180 marks, which is 54 marks. The required score in the second paper is 165 - 54 = 111 marks, and to find the percentage on the 150-mark paper, the calculation is (111 / 150) times 100. This gives the required percentage as 74 percent.
