C Correct answer
Explanation

Total marks = 200 + 150 = 350. Required average = 50% of 350 = 175. Marks in English = 40% of 200 = 80. Marks needed in second exam = 175 - 80 = 95. Percentage = (95 / 150) * 100 = 63.33%.

AI explanation

By calculating marks from percentages, Gaurav scored 40 percent of 200 marks, which is 80 marks. To achieve an overall average of 50 percent across both exams, his total marks out of 350 must be 50 percent of 350, which equals 175 marks. He needs 175 minus 80, or 95 marks, in the second exam out of a maximum of 150 marks. Finding the percentage for this exam gives 95 divided by 150 multiplied by 100, resulting in 63.33 percent.
