Correct answer: A
Step-by-Step Solution
Calculate marks obtained in science:
The student got 32% of 300 marks.
Marks = 0.32 * 300 = 96 marks.
Determine the total marks needed for 50%:
Total marks for both subjects = 300 (science) + 200 (literature) = 500 marks.
Target 50% = 0.50 * 500 = 250 marks.
Calculate the marks required in literature:
Marks needed in literature = Total target marks - Science marks
Marks needed = 250 - 96 = 154 marks.
Calculate the percentage required in literature:
Percentage = (Marks needed in literature / Total literature marks) * 100
Percentage = (154 / 200) * 100 = 77%.
