B Correct answer
Explanation

Total attempted = 25+40+32+40+50 = 187. Correct answers = (0.8*25) + (0.6*40) + (0.5*32) + (0.8*40) + (0.98*50) = 20 + 24 + 16 + 32 + 49 = 141. Percentage = 141/187 = 75.4%.

AI explanation

Calculate the total number of questions attempted by summing the values for each section in the 2003 exam, which is 25 plus 40 plus 32 plus 40 plus 50, equaling 187. Next, find the number of correct questions by multiplying the attempted questions by the correct percentage for each section, then sum them: 20 plus 24 plus 16 plus 32 plus 49, equaling 141. To find the overall percentage, divide 141 by 187 and multiply by 100, which yields 75.4 percent.
