    B 3.5% Correct Answer Incorrect Answer
    C 1.7% Correct Answer Incorrect Answer
    D 22.5% Correct Answer Incorrect Answer

    Solution

    ATQ, Total marks of D1, D2 and D4 = 80 + 70 + 75 = 225 Average marks of D1, D2 and D4 = 225/3 = 75 75 means 75% because the maximum marks of each subject are 100. Total marks of D3 and D5 = 50 + 55 = 105 Average marks of D1 and D5 = 105/2 = 52.5 Average percentage of D1 and D5 = 52.5% Required difference = 75% – 52.5% = 22.5%
