    Question

    A student scores an average of 55 marks in the first 4

    exams. To get an average of 70 marks over 8 exams, what should be his average score in the remaining exams?
    A 85 Correct Answer Incorrect Answer
    B 110 Correct Answer Incorrect Answer
    C 75 Correct Answer Incorrect Answer
    D 35 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Total marks required = 70 × 8 = 560

    Marks obtained in 4 exams = 55 × 4 = 220

    Required marks = 560 - 220 = 340

    Required average score in remaining exams = 340 ÷ 4 = 85 marks
