    Ananya’s average marks across 6 subjects were stated as

    64. Later, it was found that her marks in Physics and Geography were wrongly printed as 58 and 67, while the actual scores were 63 and 77. What is the corrected average?
    A 28.5 Correct Answer Incorrect Answer
    B 33.5 Correct Answer Incorrect Answer
    C 66.5 Correct Answer Incorrect Answer
    D 71.3 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Incorrect total marks = 64 × 6 = 384

    Correct total = 384 - (58 + 67) + (63 + 77) = 399

    Correct average = 399 ÷ 6 = 66.5
