    ₹42,000. Later it was found that one employee’s salary was taken as ₹49,000 instead of ₹39,000, and another’s as ₹37,000 instead of ₹47,000. What is the correct average salary?
    A Rs.24,000 Correct Answer Incorrect Answer
    B Rs.52,000 Correct Answer Incorrect Answer
    C Rs.42,000 Correct Answer Incorrect Answer
    D Rs.37,000 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Correct average = {(30 × 42000) – 49000 – 37000 + 39000 + 47000}/30

    = {(1260000 – 86000 + 86000)}/30

    = 1260000 / 30

    = ₹42,000
