    The average salary of 400 employees were found to be Rs.

    250. Later on, it was discovered that the wages of two workers were misread as 260 and 140 instead of 160 and 440. The correct average wages of the employees are:
    A 275.75 Correct Answer Incorrect Answer
    B 225.75 Correct Answer Incorrect Answer
    C 250.50 Correct Answer Incorrect Answer
    D 300 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    400 workers – Average wages is 250 Total wages = 400 × 250 = 1,00,000 Correct read = 160 + 440 = 600 Misread = 260 + 140 = 400 +Rs. 200 is the difference between correct salary and misread salary. So we will add this in 100000 and then divided by 400 and then find average wages Required Average = 100200/400  = 250.50
