    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 ā€“ Average wages is 250 Total wages = 400 Ɨ 250 = 1,00,000 Correct read = 160 + 440 = 600 Misread = 260 + 140 = 400 +Rs. 200 is the difference between correct salary and misread salary.
