    The average wage of 500 workers was found to be Rs. 200. Later on it was discovered that the wages of two workers were misread as 180 and 20 instead of 80 and 220. The correct average wage is

    A) Rs. 200.10                    

    B) Rs. 200.20

    C) Rs. 200.50                    

    D) Rs. 201.00

    Correct Answer: B

    Solution :

    Total wages of 500 workers \[=500\times 200=100000\] Now, according to question.             \[?=\frac{(100000-180-20+80+220)}{500}\]             \[=\frac{100100}{500}=Rs.\,200.20\]
