    multiplied by 9, what will be the average of the resulting numbers?
    A 650 Correct Answer Incorrect Answer
    B 675 Correct Answer Incorrect Answer
    C 645 Correct Answer Incorrect Answer
    D 685 Correct Answer Incorrect Answer

    Solution

    ATQ,

    If the average of given numbers is 'k' and every number is multiplied by 'n', then the new average becomes 'n ├Ч k'.

    Hence, required average = 75 ├Ч 9 = 675.
