    A 72 Correct Answer Incorrect Answer
    B 56 Correct Answer Incorrect Answer
    C 25 Correct Answer Incorrect Answer
    D 65 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Sum of 10 quantities = 10 ├Ч 35 = 350

    New average of all the numbers = 35 ├Ч 1.1 = 38.5

    So, sum of 12 numbers = 38.5 ├Ч 12 = 462

    So, average of two new numbers = (462 - 350) ├╖ 2 = 56
