    The average of series 'S3', which consists of 6 consecutive

    even numbers, is 33. The second term of series 'T3', which consists of 5 consecutive odd numbers, is 5 more than the first term of series 'S3'. Find the average of series 'T3'.
    A 33 Correct Answer Incorrect Answer
    B 34 Correct Answer Incorrect Answer
    C 35 Correct Answer Incorrect Answer
    D 36 Correct Answer Incorrect Answer
    E 37 Correct Answer Incorrect Answer

    Solution

    Let six consecutive even numbers be 'a', (a + 2), (a + 4), (a + 6), (a + 8) and (a + 10), respectively.

    ATQ,

    a + a + 2 + a + 4 + a + 6 + a + 8 + a + 10 = 33 X 6

    Or, 6a = 198 - 30

    So, 'a' = (168 / 6) = 28

    So, 2nd term of series 'T3' = 28 + 5 = 33

    So, series 'T3' = 31, 33, 35, 37, 39

    Therefore, required average = (31 + 33 + 35 + 37 + 39) ├╖ 5 = 35
