    Answer: (3) 42

    Explanation:-
    The average age of mother and fer six children = 12 years
    Then, total age of mother and her children = 12 x 7
    = 84 years

    If the age of the mother is excluded then, average of age reduced by 5 years.
    Then, total age of children = (12 – 5) x 6
    = 7 x 6
    = 42 years

    So, the age of the mother = 84 – 42
    = 42 years

    Hence, the correct answer is option (3) 42 years.
