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.
