Answer is Wrong!
Answer is Right!
The correct answer is (b).
The total age of the family three years ago was $6 \times 19 = 114$ years. The total age of the family now is $114 + 3 \times 6 = 126$ years. The total age of the family including the baby is $126 + 1 = 127$ years. The baby is 1 year old.
Option (a) is incorrect because 11/2 is not an integer.
Option (c) is incorrect because 2 is not an integer.
Option (d) is incorrect because the baby is 1 year old.
