The respective ratio of the present age of a mother and daughter is 7 ...
And daughter's age after 3 years?
Let's assume the present age of the mother is 7x and the present age of the daughter is x.
Four years ago, the age of the mother was 7x - 4 and the age of the daughter was x - 4.
According to the given ratio, (7x - 4) / (x - 4) = 19 / 1.
Cross-multiplying, we get 7x - 4 = 19(x - 4).
Expanding the equation, we get 7x - 4 = 19x - 76.
Subtracting 7x from both sides, we get -4 = 12x - 76.
Adding 76 to both sides, we get 72 = 12x.
Dividing both sides by 12, we get x = 6.
Therefore, the present age of the mother is 7 * 6 = 42 years old and the present age of the daughter is 6 years old.
After 3 years, the mother's age will be 42 + 3 = 45 years old and the daughter's age will be 6 + 3 = 9 years old. Answer: \boxed{45, 9}.
