    C 8 years Correct Answer Incorrect Answer
    D 6.5 years Correct Answer Incorrect Answer

    Solution

    Let the present age of the daughter be x years, and the mother’s age is 4x years. After 12 years, the mother’s age will be 4x + 12, and the daughter’s age will be x + 12. Given: 4x + 12 = 2(x + 12) + 1. 4x + 12 = 2x + 24 + 1. 4x - 2x = 25 - 12. 2x = 13 x = 6.5 years.
