    Answer:

    84 years

    Step-by-step explanation:

    Given :

    At present :

    Let :

    daughter’s age = x

    Woman’s age = 2x

    21 years ago :

    Woman’s age = 3 times daughter’s age

    2x – 21 = 3(x – 21)

    2x – 21 = 3x – 63

    -21 + 63 = 3x – 2x

    42 = x

    Daughter’s age = 42

    Woman’s age = 2x = 84

    Hence, woman’s present age is 42 years
