    Answer:

    let the present age of mother be x and present age of daughter be 55-x

    after 16 years ago of both mother and daughter are :-

    mother’s age=x+16

    daughter’s age =55-x+16

    =71-x

    a/q

    after 16 years mother’s age will double

    her daughter age

    2(71-x)=x+16

    142-2x=x+16

    3x=142-16

    x=126/3

    x=42

    hence, mother’s present age is 42 years & daughter’s present age is 55-42=13 years

    now,

    after 5 years from the present the sum of their ages will be:-

    (42+5)+(13+5)

    47+18

    = 65 years
