    Answer: renu is 10 years old and her mother is 40 years old.

    Step-by-step explanation:

    let renu be x years old

    then her mother would be 4x years

    after 5 years her age would be x+5 years

    and her mother would be 3 (x+5)

    equating the ages

    3 (x+5) = 4x+5

    3x+15-5=4x

    3x+10=4x

    4x-3x=10

    x=10 years

    renu is 10 years old and her mother is 40 years old. after5 years renu would be 15 years and her mother would be 45 years old
