  1. g = grandfathers age

    d = granddaughter age

    You have two conditions for a grandfather:

    g = 10 d

    g = d + 54

    Now:

    g = g

    10 d = d + 54 Subtract d to both sides

    10 d - d = d + 54 - d

    9 d = 54 Divide both sides by 9

    d = 54 / 9 = 6 yrs

    g = 10 d = 10 * 6 = 60 yrs

    OR

    g = d + 54

    g = 6 + 54 = 60 yrs

    Their present ages:

    grandfather 60 yrs

    granddaughter 6 yrs
