    Sia ? 6 years, 6 months ago

    Let Salim's present age be x years and his daughter's age be y years.
    Two years ago,
    Salim's age = (x - 2) years
    Daughter's age = (y - 2) years
    As per given condition
    Two years ago, Salim was thrice as old as his daughter .
     x - 2 = 3(y - 2)
    x - 2 = 3y - 6
    {tex}\Rightarrow{/tex} x - 3y = -4 .........(i)
    Six years hence,
    Salim's age = (x + 6) years
    Daughter's age = (y + 6) years
    As per second condition
    Six years later, he will be four years older than twice her age.
    x + 6 = 2(y + 6) + 4
    x + 6 = 2y + 12 + 4
    {tex}\Rightarrow{/tex} x - 2y = 10 ...........(ii)
    Subtracting (i) from (ii), we have
    x - 2y - x  + 3y =10 - ( -4)
    y = 14
    Put y = 14 in (i)
    {tex}\Rightarrow{/tex} x - 3(14) = -4
    {tex}\Rightarrow{/tex}  x - 42 = - 4
    {tex}\Rightarrow{/tex} x = 38
    Therefore, the present age of Salim is 38 years and that of his daughter is 14 years.
