    lets say we took m grams of the solution -
    strength of water = 0
    strength of solution before mixing = 24
    strength of solution after mixing = 24(1-1/3) = 2/3*24


    200 * 0 + m * 24 = (2/3)*24*(m+200)

    solve for m, m = 400 grams

    Just use the formula,

    p = (p1q1+p2q2)/(q1+q2) - where qn represent quantities and pn represent concentration

    P is hte final concentration after mixing
