    solving inequalities

    Solving the following inequality for x


    Inserting the roots 0, 4 in the number line below and starting from the right with + since the leading coefficient is positive, we have the following sign diagram.
    ---(+)--------{0}---------(-)-------------{4}-------(+)---------
    So, the inequality holds for and and the only value from (A)-(D) which is between and is the value of .
    Therefore the correct answer is (C).
