lb equals 1 : 4 kg

    The alligation tic-tac-toe will have a structure like this:

    `[[31.6 %,\quad\quad\quad\quad, 5.6 pt],[\quad\quad\quad\quad,9.2 % , \quad\quad\quad\quad],[3.6 %,\quad\quad\quad\quad,22.4 pt]]`

    Therefore, 5.6 parts should be taken from the source of 31.6%, and 22.4 parts should be taken from the source of 3.6%.
    `therefore` the ratio will be `(5.6)/(22.4)` or `(5.6/5.6)/(22.4/5.6)` `=> 1` : `4`. Ans.
