Question 1175706

A lab technician needs to make 12 liters of 45% alcohol. How much of 40% alcohol and 60% alcohol must he mix to produce this?
<pre>He's WRONG!!
MORE of the 40% solution than the 60%, needs to be mixed. So, IGNORE these: <s>Most of the parts to use must be of the 60% alcohol.</s>
                                                                            <s>Use 3 liters of 40% alcohol and 9 liters of 60% alcohol.</s>
