If each shelf is to contain exactly 3 new CDs and there are only 5 shelves, only 15 can be placed in the rack. So, the answer to the second question is no. The same goes for the first question as placing 3 or fewer CDs to the shelves will make the rack insufficient for the CDs.
120 ÷ 4= 30 so 30 pages a day

The solution for this problem is:
<span>Let time taken by Emily be x </span>
<span>
then Aileen take 2/3 of x = 2x/3 </span>
<span>
1 min work of Emily = 1/x</span>
<span>
1 min work of Aileen = 1/ 2x/3 => 3/2x</span>
<span>
1 min work of both = 1/45</span>
<span>
1/x + 3/2x = 1/45</span>
<span>
5/2x = 1/45</span>
<span>
1/x = 2/225</span>
<span>
Emily take 225/2 mins to complete the work, then Aileen</span>
<span>= 225/2*2/3</span>
<span>= 75 mins.</span>
