At Music Outlet the regular price for a CD is d dollars. How many CDs can be purchased for m dollars when the CDs are on sale at 50% off the regular price?

when there is a sale rate of cd = 0.5d
So, we can purchase m/0.5d=2m/d CDs

o.5 d when we have sale.
Hence, we can purchase m/0.5d=2m/d cds

Is something missing in the question??

harsh.champ I think nothing is missing just for the cost which is not given in numbers but a constant 'm' so I think it's ok.
Well options would have been more fruitful and enjoying to solve the problems..

Price of a CD = d
Amount = m

No of CDs that can be purchased with 50% discount = m/(d*50/100) = 2*m/d

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
