Question

A Web music store offers two versions of a popular song. The size of the standard version is

2.5
megabytes (MB). The size of the high-quality version is
4.1
MB. Yesterday, the high-quality version was downloaded four times as often as the standard version. The total size downloaded for the two versions was
4914
MB. How many downloads of the standard version were there?

Answer 1

2.5 MB + 4.1MB + 6.6 MB. 4914/6.6 = 744 total downloads. 744/5 = 148 standard downloads which leaves 595 high quality downloads. Therefore the answer is 148.
