Answer:
230 downloads
Explanation:
==>Given:
Standard Version size (SV) = 2.5 MB
High Quality Version size (HQV) = 4.6 MB
Download ratio of SV to HQV = 1:4
Total size downloaded by both versions = 4807 MB
==>Required:
No. of standard version downloads
==>Solution:
=>Find the total size of SV version downloaded
Ratio of download: SV:HQV = 1:4
Which means for every download 2.5MB (1*2.5) of SV made, 18.4MB (4*4.6) of HQV was made
Thus, SV:HQV = 2.5MB : 18.4MB
=>Total size of SV downloaded = 2.5/(2.5+18.4) * 4807
= 2.5/20.9 * 4807 = 575.0 MB
=>No. of standard version downloads = 575.0/2.5 = 230 downloads
