Answer: A. 6 Web pages can be downloaded

Explanation: Given in the Question is a bandwidth of 100 Megabits per second (Mbps) and an average web page size of 2 MegaBytes(MB). Converting the given bandwidth in Megabytes per second (MBps) from Megabits per second (Mbps), because the given web page size is in MegaBytes (MB). 100 Mbps (Megabits per second) = 100 / 8 = 12.5 MBps (Megabytes per second), Now to calculate the number of webpages that can be downloaded simultaneously, apply the following formula, Number of pages = Total Bandwidth available for the company / Average size of the web page, Hence the Number of pages = 12.5 MBps / 2 MB = 6.25 pages. As you know that the number of the web pages cannot be downloaded in fractions, hence the number of web pages should be rounded off to 6. The maximum number of web pages that can be downloaded simultaneously by utilizing the maximum bandwidth available to the company is 6. Hence, option A, 6 web pages is the correct web pages that can be downloaded.

Answer: A. 8 Million Emails can be stored on the server

Explanation: Given in the Question, we have a server having a storage capacity of 1 terabyte (TB). And we have to store emails on the server having an average size of 1 kilobyte (1 KB). In order to find the total number of emails that can be stored on the server, we have to first calculate the total space we can use to store the emails. Total storage capacity of the server = 1 terabyte (TB) = 1,000 gigabytes (GB) = 1,000,000 MegaByte (MB). Storage utilization is given as 80 % = 0.8. Hence, the usable storage capacity of the server = total storage capacity * storage utilization = 1,000,000 Megabytes (MB) * 0.8 = 800,000 Megabytes (MB). A number of emails that can be stored = total usable space on the server / average size of an email = 800, 000 Megabytes (MB) / 100 kilobyte (KB) = 800,000,000 Kilobytes (KB) / 100 kilobytes (KB) = 8,000,000 email pages = 8 million emails. Hence the email server can store approximately 8 million emails.

Answer: A. 200 sales per day

Explanation: Given in the Question, we have 10,000 unique visitors per day. But the conversion rate for these customers is only 2%. In order to calculate the expected sales on a particular day we have to multiply the number of unique customers with the conversion rate for the customers. Number of sales = Number of unique visitors on the web page * conversion rate for the total number of visitors = 10,000 * 2 % = 10,000 * 0.2 = 200 sales per day. Hence the total number of sales per day is 200 and option A is having the correct answer.
