To calculate the share of LCD monitors in total monitor sales, we first need to determine the number of LCD sales. Note that the total number of display sales is directly shown in the graph, but the number of LCD display sales needs to be calculated as the difference of total monitors and TFT monitors.
We get the following values:
\(Mon: \frac{10}{18}, Tue: \frac{10}{22}, Wed: \frac{12}{24}, Thu: \frac{10}{26}, Fri: \frac{12}{26}\).
Now we can compare the figures and see that all values, except of Wednesday's number are smaller than \(\frac{1}{2}\). Answer C it is.

LCD sales on each day = Mon-8. Tue-10 Wed-12 Thu-10 Fri-12
Ratio: Monday - 8/18
Tuesday - 10/22
Wednesday - 12/24
Thursday - 10/26
Friday - 12/26
Simplifying that Wednesday has the greatest ratio of LCD sales out of total sales
Ans C
