The Jahlberg Factory subdivided its workforce into teams and initiated a competition among the teams to increase work production. The graph above is a pie chart representing the percentages of total units produced by each team during the four-week competition. Team Ginseng's original team (Division A) was disbanded and re-formed with different workers (Division B) partway into the competition period, with no lapse in work.
Use the drop-down menus to fill in the blanks in each of the following statements based on the information given by the graph.
1. The ratio of the percentage produced by the lowest-producing team to the percentage produced by the next-highest producing team was .
2. If Team Ginseng was re-formed 2.5 weeks into the competition, then Division B's rate of units produced per week was approximately of Division A's rate.

Official Explanation
The ratio of the percentage produced by the lowest-producing team to the percentage produced by the next-highest producing team was__________.
This question asks for the ratio of the percentage produced by the lowest-producing team to the percentage produced by the next-highest producing team. The lowest-producing team was Team Faylur, with 12% of the total units, and the next-highest producing team (after Team Faylur) was Team Ruiz, with 14% of the total units. Thus the ratio of the percentage produced by Team Faylur (12%) to the percentage produced by Team Ruiz (14%) is 12 to 14 or 6 to 7.
Answer: B
If Team Ginseng was re-formed 2.5 weeks into the competition, then Division B's rate of units produced per week was approximately___________of Division A's rate.
According to the chart, Team Ginseng produced 25% of the total units. Of the units produced by Team Ginseng, 42% were produced by Team A. Thus, the units produced by Division A represent 42% of 25% of the total, or 10.5% of the total. Since the units produced by Team Ginseng come only from Division A and Division B, you can calculate percentage of units produced by Division B: Team Ginseng - Division A = Division B, or 25% - 10.5% = 14.5%. Thus, Division B produced 14.5% of the total.
If Team Ginseng was re-formed 2.5 weeks into the competition, then Division A worked for 2.5 weeks and produced 10.5% of the total units, while Division B worked for 1.5 weeks and produced 14.5% of the total units. Plugging In 1000 for total units and using a Rate Pie may help to clarify this problem:
Division A's rate was 42 units per week while Division B's rate was 96.67 units per week. Since the question asks "Division B's rate of units produced per week was approximately _____of Division A's rate,” you should first try to ballpark. Division B's rate is more than double Division A's rate, so the percentage difference will be more than 200%. Since only one answer choice is higher than 200%, you can confidently choose it without doing the calculations. However, if you did wish to do the calculations, set this up using percent translation:
Division B's rate was what percent of Division A's rate:
\(96.67 = \frac{x}{100}*42\)
Now simplify: \(9667 = 42x so x= \frac{9667}{42} =230.16\)
Answer: E

General Discussion
Q1) The ratio of the percentage produced by the lowest-producing team to the percentage produced by the next-highest producing team was__________.
A1) Percentage produced by the lowest-producing team (Faylur) = 12%
and, Percentage produced by the next-highest producing team (Ruiz) = 14%
Hence, \(Ratio =\frac{ 12}{14}\) =>\( \frac{6}{7}\)
Hence Option B is the answer!
Q2) If Team Ginseng was re-formed 2.5 weeks into the competition, then Division B's rate of units produced per week was approximately___________of Division A's rate.
A2) As we need to finally find the answer in % only, let's assume the total units produced as 10,000.
So, Team Ginseng produced 25% of 10,000 = 2,500 units in 4 weeks.
And Div A produced (in 2.5 weeks) produced 42% of 2500 units = 1,050
While, Div B produced (in 1.5 weeks) produced 58% of 2500 units = 1,450
Rate of units per week for Div A =\( \frac{1175}{2.5} = 420\)
While, Rate of units per week for Div B = \( \frac{1325}{1.5} = 966.67\)
Here, we observe that Div B's rate is more than double the rate of Div A. Answer should be Option E.
For info, \(\frac{966.67}{420} = 2.30\)
