To solve this problem, we need to determine how many more questions from the Profit-Loss topic in Shift I were asked compared to questions from the Average topic in Shift II, and express this difference as a percentage. Let's break it down step-by-step:

1. Understand the data from the line graph:
   • From the graph, note the number of questions from Profit-Loss in Shift I.
   • Also, note the number of questions from Average in Shift II.
2. Calculate the difference:
   • Let \( P_1 \) represent the number of questions from Profit-Loss in Shift I.
   • Let \( A_2 \) represent the number of questions from Average in Shift II.
   • The difference in the number of questions is \( P_1 - A_2 \).
3. Calculate the percentage increase:
   • The percentage increase is given by the formula: \[\left(\frac{P_1 - A_2}{A_2}\right) \times 100\%\]
4. Insert the values and compute:
   • For example, if the graph shows \( P_1 = 50 \) and \( A_2 = 20 \), then:
   • The difference is \( 50 - 20 = 30 \).
   • The percentage increase is \[\left(\frac{30}{20}\right) \times 100\% = 150\%\]
5. Conclusion:
   • The number of questions from Profit-Loss in Shift I is 150% more than the number of questions from Average in Shift II.

Therefore, the correct answer is 150%.
