บท 109: Professor He’s Question Paper - 2

As Qian Wenrui scanned Fu Zhi's question paper, she saw the solution coming. 

Although she would not normally solve the problem like Fu Zhi had, Fu Zhi had written comments on her answer sheet. 

Her steps were simple, and her thought process was clear. Qian Wenrui was even more amazed when she saw how Fu Zhi had gotten the number 15 on the second question through reverse thinking.

She read through her answers again, yet she still could not wrap her mind around her steps.

Below the podium, Lu Chuwan raised her hand. "Ms. Qian."

Qian Wenrui's heart skipped a beat, and she put Fu Zhi's answer sheet in a sealed bag. She then approached Lu Chuwan and asked, "What's wrong?" 

"The data given for the second question is incomplete. Could Professor He have made a mistake?" 

Lu Chuwan was standing very close to Qian Wenrui, and they pitched their voices low as they whispered into each other's ears.
