One of the students immediately exclaimed in horror, “Isn’t that family too stingy? Two people have to share a bowl of rice? How in the world do they eat like that?”

Yang Wei’s face darkened. “Why are you picking faults with the question? We’re here to answer the question, not to gossip about whether the family is stingy or not.”

Zu An chuckled softly under his breath. He couldn’t understand why Yang Wei would think that such a simple question was somehow difficult. Could it be that people in this world didn’t understand the concept of algebra?

Zu An did a rough calculation before writing down ‘60’.

“Gulp~”

Yang Wei swallowed in shock. How could this be? Did the fellow see the answer key beforehand? No, that’s impossible. I came up with these questions on the spot! Are these questions actually that easy?

He started to doubt his sanity, but was comforted by the confused looks on the faces of the students all around. Nay, how can that be? That fellow must have guessed the answer to the question, and happened to get ‘60’ on his first try. Yes, that’s definitely the case.

Zu An moved on to the third question.

‘In Brightmoon City’s market, a rooster is worth 5 qian, a chicken is worth 3 qian, and three chicks are worth 1 qian. The farmer used a total of 100 qian to buy 100 animals. So, how many roosters, chicken, and chicks did she buy in total?’[1]

Hm? This question looks pretty...
