In class, the students were correcting their maths questions…
Question: A school bus is allowed to carry only 40 pupils. How many buses are needed to take all 220 pupils to the zoo? The correct answer was 6 buses.
Ms Ng told the students that the answer 5 buses was wrong, because the remaining 20 pupils would not have any transport to get to the zoo.
One of the student, raised his hand and said, “Ms Ng, you are wrong. You see, the question said that the bus is allowed to carry ONLY 40 pupils. Not any other number BUT 40!”
Ms Ng was stumped but tried to reason with him, “Then what would happen to the remaining 20 if you cannot hire a bus for them?”
The student said, “Too bad, they have to walk to the zoo. If not, the School has to hire taxis to take them.”
