Gifted 4th Grade Math Challenge Problem: Yes or No Logic
作者: JC, 更新日期: 2013-02-23
Here is a challenge math problem for gifted students in their 4th grade. It is somewhat interesting as it relates more to logic/brain teaser than math. So could provide a good foundation for people interested in future careers such as computer science, financial data analysis etc.
On the planet Blam, two of the native words are tak and bin. One of them means "yes", the other "no". A visitor from our planet once asked a scholar of Blam whether tak meant "no". The scholar answered correctly, but although fluent in English, he absentmindedly replied in Blamese. Did the scholar answer tak or bin?
