Tricky Questions
The tricky questions and answers in this lesson will help you understand the types of tricky questions you can expect in data science interviews.
A census in New York found that about 50% of households consisted of just one person. A TV channel reported this: "Half the residents of New York live alone." Do you agree?
No, as they wrongly interpreted census results. Census results found that 50% of households consist of just one person, meaning among 100% of households, 50% contain a single person.
Considering the remaining 50% of households, where each of these households would have more than one person, the number of residents living in this remaining 50% of households is higher than the number of residents in those households consisting of just one person. Therefore, it can't be possible for half of New York residents to live alone.
If four items of clothing can dry in four hours, how many hours will be required to dry eight?
If four items of clothing can dry in four hours, then eight will also dry in four hours because the dryness of clothes does not depend on the number of items. It depends on the time, and it will be the same for any value.
What is the largest four-digit number that will be divisible by 4,444?
The largest four-digit number that will be divisible by 4,444 is 8,888 because 4,444 is itself a four-digit number, and any number greater than 8,888 and less than 10,000 cannot be perfectly divisible by 4,444.
