2. What is the difference in the number of cities with the lowest temperature and highest temperature?

Correct Answer: Correct answer is: (C) 12.

Exam Relevance: CAT, GMAT, GRE, SAT

Difficulty: Moderate

Concept notes: In comparison-based data interpretation, the difference between the highest and lowest values is a common metric used to understand the range of data.

Common Mistakes: A common mistake is to misinterpret the question and calculate the difference between the highest and lowest values incorrectly, or to confuse the number of cities with the temperature values themselves.

Explanations: To find the difference in the number of cities with the lowest temperature and the highest temperature, we need to identify the number of cities with the lowest temperature and the number of cities with the highest temperature. The difference is then calculated by subtracting the smaller number from the larger number. According to the data, the number of cities with the lowest temperature is 36, and the number of cities with the highest temperature is 24. The difference is calculated as follows: \[ 36 - 24 = 12 \] Thus, the difference in the number of cities with the lowest temperature and the highest temperature is 12.
