ExplanationIn Quantity A, if y = 4, then the numbers (arranged in increasing order) become \(x, x_{2}, x_{3}, x_{4}, x_{4}, x_{6}\); the mode is \(x_{2}\). In Quantity B, if y = 5, then the numbers become \(x, x_{2}, x_{4}, x_{4}, x_{5}, x_{6}\). Usually, you’d need to take the average of the middle two numbers to find the median because there is an even number of values, but in this case they’re both \(x_{4}\). The median, then, is \(x_{4}\), so the quantities are equal. Because x > 1, you don’t have to worry about special cases such as 0, 1, negatives, or fractions, and the correct answer is choice (C).

How do you know that x > 1. And what does the subscript mean?
