SolutionWhen comparing these quantities, it is important to remember that a nonzero number and its negative have the same absolute value. For example, ⎪−2⎪=⎪2⎪=2. Keeping this in mind, you can see that the positive integers 2, 3, 4, and 5 and the negative integers −2, −3, −4, and −5 all satisfy the inequalities 2 ≤ ⎪n⎪ ≤ 5, and that these are the only such integers. Thus, the set X consists of the integers −5, −4, −3, −2, 2, 3, 4, and 5. The greatest of these integers is 5, and its absolute value is 5. The least of these integers is −5, and its absolute value is also 5. Therefore, Quantity A is equal to Quantity B. The correct answer is Choice C.

We're told that n is an INTEGER Given: 2 ≤ n ≤ 5 First recognize that n = 2, n = 3, n = 4 and n = 5 all satisfy the given inequality. Next notice that some NEGATIVE values work too. For example, 2 = 2, so it's true that 2 ≤ 2 ≤ 5. So, x = 2 is a possible solution Likewise, 3 = 3, so it's true that 2 ≤ 3 ≤ 5. So, x = 3 is a possible solution And 4 = 4, so it's true that 2 ≤ 4 ≤ 5. So, x = 4 is a possible solution And 5 = 5, so it's true that 2 ≤ 5 ≤ 5. So, x = 5 is a possible solution Set X = { 5, 4, 3, 2, 2, 3, 4, 5} Quantity A: The absolute value of the greatest integer in X Quantity B: The absolute value of the least integer in X The GREATEST integer = 5The LEAST integer = 5So, we get: Quantity A:  5 Quantity B:  5 Evaluate to get: Quantity A: 5 Quantity B: 5 Answer: Cheers, Brent

It do not require any sort of calculations. Just mental work Set x = {5, 4, 3, 2, 2, 3, 4, 5} Now, absolute value of greatest and least is same i.e 5. Thus, choice C correct.

@sandy
I need a little understanding. If we take the values seperately e.g the equation can also be translated to n≤5 & 2≤n then n≤5 or 5≤n & n≤2 or 2≤n If we look at the underline set of values, it shows thaat n can be anything greater then/equal to 5 and lesser than/equal to 2. I got answer d. Can you please tell me what i am doing wrong? Thanks!!

Practice Questions Question: 7 Page:331 Difficulty: easy \(2 \leq n \leq 5.\)... so n can be 2, 3, 4, 5.. so n = 5, 4, 3, 2, 2, 3, 4, 5 thus the greatest integer will be 5 and 5 = 5 and the smallest integer will be 5 and 5=5 thus both are equal C
