Question 16
A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: C 🗳️ You can express the centered information as the algebraic form 2n+ 5 = 17. Now, solve for n: 2n= 12;n= 6. Find Quantity A: 3 less than is 3 - 3 = 0. Find Quantity B: 2 less than - is 2 - 2 = 0.

The quantities are equal;
The relationship cannot be determined from the information given.
Question 17
A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: B 🗳️ The comparison is easily made by substituting some simple numbers for p and q. For example, assume p= 1 and q= 2. The ratio of p to (p+ 1) is 1:2, or , while the ratio of q to (q+ 1) is 2:3, or . As long as 0 <p<q, the inequality will hold.
