Hi Awash,
Great question.
Whenever possible on local questions, I try to draw out a mini-diagram. For this one, we know that R is in first, which puts T in 7th. It looks like there's a large open section in the middle, but we can think about where we see limitations. The first place I would look is at where the h/s block could go. Either it's going to go in 2/5 or 3/6. Which could look like this:
Scenario 1: R S P L H M T
or
Scenario 2: R L H M P S T
or
Scenario 3: R _ S _ _ H T
With those three in mind, we can look at the answers.
Answer choice (A): The third sale is H. In all three, I know where H is. If I know H is in 3, I can fill out the rest of scenario 2 above. This is the correct answer.
Answer choice (B): The third sale is S. In the final situation, S is third, but we don't know where several variables go. This cannot be the correct answer.
Answer choice (C): The fourth sale is L. In the final situation, L can be 4th and in the first situation L is in 4th. It could be either situation. This can't be the right answer.
Answer choice (D): The fourth sale is on M. This could occur in either scenario 2 or 3 above. Since we don't know which it cannot be the right answer.
Answer choice (E): The sixth sale is on H. This is only in the final scenario, but there are still blank spaces. I don't know how those must be filled, so this is not the correct answer.
Hope that helps!
Rachael
