LSAT 84, Logic Game 4, Question 19, LSATHacks

In this question, L and V can’t have 5 year bonds. Since every corporation needs at least one bond, that means they both have 10 year bonds. You should draw that, and combine it with the existing rules:

There are a few things to note here:

• H has 5, because H and L can’t be the same (rule 1)
• R has 10, because of rule 3 (L10 —> R10)
• H, L and V all have vertical lines to their right indicating that they are closed and can take no more bonds

In the setup, I said this was a counting game. So, let’s count what we’ve placed: 5, 10, 10, 10. That means the bonds left are 5, 5, 5, 10.

There are three 5’s, and only three open groups: G, R and S. That means they all must have a 5:

Either G or S could have the final ten. But since this is a must be true, we should look for something definite. The right answer could be any of: G must have 5, S must have 5, R must have 5 and 10.

B is CORRECT. R has to have both. A, C and D could be true, but don’t have to be. E has to be false.
