Example Question #64 : Two Variable
A chef is arranging spices on a shelf. Four of the spices are in large jars: garlic, oregano, pepper, and salt. Three of the spices are in small jars: basil, cumin, and mint. The following conditions apply:
A large jar must be first or fourth
Pepper must come after cumin but before basil
The jar of salt must be the first large jar in the line
Basil cannot be immediately before or after garlic
Which of the following could be first?
mint
pepper
oregano
basil
garlic
mint
Mint could be first but the other options all must come at some point after salt.
Example Question #65 : Two Variable
A chef is arranging spices on a shelf. Four of the spices are in large jars: garlic, oregano, pepper, and salt. Three of the spices are in small jars: basil, cumin, and mint. The following conditions apply:
A large jar must be first or fourth
Pepper must come after cumin but before basil
The jar of salt must be the first large jar in the line
Basil cannot be immediately before or after garlic
When pepper is third, which of the following could be true?
mint is second
oregano is fifth
oregano is second
garlic is second
cumin is fifth
oregano is fifth
When pepper is third, salt and cumin are the only spices to come before it. As a result, oregano, garlic, and mint cannot be second. Further, cumin must come before pepper and, therefore, cannot be fifth. Oregano could be fifth.
Example Question #333 : Lsat Logic Games
Eight students – Alice, Ben, Carl, Daisy, Earl, Frank, Gretchen, and Hailey – are sitting at the front of a school bus in four seats, with one student sitting on the right side and one student on the left side of each seat. The seats are numbered sequentially 1 through 4, with Seat 1 at the front of the bus and Seats 2, 3, and 4 immediately behind, in that order. The following conditions apply to the seating arrangement:
Ben must sit on the right side of whatever seat he sits in.
Frank and Gretchen sit closer to the front of the bus than Daisy.
Carl and Daisy do not sit in the same seat.
Earl and Hailey sit exactly one seat apart from each other, and on the same side of the seat.
If Carl and Hailey sit in the same seat, Frank and Ben also sit in the same seat.
Which one of the following could be a complete and accurate matching of students to their seats?
Seat 1: Earl, left side, Frank, right side; Seat 2: Hailey, left side, Gretchen, right side; Seat 3: Alice, left side, Ben, right side; Seat 4: Daisy, left side, Carl, right side
Seat 1: Alice, left side, Hailey, right side; Seat 2: Frank, left side, Earl, right side; Seat 3: Gretchen, left side, Daisy, right side; Seat 4: Carl, left side, Ben, right side
Seat 1: Carl, left side, Earl, right side; Seat 2: Frank, left side, Hailey, right side; Seat 3: Gretchen, left side, Ben, right side; Seat 4: Alice, left side, Daisy, right side
Seat 1: Frank, left side, Alice, right side; Seat 2: Carl, left side, Hailey, right side; Seat 3: Gretchen, left side, Earl, right side; Seat 4: Daisy, left side, Ben, right side
Seat 1: Alice, left side, Ben, right side; Seat 2: Carl, left side, Earl, right side; Seat 3: Frank, left side, Gretchen, right side; Seat 4: Daisy, left side, Hailey, right side
Seat 1: Carl, left side, Earl, right side; Seat 2: Frank, left side, Hailey, right side; Seat 3: Gretchen, left side, Ben, right side; Seat 4: Alice, left side, Daisy, right side
The correct answer choice is the only one that does not violate the listed conditions. Each of the incorrect answer choices either has Daisy not sitting behind Frank and Gretchen, has Carl and Daisy sitting in the same seat, has Earl and Hailey not sitting one seat from each other, or failing to have Frank and Ben sit together when Carl and Hailey are sitting together.
Example Question #334 : Lsat Logic Games
Eight students – Alice, Ben, Carl, Daisy, Earl, Frank, Gretchen, and Hailey – are sitting at the front of a school bus in four seats, with one student sitting on the right side and one student on the left side of each seat. The seats are numbered sequentially 1 through 4, with Seat 1 at the front of the bus and Seats 2, 3, and 4 immediately behind, in that order. The following conditions apply to the seating arrangement:
Ben must sit on the right side of whatever seat he sits in.
Frank and Gretchen sit closer to the front of the bus than Daisy.
Carl and Daisy do not sit in the same seat.
Earl and Hailey sit exactly one seat apart from each other, and on the same side of the seat.
If Carl and Hailey sit in the same seat, Frank and Ben also sit in the same seat.
If Daisy sits in Seat 2 on the right side of the seat, which one of the following must be true?
Gretchen sits on the right side of her seat.
Hailey sits in Seat 2.
Alice sits on the left side of her seat.
Ben sits in Seat 4.
Earl sits on the left side of his seat.
Earl sits on the left side of his seat.
With Daisy sitting in Seat 2, Frank and Gretchen must both sit in Seat 1 to be closer to the front than Daisy. This means there is no room for Earl or Hailey (who must sit on the same side) to sit on the right side of their seats, because Ben must also sit on the right side of his seat. The remaining answer choices could be true, but do not have to be.
Example Question #66 : Two Variable
Eight students – Alice, Ben, Carl, Daisy, Earl, Frank, Gretchen, and Hailey – are sitting at the front of a school bus in four seats, with one student sitting on the right side and one student on the left side of each seat. The seats are numbered sequentially 1 through 4, with Seat 1 at the front of the bus and Seats 2, 3, and 4 immediately behind, in that order. The following conditions apply to the seating arrangement:
Ben must sit on the right side of whatever seat he sits in.
Frank and Gretchen sit closer to the front of the bus than Daisy.
Carl and Daisy do not sit in the same seat.
Earl and Hailey sit exactly one seat apart from each other, and on the same side of the seat.
If Carl and Hailey sit in the same seat, Frank and Ben also sit in the same seat.
If Carl and Ben sit in Seat 2, then each of the following could be true EXCEPT
Frank and Gretchen sit in Seat 1.
Gretchen and Alice sit in Seat 1.
Frank and Hailey sit in Seat 3.
Daisy and Earl sit in Seat 3.
Alice and Frank sit in Seat 3.
Alice and Frank sit in Seat 3.
With Carl and Ben in Seat 2, either Earl or Hailey must sit in Seat 3, and whoever of the two does not sit in Seat 3 must sit in Seat 4. Otherwise, there is no way they can sit one seat away from each other, since Carl and Ben occupy Seat 2. Thus, Alice and Frank cannot sit in Seat 3. The remaining answer choices could be true.
Example Question #336 : Lsat Logic Games
Eight students – Alice, Ben, Carl, Daisy, Earl, Frank, Gretchen, and Hailey – are sitting at the front of a school bus in four seats, with one student sitting on the right side and one student on the left side of each seat. The seats are numbered sequentially 1 through 4, with Seat 1 at the front of the bus and Seats 2, 3, and 4 immediately behind, in that order. The following conditions apply to the seating arrangement:
Ben must sit on the right side of whatever seat he sits in.
Frank and Gretchen sit closer to the front of the bus than Daisy.
Carl and Daisy do not sit in the same seat.
Earl and Hailey sit exactly one seat apart from each other, and on the same side of the seat.
If Carl and Hailey sit in the same seat, Frank and Ben also sit in the same seat.
If Gretchen sits exactly two seats apart from Frank, which one of the following must be true?
Hailey sits closer to the front of the bus than Daisy.
Ben sits closer to the front of the bus than Earl.
Alice sits closer to the front of the bus than Hailey.
Carl sits closer to the front of the bus than Daisy.
Gretchen sits closer to the front of the bus than Carl.
Carl sits closer to the front of the bus than Daisy.
Since Gretchen and Frank must both sit closer to the front of the bus than Daisy, under this scenario Daisy must sit in Seat 4 (with Gretchen or Frank in Seat 1, and the other in Seat 3). Since Carl cannot sit next to Daisy, he cannot sit in Seat 4. Thus, he must sit closer to the front of the bus than Daisy. The remaining answer choices, while they could be true, do not have to be.
Example Question #337 : Lsat Logic Games
Eight students – Alice, Ben, Carl, Daisy, Earl, Frank, Gretchen, and Hailey – are sitting at the front of a school bus in four seats, with one student sitting on the right side and one student on the left side of each seat. The seats are numbered sequentially 1 through 4, with Seat 1 at the front of the bus and Seats 2, 3, and 4 immediately behind, in that order. The following conditions apply to the seating arrangement:
Ben must sit on the right side of whatever seat he sits in.
Frank and Gretchen sit closer to the front of the bus than Daisy.
Carl and Daisy do not sit in the same seat.
Earl and Hailey sit exactly one seat apart from each other, and on the same side of the seat.
If Carl and Hailey sit in the same seat, Frank and Ben also sit in the same seat.
If Carl sits in the same seat as Frank, exactly how many different students could sit in Seat 4?
eight
six
four
seven
five
five
This question is simpler than it appears. Under normal circumstances, the only students who cannot sit in Seat 4 are Frank and Gretchen (since they must always sit in front of Daisy). With Carl and Frank sitting in the same seat, Carl obviously cannot sit in Seat 4 either. However, any of the remaining five students could sit in Seat 4 under these circumstances, if properly arranged.
Example Question #71 : Two Variable
Eight students – Alice, Ben, Carl, Daisy, Earl, Frank, Gretchen, and Hailey – are sitting at the front of a school bus in four seats, with one student sitting on the right side and one student on the left side of each seat. The seats are numbered sequentially 1 through 4, with Seat 1 at the front of the bus and Seats 2, 3, and 4 immediately behind, in that order. The following conditions apply to the seating arrangement:
Ben must sit on the right side of whatever seat he sits in.
Frank and Gretchen sit closer to the front of the bus than Daisy.
Carl and Daisy do not sit in the same seat.
Earl and Hailey sit exactly one seat apart from each other, and on the same side of the seat.
If Carl and Hailey sit in the same seat, Frank and Ben also sit in the same seat.
If Hailey sits in Seat 1 on the right side of the seat, which one of the following could be true?
Ben and Earl sit in the same seat.
Daisy and Earl sit in the same seat.
Daisy and Hailey sit in the same seat.
Carl and Hailey sit in the same seat.
Alice and Ben sit in the same seat.
Carl and Hailey sit in the same seat.
Carl and Hailey can sit in the same seat in this scenario. With Hailey sitting on the right side of Seat 1, Earl must sit in seat 2 (on the right side). Further, since Carl and Hailey are sitting together, Ben and Frank must sit together, and it must be in Seat 3. This means Daisy must sit in Seat 4 with Alice, and Gretchen can take the remaining spot in Seat 2. The remaining answer choices violate one or more conditions under these circumstances.
Example Question #331 : Lsat Logic Games
A consultant has agreed to see each of his nine clients-- L, M, N, O, P, Q, R, S, T-- once in the next six days, from Monday through Saturday. He arranges his schedule so that he can see at least one of his clients each day, while maintaining the following conditions:
O is always scheduled on a day before R and M.
P is not scheduled for Saturday.
If T is scheduled on a day after O, then S is scheduled on a day after N.
If T is scheduled on a day before O, then R is scheduled on a day before L.
The consultant always sees fewer clients on Friday and Saturday combined than he sees on any other two days of the week combined.
If the consultant sees O on Wednesday, what is the maximum number of clients that he can see after Wednesday?
3
4
2
1
5
4
The correct answer is 4 clients. Placing O on Wednesday does not lead to any particularly unique diagrams. This game is fairly loose-- there are a lot of possible diagrams. The key insight here is the fact that Friday and Saturday can accommodate, at most, two clients total and any other day accommodates at most two.
Here is a possible diagram that maximizes clients after Wednesday:
Mon: T
Tues: Q, P
Wed: S, O
Thurs: R, N
Fri: M
Sat: L
Example Question #331 : Lsat Logic Games
A gym teacher wants his 6 students to line up in height order, from shortest to tallest. Corrin and Theresa are girls. Ben, Jonathan, Will, and Dan are the boys.
- Will is neither the tallest nor the shortest
- No girl is taller than Jonathan
- Dan is shorter than Corrin, but taller than Theresa
- Ben is the tallest
If Jonathan is the 2nd tallest, what must be true?
Will is 4th tallest.
Dan is the 2nd tallest.
Corrin is not the shortest or second shortest.
Will is 2nd shortest.
Will is 5th tallest.
Corrin is not the shortest or second shortest.
If Jonathan is 2nd tallest, that means Will can go anywhere but 6th, 2nd or 1st tallest positions. Since Corrin is taller than Dan, and Theresa is shorter than Dan, each of their positions can be altered by Will. Thus, the only certainty, is that Corrin cannot be the first or second in line, because Theresa and Dan must precede her.
