In a line of six people, Ana is seated at one end while Ben is seated at the other end. Which of the following statements is correct about their positions?
Explanation: Since Ana is at one end and Ben is at the other, both are at the two extreme positions of the line. They cannot be in the middle or sitting together. Option B incorrectly places Ana in the middle, option C suggests only one person is between them which is wrong for ends, and option D states they are together in the middle which contradicts the given information.
If five friends—Sam, Rita, Tom, Alex, and Lily—are sitting in a row facing north, who is to the immediate left of Alex if the order is Sam, Rita, Alex, Tom, Lily from left to right?
Explanation: In this arrangement, since everyone is facing north, moving from left to right as given, Rita sits immediately before Alex. Tom is to Alex's right, while Sam is farther left and Lily is at the farthest right end. Thus, Rita is to Alex's immediate left.
In a line of eight seats, David is at position 2 from the left and John is at position 7 from the left. How many people sit between David and John?
Explanation: Positions 2 and 7 from the left have the numbers as 2 and 7. Subtracting 2 from 7 gives you 5, but because the positions themselves are not included, you must subtract one more, leaving 4 people in between. Option B is inaccurate as it counts the positions themselves, and options C and D are either too low or too high.
Six friends are sitting around a circular table. If Sara is seated immediately between Kevin and Tina, who are Sara's neighbors?
Explanation: Sara sitting immediately between Kevin and Tina means her neighbors are precisely Kevin and Tina. The other options either use names not given in the immediate neighbor scenario or incorrectly combine different people as Sara's neighbors.
If seven friends are seated in a circle facing the center, who is to the immediate right of Nina if she is between Tara and Meena?
Explanation: In a circular arrangement facing the center, the immediate right is clockwise. If Nina is between Tara and Meena, Meena sits on Nina’s right. Zara is not mentioned in the scenario, and Tara is on the other side, not on Nina’s right. Nina cannot be immediately to her own right.
Eight people are sitting in a circle facing the center. If Alice is sitting directly opposite Bob, how many people are seated between Alice and Bob?
Explanation: In a circle of eight, the person directly opposite will have three people on each side in between. The options for 4, 5, and 2 miscalculate the seating arrangement, as 4 would indicate nine people, while 5 and 2 correspond to additional or fewer seats, respectively.
Six people sit in a row facing north. If only the first and last people turn to face south, who is sitting in an opposite direction to the others?
Explanation: Only the persons at the ends are facing south; the rest are facing north, meaning only those two are in an opposite direction. Option B suggests everyone turned, which is incorrect. Option C focuses on the middle ones, incorrectly, and D ignores the scenario given.
How many different seating arrangements are possible for four people sitting in a straight line?
Explanation: For four people, the number of arrangements is calculated as 4 factorial (4!), which equals 24. The other options result from incorrect calculations such as 4 squared or using addition instead of multiplication, thus they are incorrect.
How many different ways can five people be arranged around a circular table?
Explanation: In circular arrangements, the formula is (n-1)! for n people; for 5 people, (5-1)! = 24. Option B, 120, is the number for a linear arrangement (5!), and the options 60 and 12 result from incorrect divisors or multipliers.
In a row of seven students—Mike, Lucy, Zoe, Ryan, Steve, Nina, and Paul—who is seated in the middle position if arranged as Mike, Lucy, Zoe, Ryan, Steve, Nina, Paul from left to right?
Explanation: With seven students, the fourth position is the middle. Counting from the left, Ryan is fourth. Nina is sixth, Lucy is second, and Zoe is third, all not the middle position.
In a row of six, if Lisa must sit directly next to Mark, and there are no special restrictions otherwise, how many such pairs of adjacent Lisa-Mark arrangements are possible?
Explanation: To calculate this, consider Lisa-Mark as a unit, so there are 5 possible spots for the pair in 6 seats, and for each, the pair can sit as Lisa-Mark or Mark-Lisa (2 ways). That is 5 x 2 = 10. Options B, C, and D are incorrect due to miscalculations.
If five persons are seated in this order from left to right: Jay, Kim, Mia, Roy, Sue, who is seated third from the left?
Explanation: Counting from the left, Mia is in the third position. The other choices reflect different seating positions; Jay is first, Roy is fourth, and Sue is fifth from the left.
Eight players are seated equally around a circular table. Who is seated third to the right of Judy if all are facing the center?
Explanation: In a circular arrangement facing center, the right direction is clockwise. The third person after Judy when counting clockwise is correct. The first option is only the immediate neighbor, not the third, and the second is an incorrect direction. Judy herself cannot be her own third right.
If four friends are sitting in a line and Anna must always sit at either of the two ends, how many possible seating arrangements exist?
Explanation: Anna can occupy either end (2 choices), and the remaining three friends can be arranged in 3! = 6 ways. Thus, 2 x 6 = 12. Options B and D result from partial or incomplete multiplication, and C is an overestimation.
Seven people sit in a row. If Tom must sit at the left-most end and Martha must sit at the right-most end, how many unique arrangements are possible?
Explanation: With 2 positions fixed, the remaining five people can be arranged in 5! = 120 ways. Option B (720) is for all seven people, C (24) is for four, and D (360) incorrectly uses 6! or mixes calculations.
If four boys and four girls are to be seated alternately in a circular arrangement, how many such possible arrangements are there?
Explanation: In a circle, fix one boy, arrange remaining 3 boys (3!), then 4 girls (4!), so 3! x 4! = 6 x 24 = 144; then multiply by 2 as boys and girls can alternate starting with either. 144 x 2 = 288, but actual alternation for eight (and not fixing a point) gives 4! x 4! = 576, multiplied by 2 for each gender first: 1152. Other options are miscalculations.
