• Question 2 of 5 2. Question Five people P, Q, R, S, T are sitting on a bench. P is sitting next to Q, and S is sitting next to T. Now consider the following statements and the question: Statement I: T is not sitting with P, and T is at the right end. Statement II: Q is to the immediate left of R, and R is not next to S. Statement III: P and S are not sitting together. Question: What is the position of Q? How many of the given statements are required to answer the question? (a) Only one (b) Only two (c) All three (d) None of the above Correct Answer: (b) Solution: Given base conditions: P is next to Q S is next to T Use Statement II: Q is to the immediate left of R → Q R R not next to S → so Q R cannot be beside S T block. This eliminates many possibilities but still leaves two patterns: _ Q R _ S T S T _ Q R Still insufficient. Now use Statement I: T is at the right end, and not with P. So S T must be at the right end: Since R cannot be next to S (from Statement II), Q R cannot be placed at positions 3 and 4. So Q R must be at positions 1 and 2: Since P is next to Q (given), P must be in the 3rd position: Final arrangement: Thus, Q is in position 1. Statements I and II are required; III is not needed. Correct answer: (b) Incorrect Answer: (b) Solution: Given base conditions: P is next to Q S is next to T Use Statement II: Q is to the immediate left of R → Q R R not next to S → so Q R cannot be beside S T block. This eliminates many possibilities but still leaves two patterns: _ Q R _ S T S T _ Q R Still insufficient. Now use Statement I: T is at the right end, and not with P. So S T must be at the right end: Since R cannot be next to S (from Statement II), Q R cannot be placed at positions 3 and 4. So Q R must be at positions 1 and 2: Since P is next to Q (given), P must be in the 3rd position: Final arrangement: Thus, Q is in position 1. Statements I and II are required; III is not needed. Correct answer: (b)
#### 2. Question
Five people P, Q, R, S, T are sitting on a bench. P is sitting next to Q, and S is sitting next to T.
Now consider the following statements and the question:
Statement I: T is not sitting with P, and T is at the right end. Statement II: Q is to the immediate left of R, and R is not next to S. Statement III: P and S are not sitting together.
Question: What is the position of Q?
How many of the given statements are required to answer the question?
• (a) Only one
• (b) Only two
• (c) All three
• (d) None of the above
Answer: (b)
Solution:
Given base conditions:
• P is next to Q
• S is next to T
Use Statement II:
Q is to the immediate left of R → Q R R not next to S → so Q R cannot be beside S T block.
This eliminates many possibilities but still leaves two patterns:
• _ Q R _ S T
Still insufficient.
Now use Statement I:
T is at the right end, and not with P. So S T must be at the right end:
Since R cannot be next to S (from Statement II), Q R cannot be placed at positions 3 and 4.
So Q R must be at positions 1 and 2:
Since P is next to Q (given), P must be in the 3rd position:
Final arrangement:
Thus, Q is in position 1.
Statements I and II are required; III is not needed.
Correct answer: (b)
Answer: (b)
Solution:
Given base conditions:
• P is next to Q
• S is next to T
Use Statement II:
Q is to the immediate left of R → Q R R not next to S → so Q R cannot be beside S T block.
This eliminates many possibilities but still leaves two patterns:
• _ Q R _ S T
Still insufficient.
Now use Statement I:
T is at the right end, and not with P. So S T must be at the right end:
Since R cannot be next to S (from Statement II), Q R cannot be placed at positions 3 and 4.
So Q R must be at positions 1 and 2:
Since P is next to Q (given), P must be in the 3rd position:
Final arrangement:
Thus, Q is in position 1.
Statements I and II are required; III is not needed.
Correct answer: (b)
• Question 3 of 5 3. Question When 60% of a number x is added to another number y, the sum becomes 130% of the value of y. When 30% of the number x is added to another number z, the sum becomes 120% of the value of z. Which one of the following is correct? a) x > y > z b) y > z > x c) z > y > x d) y > x > z Correct Answer: (b) Solution From the first sentence: 60% of x + y = 130% of y That is, 0.6x + y = 1.3y 0.6x = 1.3y − y = 0.3y x = (0.3/0.6) y = 0.5y So, x = 0.5y ⇒ y = 2x Thus, y > x From the second sentence: 30% of x + z = 120% of z 0.3x + z = 1.2z 0.3x = 1.2z − z = 0.2z x = (0.2/0.3)z = (2/3)z So, x = (2/3)z ⇒ z = (3/2)x = 1.5x Thus, z > x Now compare y and z using x: We have: y = 2x z = 1.5x So, y > z > x Therefore, the correct order is y > z > x. Hence, the correct option is (b). Incorrect Answer: (b) Solution From the first sentence: 60% of x + y = 130% of y That is, 0.6x + y = 1.3y 0.6x = 1.3y − y = 0.3y x = (0.3/0.6) y = 0.5y So, x = 0.5y ⇒ y = 2x Thus, y > x From the second sentence: 30% of x + z = 120% of z 0.3x + z = 1.2z 0.3x = 1.2z − z = 0.2z x = (0.2/0.3)z = (2/3)z So, x = (2/3)z ⇒ z = (3/2)x = 1.5x Thus, z > x Now compare y and z using x: We have: y = 2x z = 1.5x So, y > z > x Therefore, the correct order is y > z > x. Hence, the correct option is (b).
#### 3. Question
When 60% of a number x is added to another number y, the sum becomes 130% of the value of y. When 30% of the number x is added to another number z, the sum becomes 120% of the value of z. Which one of the following is correct?
• a) x > y > z
• b) y > z > x
• c) z > y > x
• d) y > x > z
Answer: (b)
Solution
From the first sentence: 60% of x + y = 130% of y
That is, 0.6x + y = 1.3y 0.6x = 1.3y − y = 0.3y x = (0.3/0.6) y = 0.5y
So, x = 0.5y ⇒ y = 2x Thus, y > x
From the second sentence: 30% of x + z = 120% of z
0.3x + z = 1.2z 0.3x = 1.2z − z = 0.2z x = (0.2/0.3)z = (2/3)z
So, x = (2/3)z ⇒ z = (3/2)x = 1.5x Thus, z > x
Now compare y and z using x:
We have: y = 2x z = 1.5x
So, y > z > x
Therefore, the correct order is y > z > x.
Hence, the correct option is (b).
Answer: (b)
Solution
From the first sentence: 60% of x + y = 130% of y
That is, 0.6x + y = 1.3y 0.6x = 1.3y − y = 0.3y x = (0.3/0.6) y = 0.5y
So, x = 0.5y ⇒ y = 2x Thus, y > x
From the second sentence: 30% of x + z = 120% of z
0.3x + z = 1.2z 0.3x = 1.2z − z = 0.2z x = (0.2/0.3)z = (2/3)z
So, x = (2/3)z ⇒ z = (3/2)x = 1.5x Thus, z > x
Now compare y and z using x:
We have: y = 2x z = 1.5x
So, y > z > x
Therefore, the correct order is y > z > x.
Hence, the correct option is (b).
