Question 1

Given: P ≥ Q, Q > R, R ≤ S, S < T, T ≥ U. Which conclusion is DEFINITELY FALSE?

Accepted Answer

From P ≥ Q > R ≤ S < T ≥ U, we know: P > R (definite), Q > R (definite), S < T (definite), but relationships between P and T, Q and S, or R and U are indeterminate. The statement 'R > S' contradicts R ≤ S, making it definitely false.

Question 2

Given: P ≤ Q, Q < R, R ≥ S, S > T, T ≤ U. Which conclusion is DEFINITELY FALSE?

Accepted Answer

From the given: P ≤ Q < R ≥ S > T ≤ U. Let's check each option: (a) P < R: P ≤ Q < R, so P < R is TRUE. (b) S ≥ T: We have S > T, so S ≥ T is TRUE. (c) T > U: We have T ≤ U, which means T is less than or equal to U, so T > U is FALSE. (d) Q ≤ R: We have Q < R, so Q ≤ R is TRUE.

Question 3

A transformation rule for numbers is:
Step 1: Add 10 to the input
Step 2: Multiply the result by 2
Step 3: Subtract the original input

If the input is 6, what is the final output?

Accepted Answer

Input = 6. Step 1: 6+10 = 16. Step 2: 16×2 = 32. Step 3: 32-6 = 26. Final output is 26.

Question 4

Given: A > B, B ≥ C, C > D, D = E, E < F. Which of the following conclusions is definitely TRUE?

Accepted Answer

From the given inequalities: A > B ≥ C > D = E < F. We can deduce A > C (transitive), A > D (transitive), B > D (transitive), and D = E. However, we cannot determine the relationship between A and F, or between C and F, because F's position relative to the chain is only constrained by E < F, and E is the smallest in the A-B-C-D-E chain.

Question 5

Given: X ≥ Y, Y > Z, Z ≥ W, W < V, V ≤ X. Which conclusion is DEFINITELY TRUE?

Accepted Answer

From X ≥ Y > Z ≥ W < V ≤ X: We can establish X > Z (transitive), Y > W (transitive), X > W (transitive), and V ≤ X. The relationship between V and Y, V and Z, or V and W cannot be definitively determined because V < W is not guaranteed (W < V but Z ≥ W creates ambiguity).

Question 6

Given: J > K, K ≥ L, L < M, M ≤ N, N > O. Which conclusion CANNOT be determined?

Accepted Answer

From J > K ≥ L < M ≤ N > O: We know J > L (transitive), M > L (transitive), N > O (given), but the relationship between J and M, J and N, K and M, K and N, L and O, and many others cannot be determined because the chain breaks at L < M, creating two semi-independent segments.

Question 7

A code-breaking system assigns values to letters:
A=1, B=2, C=3, ..., Z=26

For a word, the system:
Step 1: Find the sum of all letter values
Step 2: If the sum is even, divide by 2; if odd, multiply by 3

For the word 'CAT', what is the final output?

Accepted Answer

C=3, A=1, T=20. Sum = 3+1+20 = 24 (even). Step 2: 24÷2 = 12. Final output is 12.

Question 8

A sequence generator follows this rule:
Input: A number N
Step 1: If N is even, divide by 2; if N is odd, multiply by 3 and add 1
Step 2: Repeat Step 1 with the new number
Step 3: Stop when you reach 1

Starting with N = 8, how many steps does it take to reach 1?

Accepted Answer

N = 8 (even) → 8÷2 = 4 (Step 1). N = 4 (even) → 4÷2 = 2 (Step 2). N = 2 (even) → 2÷2 = 1 (Step 3). It takes 3 steps to reach 1.

Question 9

A sorting machine processes a list of numbers:
Step 1: Arrange numbers in ascending order
Step 2: Remove the smallest and largest numbers
Step 3: Find the average of the remaining numbers

For the list [5, 12, 3, 8, 15], what is the final output?

Accepted Answer

Step 1: Ascending order = [3, 5, 8, 12, 15]. Step 2: Remove 3 and 15 → [5, 8, 12]. Step 3: Average = (5+8+12)÷3 = 25÷3 = 8.33.

Question 10

A city is facing a severe water shortage. The municipal corporation has identified that 40% of water is lost due to leaking pipes. Which of the following is the most appropriate course of action?

Accepted Answer

The question tests the ability to identify the most logical and immediate action to address a stated problem.

Question 11

A school observes that student attendance has dropped to 60% in the past month. Teachers report that many students are absent due to illness. What should the school do?

Accepted Answer

This tests the ability to identify appropriate follow-up actions when a problem has a known cause.

Question 12

Given: M < N, N ≤ O, O > P, P ≥ Q, Q < R. Which of the following is INDETERMINATE (cannot be determined)?

Accepted Answer

From M < N ≤ O > P ≥ Q < R: We know M < O (transitive), P < O (transitive), Q < R (given), but the relationship between M and P, M and Q, N and P, N and Q, O and R, and many others cannot be determined from the given constraints.

Question 13

A company notices that its customer service response time has increased from 2 hours to 8 hours over the last quarter. Customer complaints have risen by 30%. Which course of action should be prioritized?

Accepted Answer

This tests the ability to link a problem to its likely cause and identify the most direct solution.

Question 14

Given: A ≤ B, B < C, C ≥ D, D > E, E = F. Which of the following is DEFINITELY FALSE?

Accepted Answer

From A ≤ B < C ≥ D > E = F: We know B < C (definite), D > E (definite), E = F (definite), A < C (transitive), and D > F (transitive). The statement 'E > F' contradicts E = F, making it definitely false.

Question 15

A residential colony experiences frequent power cuts lasting 4-6 hours daily. Residents are unable to work from home and children cannot study. What should the local authority do first?

Accepted Answer

This tests the ability to identify the most urgent and foundational course of action.

Question 16

A machine processes input numbers through the following steps:
Step 1: Multiply the input by 2
Step 2: Add 5 to the result
Step 3: Divide by 3

If the input is 10, what is the final output?

Accepted Answer

Following the three-step process sequentially: Step 1: 10 × 2 = 20. Step 2: 20 + 5 = 25. Step 3: 25 ÷ 3 = 8.33 (or 8⅓). The final output is 8.33.

Question 17

A hospital reports that patient waiting time in the emergency department has increased to 3 hours, and patient satisfaction scores have dropped significantly. The hospital has adequate staff and equipment. What is the most logical course of action?

Accepted Answer

This tests the ability to identify the cause when resources are not the constraint, and choose an appropriate action.

Question 18

A word-processing system transforms words as follows:
Step 1: Count the number of vowels
Step 2: Multiply this count by 2
Step 3: Add the number of consonants

Apply this to the word 'MACHINE'. What is the final output?

Accepted Answer

MACHINE has vowels: A, I, E (3 vowels) and consonants: M, C, H, N (4 consonants). Step 1: 3 vowels. Step 2: 3 × 2 = 6. Step 3: 6 + 4 = 10. Final output is 10.

Question 19

A government school has a 50% dropout rate among girls. Teachers report that many girls leave school to help with household chores and childcare. What should the school administration prioritize?

Accepted Answer

This tests the ability to identify a course of action that addresses a social barrier to education.

Question 20

Given: X ≥ Y, Y > Z, Z ≤ W, W < V, V ≤ X. Which of the following is INDETERMINATE (cannot be determined)?

Accepted Answer

From the given: X ≥ Y > Z ≤ W < V ≤ X. Let's analyze: (a) X > Z: X ≥ Y > Z, so X > Z is TRUE. (b) W ≥ Z: W ≥ Z is given (Z ≤ W), so this is TRUE. (c) V > Y: V ≤ X and X ≥ Y, but this doesn't tell us if V > Y. V could be less than, equal to, or greater than Y. This is INDETERMINATE. (d) Z < X: Z < Y and Y ≤ X, so Z < X is TRUE.
