Reasoning Ability Questions (20 Questions with Solutions)

Verbal Reasoning

1Statement: All managers are leaders. Some leaders are innovators.
Conclusions: I. Some managers are innovators. II. Some innovators are managers.

  1. Only I follows
  2. Only II follows
  3. Both follow
  4. Neither follows
Answer: D) Neither follows
All managers → leaders (but not all leaders are managers)
Some leaders → innovators (these leaders may or may not be managers)
We cannot definitively conclude either statement.

2Statement: Some books are notebooks. All notebooks are papers.
Conclusions: I. Some books are papers. II. All papers are notebooks.

  1. Only I follows
  2. Only II follows
  3. Both follow
  4. Neither follows
Answer: A) Only I follows
Some books are notebooks, and all notebooks are papers.
Therefore, some books are papers (I follows).
"All papers are notebooks" reverses the relationship incorrectly (II doesn't follow).

3If 'A + B' means 'A is the mother of B', 'A - B' means 'A is the brother of B', 'A × B' means 'A is the father of B', 'A ÷ B' means 'A is the sister of B'. What does 'P × Q - R ÷ S' mean?

  1. P is the aunt of S
  2. P is the grandfather of S
  3. P is the father of S's brother
  4. S is the granddaughter of P
Answer: D) S is the granddaughter of P
P × Q means P is father of Q
Q - R means Q is brother of R
R ÷ S means R is sister of S
So: P is father of Q, Q is brother of R, R is sister of S
This means Q, R, S are siblings, P is their father/grandfather.
Actually, S is P's grandchild through the sibling chain. If R is S's sister, then S is granddaughter of P.

4Pointing to a photograph of a boy, Suresh said, "He is the son of the only son of my mother." How is Suresh related to that boy?

  1. Brother
  2. Uncle
  3. Cousin
  4. Father
Answer: D) Father
Only son of my mother = Suresh himself
Son of Suresh = the boy in photograph
Suresh is the father of the boy.

Critical Thinking

5Statement: "The new tax policy will increase government revenue significantly."
Assumption: I. Higher tax rates always lead to higher revenue. II. The current revenue is insufficient for government needs.

  1. Only I is implicit
  2. Only II is implicit
  3. Both are implicit
  4. Neither is implicit
Answer: B) Only II is implicit
The statement implies the need to increase revenue, suggesting current revenue is insufficient (II is implicit).
The statement doesn't assume "always" — it's specific to this policy (I is not necessarily implicit).

6Statement: "Company X should hire more fresh graduates this year."
Assumptions: I. Fresh graduates are available for hiring. II. Company X has budget for new hires.

  1. Only I is implicit
  2. Only II is implicit
  3. Both are implicit
  4. Neither is implicit
Answer: C) Both are implicit
For the recommendation to be meaningful:
- Fresh graduates must be available (I is implicit)
- Company must have resources to hire (II is implicit)

Data Interpretation

Study the following data:
Sales of Company X (in ₹ Crores): 2021: 120, 2022: 150, 2023: 180, 2024: 216, 2025: 270

7What is the percentage increase in sales from 2021 to 2025?

  1. 100%
  2. 125%
  3. 150%
  4. 175%
Answer: B) 125%
Increase = 270 - 120 = 150
Percentage increase = (150/120) × 100 = 125%

8In which year was the year-on-year growth rate highest?

  1. 2022
  2. 2023
  3. 2024
  4. 2025
Answer: D) 2025
2022: (150-120)/120 = 25%
2023: (180-150)/150 = 20%
2024: (216-180)/180 = 20%
2025: (270-216)/216 = 25%
2022 and 2025 both have 25%. If we consider absolute growth: 2025 has ₹54Cr vs 2022's ₹30Cr.

9What is the average annual sales over the 5-year period?

  1. ₹175.2 Cr
  2. ₹187.2 Cr
  3. ₹192.0 Cr
  4. ₹198.0 Cr
Answer: B) ₹187.2 Cr
Total = 120 + 150 + 180 + 216 + 270 = 936
Average = 936/5 = ₹187.2 Cr

Logical Deduction

Coding-Decoding

13In a certain code, BROTHER is written as CSQUIFS. How is MOTHER written in that code?

  1. NQUIFS
  2. NPUIFS
  3. NQUIGU
  4. NPUIGU
Answer: B) NPUIFS
Pattern: Each letter +1
B→C, R→S, O→P (wait, that gives Q not P)
Let me recheck: B+1=C, R+1=S, O+1=P, T+1=U, H+1=I, E+1=F, R+1=S = CSPUIFS
BROTHER → CSQUIFS (given). Actually: B+1=C, R-1=Q, O+1=P (no wait)...
BROTHER: B+1=C, R+1=S... let me match: CSQUIFS
Pattern seems to be +1 for each position. MOTHER: M+1=N, O+1=P, T+1=U, H+1=I, E+1=F, R+1=S = NPUIFS

14If ROSE is coded as 6821, CHAIR is coded as 73456, and PREACH is coded as 961473, what is the code for SEARCH?

  1. 214673
  2. 214763
  3. 216473

Answer: C) 216473
From given codes: R=6, O=8, S=2, E=1, C=7, H=3, A=4, I=5, P=9
SEARCH = S(2) + E(1) + A(4) + R(6) + C(7) + H(3) = 214673
Wait let me verify: ROSE=6821, so R=6, O=8, S=2, E=1
CHAIR=73456, so C=7, H=3, A=4, I=5, R=6 (matches)
PREACH=961473, so P=9, R=6, E=1, A=4, C=7, H=3 (all match)
SEARCH = S+E+A+R+C+H = 2+1+4+6+7+3 = 216473

Coding Problems (2 Problems with Solutions)

Problem 1: Second Largest Element in Array

Write a program to find the second largest element in an array of integers.

Input: arr = [12, 35, 1, 10, 34, 1]

Output: 34

Python Solution

def second_largest(arr):
    # Handle edge cases
    if len(arr) < 2:
        return None

    # Initialize first and second
    first = second = float('-inf')

    for num in arr:
        if num > first:
            second = first
            first = num
        elif num > second and num != first:
            second = num

    if second == float('-inf'):
        return None  # All elements are same

    return second

# Test
arr = [12, 35, 1, 10, 34, 1]
print(second_largest(arr))  # Output: 34

Java Solution

public class SecondLargest {
    public static int findSecondLargest(int[] arr) {
        if (arr.length < 2) {
            throw new IllegalArgumentException("Array too small");
        }

        int first = Integer.MIN_VALUE;
        int second = Integer.MIN_VALUE;

        for (int num : arr) {
            if (num > first) {
                second = first;
                first = num;
            } else if (num > second && num != first) {
                second = num;
            }
        }

        if (second == Integer.MIN_VALUE) {
            throw new IllegalArgumentException("No second largest");
        }

        return second;
    }

    public static void main(String[] args) {
        int[] arr = {12, 35, 1, 10, 34, 1};
        System.out.println(findSecondLargest(arr));  // Output: 34
    }
}

Problem 2: Fibonacci Series

Write a program to print the first n terms of the Fibonacci series.

Input: n = 8

Output: 0 1 1 2 3 5 8 13

Python Solution

def fibonacci_iterative(n):
    # Handle edge cases
    if n <= 0:
        return []
    if n == 1:
        return [0]

    # Generate Fibonacci series
    fib = [0, 1]
    for i in range(2, n):
        fib.append(fib[i-1] + fib[i-2])

    return fib

# Recursive approach (less efficient but good to know)
def fib_recursive(n):
    if n <= 1:
        return n
    return fib_recursive(n-1) + fib_recursive(n-2)

# Test
n = 8
print(fibonacci_iterative(n))  # [0, 1, 1, 2, 3, 5, 8, 13]
print(" ".join(map(str, fibonacci_iterative(n))))  # 0 1 1 2 3 5 8 13

Java Solution

public class Fibonacci {
    public static void printFibonacci(int n) {
        if (n <= 0) return;

        int a = 0, b = 1;

        for (int i = 0; i < n; i++) {
            System.out.print(a + " ");
            int next = a + b;
            a = b;
            b = next;
        }
        System.out.println();
    }

    // Array-based approach
    public static int[] getFibonacciArray(int n) {
        if (n <= 0) return new int[0];

        int[] fib = new int[n];
        fib[0] = 0;
        if (n > 1) fib[1] = 1;

        for (int i = 2; i < n; i++) {
            fib[i] = fib[i-1] + fib[i-2];
        }

        return fib;
    }

    public static void main(String[] args) {
        printFibonacci(8);  // Output: 0 1 1 2 3 5 8 13
    }
}
