Question 1

Q1: Pipe A fills a tank in 12 hours, pipe B in 18 hours. How long to fill together?

Solution:

Combined rate = 1/12 + 1/18 = (12+18)/(12×18). Time = 12×18/(12+18) = 7.2 hours.

Answer: 7.2 hours

Question 2

Q2: The ratio of ages of A and B is 2:3. After 6 years, the ratio becomes 3:4. Find A’s present age.

Solution:

Let ages be 2x and 3x.

(2x + 6)/(3x + 6) = 3/4 4(2x + 6) = 3(3x + 6) 8x + 24 = 9x + 18 x = 6 A’s age = 2×6 = 12 years.

Answer: 12 years

Question 3

Q3: A shopkeeper marks goods 40% above cost and gives a 10% discount. Find the profit percentage.

Solution:

Let CP = 100. MP = 140. SP after 10% discount = 126.

Profit % = 126 − 100 = 26%.

Answer: 26%

Question 4

Q4: Simple interest on ₹5000 at 8% per annum for 3 years is?

Solution:

SI = (P × R × T)/100 = (5000 × 8 × 3)/100 = ₹1200.

Answer: ₹1200

Question 5

Q5: Pointing to a photo, Ravi said, ‘He is the son of my grandfather’s only son.’ How is the person related to Ravi?

Solution:

Grandfather’s only son = Ravi’s father. Son of Ravi’s father = Ravi himself (or his brother).

In standard puzzle framing with one son implied for the speaker context: the person is Ravi’s brother (or Ravi). Most campus keys take Brother.

Answer: Brother

Question 6

Q6: Find the next number in the series: 2, 6, 12, 20, 30, ?

Solution:

Pattern: n(n+1): 1×2, 2×3, 3×4, 4×5, 5×6 → next 6×7

Next term = 42.

Answer: 42

Question 7

Q7: Choose the synonym of ‘Genuine’.

In placement verbal sections, ‘Genuine’ is closest in meaning to Authentic among common options.

Answer: Authentic

Question 8

Q8: Arrange the parts into a meaningful sentence: P) to succeed Q) hard work R) is essential S) in any field

Solution:

Natural order: Q-R-P-S → Hard work is essential to succeed in any field.

Answer: QRPS

Question 9: check palindrome

Show solution

Problem Statement: Return true if the string reads the same forward and backward (ignore case).

Example:

Input: "Level"
Output: true

Solution (Java):

public boolean isPalindrome(String s) {
    s = s.toLowerCase();
    int i = 0, j = s.length() - 1;
    while (i < j) {
        if (s.charAt(i++) != s.charAt(j--)) return false;
    }
    return true;
}

Time Complexity: O(n)
Space Complexity: O(1)

Question 10: two sum

Show solution

Problem Statement: Given an array of integers and a target, return indices of two numbers that add up to target.

Example:

Input: nums = [2, 7, 11, 15], target = 9
Output: [0, 1]

Solution (Java):

public int[] twoSum(int[] nums, int target) {
    Map<Integer, Integer> map = new HashMap<>();
    for (int i = 0; i < nums.length; i++) {
        int need = target - nums[i];
        if (map.containsKey(need)) return new int[]{map.get(need), i};
        map.put(nums[i], i);
    }
    return new int[]{};
}

Time Complexity: O(n)
Space Complexity: O(n)

Question 11: merge two sorted lists

Show solution

Problem Statement: Merge two sorted linked lists and return a new sorted list.

Example:

Input: 1→2→4 , 1→3→4
Output: 1→1→2→3→4→4

Solution (Java):

public ListNode mergeTwoLists(ListNode a, ListNode b) {
    ListNode dummy = new ListNode(0), cur = dummy;
    while (a != null && b != null) {
        if (a.val <= b.val) { cur.next = a; a = a.next; }
        else { cur.next = b; b = b.next; }
        cur = cur.next;
    }
    cur.next = (a != null) ? a : b;
    return dummy.next;
}

Time Complexity: O(n + m)
Space Complexity: O(1)
