Question 1

Q1: Average of 5 numbers is 20. If one number 15 is replaced by 25, what is the new average?

Solution:

Old sum = 5 × 20 = 100. New sum = 100 − 15 + 25 = 110. New average = 110/5 = 22.

Answer: 22

Question 2

Q2: Simple interest on ₹8000 at 10% per annum for 2 years is?

Solution:

SI = (P × R × T)/100 = (8000 × 10 × 2)/100 = ₹1600.

Answer: ₹1600

Question 3

Q3: A and B together finish a job in 12 days. B alone takes 18 days. How many days does A alone take?

Solution:

Together rate = 1/12. B’s rate = 1/18.

A’s rate = 1/12 − 1/18 = (18−12)/(12×18) = 6/216. Days for A alone = 216/6 = 36 days.

Answer: 36 days

Question 4

Q4: A train 180 m long crosses a pole in 12 seconds. Find its speed in km/h.

Solution:

Speed = distance/time = 180/12 m/s = (180/12) × (18/5) = 54 km/h.

Answer: 54 km/h

Question 5

Q5: If in a certain code CAT is written as 3120 and DOG as 4157, how is BAT written?

Solution:

Pattern: letter positions: B=2,A=1,T=20

Therefore BAT → 2120.

Answer: 2120

Question 6

Q6: 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 7

Q7: 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 8

Q8: Choose the antonym of ‘Scarce’.

Solution:

‘Scarce’ means roughly the opposite of Abundant.

Answer: Abundant

Question 9: detect cycle in linked list

Show solution

Problem Statement: Return true if the linked list has a cycle.

Example:

Input: 3→2→0→-4→(back to 2)
Output: true

Solution (Java):

public boolean hasCycle(ListNode head) {
    ListNode slow = head, fast = head;
    while (fast != null && fast.next != null) {
        slow = slow.next;
        fast = fast.next.next;
        if (slow == fast) return true;
    }
    return false;
}

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

Question 10: binary tree level order

Show solution

Problem Statement: Return the level-order traversal of a binary tree.

Example:

Input: [3,9,20,null,null,15,7]
Output: [[3],[9,20],[15,7]]

Solution (Java):

public List<List<Integer>> levelOrder(TreeNode root) {
    List<List<Integer>> res = new ArrayList<>();
    if (root == null) return res;
    Queue<TreeNode> q = new ArrayDeque<>();
    q.add(root);
    while (!q.isEmpty()) {
        int sz = q.size();
        List<Integer> level = new ArrayList<>();
        for (int i = 0; i < sz; i++) {
            TreeNode n = q.poll();
            level.add(n.val);
            if (n.left != null) q.add(n.left);
            if (n.right != null) q.add(n.right);
        }
        res.add(level);
    }
    return res;
}

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

Question 11: maximum subarray sum

Show solution

Problem Statement: Find the contiguous subarray with the largest sum.

Example:

Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4]
Output: 6  // [4, -1, 2, 1]

Solution (Java):

public int maxSubArray(int[] nums) {
    int best = nums[0], cur = nums[0];
    for (int i = 1; i < nums.length; i++) {
        cur = Math.max(nums[i], cur + nums[i]);
        best = Math.max(best, cur);
    }
    return best;
}

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