Capital One Placement Papers 2024 - actual questions & solutions

This section contains practice questions styled on Capital One placement papers 2024 (previous-year pattern), with worked solutions. Use them as timed sectional drills - from student reports drives vary by college and role, so treat this as a high-signal practice bank, not an official paper dump.

Question 1

Q1: A number is increased by 25% and then decreased by 25%. Find the net percentage change.

Solution:

Let original = 100. After +25% → 125. After −25% → 125 − 31.25 = 93.75.

Net change = 100 − 93.75 = 6.25. Net % = 6.25% decrease (always a loss of (25/10)² %).

Answer: 6.25% decrease

Question 2

Q2: 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 3

Q3: A train 240 m long crosses a pole in 16 seconds. Find its speed in km/h.

Solution:

Speed = distance/time = 240/16 m/s = (240/16) × (18/5) = 54 km/h.

Answer: 54 km/h

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: Statements: All papers are goods. Some goods are new. Conclusions: I. Some papers are new. II. All goods are papers.

Solution:

From the statements, papers⊆goods and some goods overlap new. That does not force some papers to be new, and ‘all goods are papers’ reverses the first statement wrongly.

Neither conclusion follows.

Answer: Neither I nor II follows

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: Identify the error: ‘Neither of the boys have submitted their assignment.’

Solution:

‘Neither’ is singular → verb should be has, not have.

Correct: Neither of the boys has submitted his/their assignment.

Answer: have → has

Question 9: 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 10: 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 11: valid parentheses

Show solution

Problem Statement: Given a string of brackets, determine if it is valid.

Example:

Input: "()[]{}"
Output: true

Solution (Java):

public boolean isValid(String s) {
    Deque<Character> st = new ArrayDeque<>();
    Map<Character, Character> pair = Map.of(')', '(', ']', '[', '}', '{');
    for (char c : s.toCharArray()) {
        if (pair.containsValue(c)) st.push(c);
        else if (st.isEmpty() || st.pop() != pair.get(c)) return false;
    }
    return st.isEmpty();
}

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