Mindtree Placement Papers 2025 - actual questions & solutions

This section contains practice questions styled on Mindtree placement papers 2025 (recent-cycle 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: Pipe A fills a tank in 10 hours, pipe B in 15 hours. How long to fill together?

Solution:

Combined rate = 1/10 + 1/15 = (10+15)/(10×15). Time = 10×15/(10+15) = 6 hours.

Answer: 6 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 number is increased by 10% and then decreased by 10%. Find the net percentage change.

Solution:

Let original = 100. After +10% → 110. After −10% → 110 − 11 = 99.

Net change = 100 − 99 = 1. Net % = 1% decrease (always a loss of (10/10)² %).

Answer: 1% decrease

Question 4

Q4: 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 5

Q5: In a row of 50 students, A is 8th from the left and B is 11th from the right. How many students are between A and B if A is to the left of B?

Solution:

Positions from left: A = 8, B = 50 − 11 + 1 = 40. Students between = 40 − 8 − 1 = 31.

Answer: 31

Question 6

Q6: 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 7

Q7: Choose the antonym of ‘Expand’.

Solution:

‘Expand’ means roughly the opposite of Contract.

Answer: Contract

Question 8

Q8: Fill in the blank: ‘She has been working here _____ 2019.’

Solution:

Use since with a point in time; use for with a duration.

Correct: since.

Answer: since

Question 9: reverse a string

Show solution

Problem Statement: Given a string, return it reversed.

Example:

Input: "placement"
Output: "tnemecalp"

Solution (Java):

public String reverse(String s) {
    return new StringBuilder(s).reverse().toString();
}

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

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: 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)
