Mu Sigma Placement Papers 2025 - actual questions & solutions

This section contains practice questions styled on Mu Sigma 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: 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 2

Q2: 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 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: The ratio of ages of A and B is 3:5. After 10 years, the ratio becomes 5:7. Find A’s present age.

Solution:

Let ages be 3x and 5x.

(3x + 10)/(5x + 10) = 5/7 7(3x + 10) = 5(5x + 10) 21x + 70 = 25x + 50 x = 5 A’s age = 3×5 = 15 years.

Answer: 15 years

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: Statements: All pens are items. Some items are cheap. Conclusions: I. Some pens are cheap. II. All items are pens.

Solution:

From the statements, pens⊆items and some items overlap cheap. That does not force some pens to be cheap, and ‘all items are pens’ reverses the first statement wrongly.

Neither conclusion follows.

Answer: Neither I nor II follows

Question 7

Q7: 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 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: 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: climbing stairs

Show solution

Problem Statement: You can climb 1 or 2 steps. How many distinct ways to climb n stairs?

Example:

Input: n = 4
Output: 5

Solution (Java):

public int climbStairs(int n) {
    if (n <= 2) return n;
    int a = 1, b = 2;
    for (int i = 3; i <= n; i++) {
        int c = a + b; a = b; b = c;
    }
    return b;
}

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

Question 11: 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)
