Larsen & Toubro Placement Papers 2025 - actual questions & solutions

This section contains practice questions styled on Larsen & Toubro 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: 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 2

Q2: 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 3

Q3: Average of 6 numbers is 18. If one number 12 is replaced by 24, what is the new average?

Solution:

Old sum = 6 × 18 = 108. New sum = 108 − 12 + 24 = 120. New average = 120/6 = 20.

Answer: 20

Question 4

Q4: 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 5

Q5: Find the next number in the series: 1, 4, 9, 16, 25, ?

Solution:

Pattern: Perfect squares 1²…5² → next 6²

Next term = 36.

Answer: 36

Question 6

Q6: In a row of 50 students, A is 9th from the left and B is 9th from the right. How many students are between A and B if A is to the left of B?

Solution:

Positions from left: A = 9, B = 50 − 9 + 1 = 42. Students between = 42 − 9 − 1 = 32.

Answer: 32

Question 7

Q7: Which protocol is connection-oriented at the transport layer?

Solution:

TCP is connection-oriented; UDP is connectionless.

Answer: TCP

Question 8

Q8: In OOP, hiding internal details and showing only essential features is called?

Solution:

This is the definition of Encapsulation (often paired with abstraction in interviews).

Answer: Encapsulation

Question 9: longest common prefix

Show solution

Problem Statement: Find the longest common prefix string amongst an array of strings.

Example:

Input: ["flower","flow","flight"]
Output: "fl"

Solution (Java):

public String longestCommonPrefix(String[] strs) {
    if (strs.length == 0) return "";
    String pref = strs[0];
    for (int i = 1; i < strs.length; i++) {
        while (!strs[i].startsWith(pref)) {
            pref = pref.substring(0, pref.length() - 1);
            if (pref.isEmpty()) return "";
        }
    }
    return pref;
}

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

Question 10: 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)

Question 11: 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)
