Larsen & Toubro Placement Papers 2024 - actual questions & solutions

This section contains practice questions styled on Larsen & Toubro 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: 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 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 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 4

Q4: Pipe A fills a tank in 12 hours, pipe B in 18 hours. How long to fill together?

Solution:

Combined rate = 1/12 + 1/18 = (12+18)/(12×18). Time = 12×18/(12+18) = 7.2 hours.

Answer: 7.2 hours

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: Find the next number in the series: 8, 6, 9, 23, 87, ?

Solution:

Pattern: ×1+6? Classic: ×1−2, ×2−3, ×3−4, ×4−5 → 8×1−2=6, 6×2−3=9, 9×3−4=23, 23×4−5=87, 87×5−6=429

Next term = 429.

Answer: 429

Question 7

Q7: Virtual memory is typically implemented using?

Solution:

OS uses demand paging (and sometimes segmentation) to implement virtual memory.

Answer: Demand paging

Question 8

Q8: Which data structure uses FIFO order?

Solution:

FIFO = First In First Out → Queue. Stack is LIFO.

Answer: Queue

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: rotate array right by k

Show solution

Problem Statement: Rotate the array to the right by k steps.

Example:

Input: [1,2,3,4,5,6,7], k = 3
Output: [5,6,7,1,2,3,4]

Solution (Java):

public void rotate(int[] nums, int k) {
    k %= nums.length;
    reverse(nums, 0, nums.length - 1);
    reverse(nums, 0, k - 1);
    reverse(nums, k, nums.length - 1);
}
void reverse(int[] a, int l, int r) {
    while (l < r) { int t = a[l]; a[l++] = a[r]; a[r--] = t; }
}

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