HCL Placement Papers 2025 - actual questions & solutions

This section contains practice questions styled on HCL 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: A train 180 m long crosses a pole in 12 seconds. Find its speed in km/h.

Solution:

Speed = distance/time = 180/12 m/s = (180/12) × (18/5) = 54 km/h.

Answer: 54 km/h

Question 2

Q2: A and B together finish a job in 8 days. B alone takes 24 days. How many days does A alone take?

Solution:

Together rate = 1/8. B’s rate = 1/24.

A’s rate = 1/8 − 1/24 = (24−8)/(8×24) = 16/192. Days for A alone = 192/16 = 12 days.

Answer: 12 days

Question 3

Q3: 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 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: Statements: All pens are goods. Some goods are new. Conclusions: I. Some pens are new. II. All goods are pens.

Solution:

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

Neither conclusion follows.

Answer: Neither I nor II follows

Question 6

Q6: 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 7

Q7: Choose the antonym of ‘Expand’.

Solution:

‘Expand’ means roughly the opposite of Contract.

Answer: Contract

Question 8

Q8: Choose the synonym of ‘Fragile’.

Solution:

In placement verbal sections, ‘Fragile’ is closest in meaning to Delicate among common options.

Answer: Delicate

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: two sum

Show solution

Problem Statement: Given an array of integers and a target, return indices of two numbers that add up to target.

Example:

Input: nums = [2, 7, 11, 15], target = 9
Output: [0, 1]

Solution (Java):

public int[] twoSum(int[] nums, int target) {
    Map<Integer, Integer> map = new HashMap<>();
    for (int i = 0; i < nums.length; i++) {
        int need = target - nums[i];
        if (map.containsKey(need)) return new int[]{map.get(need), i};
        map.put(nums[i], i);
    }
    return new int[]{};
}

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

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)
