NTT Data Placement Papers 2025 - actual questions & solutions

This section contains practice questions styled on NTT Data 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 shopkeeper marks goods 40% above cost and gives a 10% discount. Find the profit percentage.

Solution:

Let CP = 100. MP = 140. SP after 10% discount = 126.

Profit % = 126 − 100 = 26%.

Answer: 26%

Question 2

Q2: 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 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 20% and then decreased by 20%. Find the net percentage change.

Solution:

Let original = 100. After +20% → 120. After −20% → 120 − 24 = 96.

Net change = 100 − 96 = 4. Net % = 4% decrease (always a loss of (20/10)² %).

Answer: 4% decrease

Question 5

Q5: In a row of 50 students, A is 9th 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 = 9, B = 50 − 11 + 1 = 40. Students between = 40 − 9 − 1 = 30.

Answer: 30

Question 6

Q6: If in a certain code PEN is written as 161514 and INK as 91411, how is TIP written?

Solution:

Pattern: positions concatenated T=20,I=9,P=16

Therefore TIP → 20916.

Answer: 20916

Question 7

Q7: Choose the synonym of ‘Diligent’.

Solution:

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

Answer: Hardworking

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: 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)

Question 11: valid parentheses

Show solution

Problem Statement: Given a string of brackets, determine if it is valid.

Example:

Input: "()[]{}"
Output: true

Solution (Java):

public boolean isValid(String s) {
    Deque<Character> st = new ArrayDeque<>();
    Map<Character, Character> pair = Map.of(')', '(', ']', '[', '}', '{');
    for (char c : s.toCharArray()) {
        if (pair.containsValue(c)) st.push(c);
        else if (st.isEmpty() || st.pop() != pair.get(c)) return false;
    }
    return st.isEmpty();
}

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