NTT Data Placement Papers 2024 - actual questions & solutions
This section contains practice questions styled on NTT Data 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: 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: 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 3
Q3: Pipe A fills a tank in 10 hours, pipe B in 15 hours. How long to fill together?
Solution:
Combined rate = 1/10 + 1/15 = (10+15)/(10×15). Time = 10×15/(10+15) = 6 hours.
Answer: 6 hours
Question 4
Q4: A number is increased by 10% and then decreased by 10%. Find the net percentage change.
Solution:
Let original = 100. After +10% → 110. After −10% → 110 − 11 = 99.
Net change = 100 − 99 = 1. Net % = 1% decrease (always a loss of (10/10)² %).
Answer: 1% decrease
Question 5
Q5: Statements: All books are goods. Some goods are new. Conclusions: I. Some books are new. II. All goods are books.
Solution:
From the statements, books⊆goods and some goods overlap new. That does not force some books to be new, and ‘all goods are books’ reverses the first statement wrongly.
Neither conclusion follows.
Answer: Neither I nor II follows
Question 6
Q6: In a row of 40 students, A is 12th from the left and B is 14th from the right. How many students are between A and B if A is to the left of B?
Solution:
Positions from left: A = 12, B = 40 − 14 + 1 = 27. Students between = 27 − 12 − 1 = 14.
Answer: 14
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: 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: 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: trueSolution (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 11: first non-repeating character
Show solution
Problem Statement: Return the first non-repeating character in a string, or ‘_’ if none.
Example:
Input: "swiss"Output: 'w'Solution (Java):
public char firstUnique(String s) { int[] freq = new int[256]; for (char c : s.toCharArray()) freq[c]++; for (char c : s.toCharArray()) if (freq[c] == 1) return c; return '_';}Time Complexity: O(n)
Space Complexity: O(1)
