Mindtree Placement Papers 2024 - actual questions & solutions

This section contains practice questions styled on Mindtree 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 2:3. After 6 years, the ratio becomes 3:4. Find A’s present age.

Solution:

Let ages be 2x and 3x.

(2x + 6)/(3x + 6) = 3/4 4(2x + 6) = 3(3x + 6) 8x + 24 = 9x + 18 x = 6 A’s age = 2×6 = 12 years.

Answer: 12 years

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: 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 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: 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: If in a certain code CAT is written as 3120 and DOG as 4157, how is BAT written?

Solution:

Pattern: letter positions: B=2,A=1,T=20

Therefore BAT → 2120.

Answer: 2120

Question 7

Q7: Choose the antonym of ‘Optimistic’.

Solution:

‘Optimistic’ means roughly the opposite of Pessimistic.

Answer: Pessimistic

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: 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 10: 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 11: check palindrome

Show solution

Problem Statement: Return true if the string reads the same forward and backward (ignore case).

Example:

Input: "Level"
Output: true

Solution (Java):

public boolean isPalindrome(String s) {
    s = s.toLowerCase();
    int i = 0, j = s.length() - 1;
    while (i < j) {
        if (s.charAt(i++) != s.charAt(j--)) return false;
    }
    return true;
}

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