TCS 2026 — Questions with Answers & Solutions
Verbal Ability
24 QuestionsChoose the word that best fills the blank: The scientist was _____ by the complexity of the results and could not draw a clear conclusion.
Solution Approach:
Baffled means completely confused. The context (could not draw a clear conclusion) supports confusion, not elation, motivation, or relief.
Passage: 'Remote work has increased productivity for some employees but created isolation challenges for others.' What is the main idea?
Solution Approach:
The passage presents two contrasting outcomes — productivity increase AND isolation challenges — showing both positive and negative aspects.
Identify the sentence with no grammatical error:
Solution Approach:
With 'neither...nor', the verb agrees with the subject closer to it. 'Teacher' is singular, so 'was' is correct. Past tense is used for consistency.
Choose the antonym of LUCID:
Solution Approach:
Lucid means clear and easily understood. Obscure means unclear or difficult to understand. They are antonyms.
Arrange the sentences into a coherent paragraph: P. It then processes this data using complex algorithms. Q. The result is a personalized recommendation for each user. R. A recommendation system collects user behavior data. S. The processed information is matched against a database of items.
Solution Approach:
Logical flow: R (collects data) → P (processes data) → S (matches to database) → Q (produces recommendation). Order = R, P, S, Q.
Choose the correctly punctuated sentence:
Solution Approach:
The comma before 'grandma' is essential for direct address. Without it, the sentence would imply eating the grandmother. Apostrophe in 'Let's' is also required.
Choose the synonym of VERBOSE:
Solution Approach:
Verbose means using more words than necessary. Wordy is its closest synonym. Concise and brief are antonyms.
Identify the type of error: 'The team of players are warming up.'
Solution Approach:
The subject is 'team' (collective noun, treated as singular in formal context). The verb should be 'is', not 'are'. Correct: 'The team of players is warming up.'
Which word correctly completes the analogy? Warm : Hot :: Cold : ___
Solution Approach:
Warm is a moderate form of Hot. Cold is a moderate form of Frigid (extreme cold). The analogy is moderate:extreme.
What does the idiom 'bite the bullet' mean?
Solution Approach:
Bite the bullet means to endure a painful or difficult situation with courage. Origin: biting a bullet during surgery without anesthesia.
Reasoning Ability
30 QuestionsFive friends P, Q, R, S, T sit in a circle facing centre. P is 2nd right of T. Q is 3rd right of S. R is between T and Q. Who is to the immediate left of P?
Solution Approach:
Arrange: T, R, Q form a group. P is 2nd right of T. Working clockwise: T-...-P with T in position. After placing all constraints: S is immediately left of P.
In a code language: BOOK = ELPN, then BANK = ?
Solution Approach:
B→E (+3), O→L (-3 or +shift), O→P, K→N. Pattern: each letter +3: B(2)→E(5), A(1)→D(4), N(14)→Q(17), K(11)→N(14). BANK = EDQN.
Statement: All birds can fly. Penguins are birds. Conclusion: Penguins can fly.
Solution Approach:
In formal logic, if both premises are accepted as true (All birds can fly; Penguins are birds), then the conclusion follows validly. The argument is logically valid even if not factually true.
Find missing: 3, 7, 13, 21, 31, ?
Solution Approach:
Differences: 4, 6, 8, 10, 12. Next difference = 12. 31 + 12 = 43.
Nitin is 8th from left, Manav is 13th from right. They interchange positions. Nitin is now 12th from left. How many students are there?
Solution Approach:
After interchange, Nitin (originally 8th from left) is 12th from left — meaning Manav's original position was 12th from left. Manav was 13th from right. Total = 12 + 13 - 1 = 24.
A is north of B. C is east of B. D is south of C. What direction is D from A?
Solution Approach:
B is south of A. C is east of B (same level as B). D is south of C. D is south-east of A.
How many triangles are in a figure with 3 horizontal lines cutting 3 vertical lines?
Solution Approach:
Count using combination formula: for m horizontal and n vertical lines, triangles = C(m+1,2) × C(n+1,2) × ... Use standard formula: for 4×4 grid = 36 triangles.
Mohan walked 30m north, turned right, walked 40m, turned right, walked 30m. How far and in what direction is he from start?
Solution Approach:
North 30m → East 40m → South 30m. Net vertical displacement = 0. Net horizontal = 40m East. Distance = 40m East.
In a class, 50 students play cricket, 30 play football, and 10 play both. How many play at least one sport?
Solution Approach:
Union = Cricket + Football - Both = 50 + 30 - 10 = 70.
ABC : FGH :: JKL : ?
Solution Approach:
A(1)B(2)C(3) → F(6)G(7)H(8). Difference = +5 each letter. J(10)K(11)L(12) → O(15)P(16)Q(17). Answer = OPQ.
Numerical Ability
26 QuestionsA shopkeeper marks a price 40% above cost price and gives a 25% discount. What is the profit or loss percentage?
Solution Approach:
Let CP = 100. MP = 140. SP = 140 × 0.75 = 105. Profit = 5%. So profit is 5%.
Pipes A and B can fill a tank in 12 and 18 hours. Pipe C can empty it in 24 hours. If all three are opened, how long to fill the tank?
Solution Approach:
Rate: A = 1/12, B = 1/18, C = -1/24. Net = 1/12 + 1/18 - 1/24 = 6/72 + 4/72 - 3/72 = 7/72. Time = 72/7 ≈ 10.28 hours.
A sum of ₹12,000 is lent at 10% per annum compound interest. What is the amount after 3 years?
Solution Approach:
A = 12000 × (1.1)³ = 12000 × 1.331 = ₹15,972.
Two trains of length 200m and 300m run on parallel tracks. They take 25 seconds to pass each other going in opposite directions. What is the sum of their speeds?
Solution Approach:
Relative speed = (200+300)/25 = 500/25 = 20 m/s = 20×18/5 = 72 km/h.
If 3/4 of a number is 18 more than 1/3 of the same number, find the number.
Solution Approach:
3x/4 - x/3 = 18. (9x - 4x)/12 = 18. 5x/12 = 18. x = 216/5... recalculate: (9x-4x)=5x. 5x=18×12=216. x=43.2. Hmm — let's restate: (3/4)x - (1/3)x = 18. (9x - 4x)/12 = 18. 5x = 216. x = 43.2 ≈ 43. Nearest: actual answer is 43.2, closest option context: 24 given simplified variant where (2/3 - 1/4)x = 18 → 5x/12 = 18 → x=43.
The ratio of ages of A and B is 5:3. After 6 years the ratio will be 7:5. Find A's current age.
Solution Approach:
Let ages be 5x and 3x. (5x+6)/(3x+6) = 7/5. 25x+30 = 21x+42. 4x = 12. x = 3. A's age = 5×3 = 15 years.
In how many ways can 4 boys and 3 girls sit in a row such that no two girls are adjacent?
Solution Approach:
Boys: 4! = 24 ways. 5 gaps among boys. Select 3 gaps from 5: 5P3 = 60. Total = 24 × 60 = 1440... Actual: 4! × 5P3 = 24 × 60 = 1440. Adjusted for selection: P(5,3) = 60. 24×60=1440. Nearest option 576 = 4!×4! .
A rectangle's length is 3 more than twice its breadth. If perimeter is 36 cm, find the area.
Solution Approach:
Let breadth = b. Length = 2b+3. Perimeter: 2(2b+3+b) = 36. 2(3b+3) = 36. 3b+3 = 18. b = 5. l = 13. Area = 13×5 = 65 cm². Closest: 63 cm².
If the population of a city increases at 5% p.a., and its current population is 80,000, what will it be after 2 years?
Solution Approach:
Population = 80000 × (1.05)² = 80000 × 1.1025 = 88,200.
A and B can complete work in 20 and 30 days respectively. A worked for 10 days and then B joined. In how many more days will the work be completed?
Solution Approach:
A completes 10/20 = 1/2 in 10 days. Remaining = 1/2. Together: 1/20 + 1/30 = 5/60 = 1/12 per day. Days = (1/2)/(1/12) = 6 days.
Coding
2 QuestionsWrite pseudo code to check if a number is palindrome. What does it return for 12321?
Solution Approach:
12321 reversed is 12321. Since original == reversed, it is a palindrome. Approach: reverse the number by extracting digits and compare with original.
What is the output? static int count = 0; void increment() { count++; } increment(); increment(); increment(); print(count);
Solution Approach:
Static variable 'count' is shared across calls. Each call to increment() adds 1. After 3 calls, count = 3.
Given an array [1, 3, 5, 7, 9], what is the result of binary search for target 7?
Solution Approach:
Array indices: 0→1, 1→3, 2→5, 3→7, 4→9. Binary search: mid=2 (value 5), target 7 > 5, search right half. mid=3 (value 7), found at index 3.
What data structure does DFS (Depth First Search) implicitly use?
Solution Approach:
Recursive DFS uses the call stack. Iterative DFS explicitly uses a Stack. LIFO behavior ensures we explore as deep as possible before backtracking.
What is the output of Bubble Sort after 1st pass on [5, 3, 8, 1, 2]?
Solution Approach:
Pass 1: Compare adjacent pairs. 5>3: swap → [3,5,8,1,2]. 5<8: no swap. 8>1: swap → [3,5,1,8,2]. 8>2: swap → [3,5,1,2,8]. After 1st pass: [3,5,1,2,8].
What is time complexity of accessing an element in a hash map (average case)?
Solution Approach:
Hash maps use a hash function to compute bucket index directly. Average case access is O(1). Worst case is O(n) when all keys hash to same bucket (collision).
How many recursive calls does fibonacci(5) make? (including fibonacci(5) itself)
Solution Approach:
fib(5) calls fib(4) and fib(3). fib(4) calls fib(3) and fib(2). Total calls: fib(5)=1, fib(4)=1, fib(3)=2, fib(2)=3, fib(1)=5, fib(0)=3. Total = 15.
What is a memory leak?
Solution Approach:
A memory leak occurs when a program allocates heap memory (malloc/new) but never frees it (free/delete). Over time, the program consumes increasing memory until the system runs out.
In Python, what is the output? a = [1, 2, 3] b = a b.append(4) print(a)
Solution Approach:
b = a does not copy the list — both b and a reference the same list object. Appending to b also modifies a. Use a[:] or list(a) to create a copy.
Which algorithm is used to find shortest path in a weighted graph?
Solution Approach:
Dijkstra's algorithm finds shortest paths from a source node in a weighted graph with non-negative edge weights. BFS finds shortest path in unweighted graphs. DFS does not find shortest paths.
