Campus recruitment tests follow their own rhythm: a fixed time limit, a mix of sections, and negative marking that punishes guessing. This collection mirrors that format with quantitative aptitude, logical reasoning, verbal ability, and technical questions of the kind IT and core companies actually ask. Use it to build exam stamina, not just to check whether you know a topic.
What is the time complexity of binary search algorithm?
Answer: C
Binary search has a time complexity of O(log n) because it divides the search space by half in each iteration. This works only on sorted arrays.
Q.225Medium
A train travels from City A to City B at 60 km/h and returns at 40 km/h. If the total journey time is 10 hours, what is the distance between the two cities?
Answer: A
Let distance = d. Time = Distance/Speed. Going: d/60, Returning: d/40. Total: d/60 + d/40 = 10. Taking LCM: (2d + 3d)/120 = 10, so 5d/120 = 10, therefore d = 240 km.
Q.226Medium
In a logical sequence: 2, 6, 12, 20, 30, ?, what is the next number?
Answer: B
The pattern is n(n+1) where n = 1,2,3,4,5,6... First term: 1×2=2, Second: 2×3=6, Third: 3×4=12, Fourth: 4×5=20, Fifth: 5×6=30, Sixth: 6×7=42.
Q.227Medium
Select the word that best completes the analogy: Ephemeral is to Permanent as Verbose is to ____
Answer: B
Ephemeral (short-lived) is opposite to Permanent (long-lasting). Similarly, Verbose (using many words) is opposite to Concise (using few words). The analogy requires antonyms.
Q.228Medium
Two pipes A and B can fill a tank in 12 hours and 18 hours respectively. How long will it take to fill the tank if both pipes are opened together?
Answer: B
Rate of A = 121, Rate of B = 181. Combined rate = 121 + 181 = 365. Time = 536 = 7.2 hours
Q.229Medium
If a number is divided by 7, it leaves a remainder of 4. If the same number is divided by 11, what could be the remainder?
Answer: D
The number could be 11, 18, 25, 32, etc. (of form 7k+4). When divided by 11, remainders vary: 11→0, 18→7, 25→3, 32→10. Cannot determine uniquely.
Q.230Medium
A person covers 60% of a journey by train, 30% by bus, and the remaining distance of 20 km by walk. What is the total distance?
Answer: D
Train + Bus = 60% + 30% = 90%. Walk = 10% = 20 km. Total = 020.10 = 200 km
Q.231Medium
Three numbers are in the ratio 2:3:5. If their sum is 100, what is the largest number?
Answer: C
Let numbers be 2x, 3x, 5x. Sum = 2x + 3x + 5x = 10x = 100. x = 10. Largest = 5x = 50
Q.232Medium
A number when divided by 12 leaves remainder 5. What is the remainder when the number is divided by 4?
Answer: B
Number = 12k + 5. When divided by 4: 12k + 5 = 4(3k) + 4 + 1 = 4(3k+1) + 1. Remainder = 1
Q.233Medium
If 5 workers can build a wall in 12 days, how many days will 10 workers take?
Answer: B
Work is inversely proportional to number of workers. (5 × 12) = (10 × x), so x = 6 days
Q.234Medium
If a person buys 10 items at Rs. 50 each and sells them at Rs. 60 each, what is the profit percentage?
