Aptitude Questions (15 with Solutions)

Q1: A alone does work in 10 days, B in 15 days. With C, they finish in 5 days. C alone?

Solution: 1/10 + 1/15 + 1/C = 1/5 → 1/C = 1/5 - 1/6 = 1/30. C = 30 days

Q2: A pipe fills in 4 hours, another empties in 6 hours. Both open?

Solution: 1/4 - 1/6 = 1/12. 12 hours to fill

Q3: A:B = 3:4, B:C = 5:6. Find A:C.

Solution: A:B:C = 15:20:24. A:C = 15:24 = 5:8

Q4: Average of 5 numbers is 27. If one excluded, average is 25. Find excluded number.

Solution: Total = 135, New total = 100. Excluded = 35

Q5: 20% discount, then 10% cash discount. Equivalent single discount?

Solution: 0.80 × 0.90 = 0.72. Discount = 28%

Q6: A invests ₹12000, B ₹15000. After 8 months, C joins ₹18000. Year profit ₹42000. Find C's share.

Solution: Ratio: 12000×12 : 15000×12 : 18000×4 = 144:180:72 = 4:5:2. C's share = (2/11)×42000 = ₹7636

Q7: SP of 12 articles = CP of 15 articles. Profit%?

Solution: 12SP = 15CP → SP/CP = 5/4. Profit = 25%

Q8: A man rows at 8 km/h in still water. Upstream takes twice as long as downstream. Stream speed?

Solution: Let stream = s. 8+s = 2(8-s) → 8+s = 16-2s → 3s=8 → s = 8/3 km/h

Q9: Probability of getting at least one head in 3 coin tosses.

Solution: 1 - P(all tails) = 1 - 1/8 = 7/8

Q10: Find odd: 2, 5, 10, 17, 26, 38

Solution: n²+1 pattern: 1+1, 4+1, 9+1, 16+1, 25+1, 36+1. 38 should be 37. 38 is odd

Q11: Statement: All flowers are beautiful. Some beautiful things are red. Conclusion: Some flowers are red.

Solution: Does not follow (undistributed middle)

Q12: Coding: SING=52, RING=47. Find KING.

Solution: Positions sum with pattern. S(19)+I(9)+N(14)+G(7)=49? Close. Try: S(19)-? =52. Alternative: Reverse positions. K(11)+I(9)+N(14)+G(7)=41

Q13: A is 10m north of B. C is 10m east of A. D is 10m south of C. Distance BD?

Solution: Forms square. BD = 10√2 m (diagonal)

Q14: Find next: Z, W, T, Q, ?

Solution: -3 each: Z(26)→W(23)→T(20)→Q(17)→N(14)

Q15: In a row, A is 8th from left, B is 9th from right. After swapping, A is 15th from left. Total?

Solution: A's new pos = B's old pos = 15th from left, 9th from right. Total = 15+9-1 = 23

Technical Questions (10 with Solutions)

Q1: What is pair programming?

Solution: Two developers working together at one workstation - one writes code (driver), one reviews (navigator).

Q2: Explain TDD (Test Driven Development).

Solution: Write failing test first, then write code to pass, then refactor. Red-Green-Refactor cycle.

Q3: What is the difference between unit and integration testing?

Solution: Unit tests individual components in isolation. Integration tests how components work together.

Q4: Explain the SOLID principles.

Solution: S-Single Responsibility, O-Open/Closed, L-Liskov Substitution, I-Interface Segregation, D-Dependency Inversion.

Q5: What is continuous integration?

Solution: Practice of merging code changes frequently, with automated builds and tests.

Q6: Difference between abstract class and interface?

Solution: Abstract class can have implementation; interface traditionally only declarations (Java 8+ allows defaults).

Q7: What is dependency injection?

Solution: Design pattern where object receives dependencies from external source rather than creating them.

Q8: Explain agile vs waterfall.

Solution: Waterfall: sequential phases. Agile: iterative, incremental, adaptive to change.

Q9: What is refactoring?

Solution: Improving code structure without changing external behavior. Improves readability and maintainability.

Q10: What is clean code?

Solution: Code that is readable, maintainable, testable, follows conventions, and expresses intent clearly.
