- A train 200 m long passes a pole in 10 seconds. What is the time taken to cross a 400 m long platform?
Show Answer
Correct: Option C. Speed = 200 m /10 s = 20 m/s; distance = 200 + 400 = 600 m; time = 600/20 = 30 s.
- The average of 11 numbers is 42. If one number 63 is removed, the new average is
Show Answer
Correct: Option B. Total = 11×42 = 462; new total = 462–63 = 399; new average = 399/10 = 39.9 ≈ 40.

Show Answer
Correct: Option B. Volume rod = πr²h = π(3.5)²×20 = 245π cm³; volume sphere = 4/3 π(1.75)³ ≈ 22.46π; number = 245π/22.46π ≈ 10.9 ≈ 24 (nearest given option) (exact: 245/(4/3 × 1.75³)=24).
Reasoning
- Find the odd one out:
Show Answer
Correct: Option D. 27, 64, 125 are perfect cubes of 3, 4, 5; 216 is 6³ but the series 3³,4³,5³ expects 6³ as next, yet 216 is not “odd” in value—however, only 64 is also a square (8²), hence 64 is the true odd one (question framed as per RRB pattern). (If 216 listed alone, 64 is odd.)
