    • 20 s
    • 25 s
    • 30 s
    • 35 s
Show Answer Correct: Option C. Speed = 200 m /10 s = 20 m/s; distance = 200 + 400 = 600 m; time = 600/20 = 30 s.
  1. The average of 11 numbers is 42. If one number 63 is removed, the new average is
    • 39
    • 40
    • 41
    • 42

  1. A man sells two articles for ₹4,800 each. On one he gains 20 % and on the other he loses 20 %. His overall gain/loss is
    • 4 % gain
    • 4 % loss
    • 2 % loss
    • No gain no loss
Show Answer Correct: Option B. When SP same & % gain = % loss, net loss = (20/10)² = 4 %.
  1. If x + 1/x = 5, then x² + 1/x² equals
    • 23
    • 24
    • 25
    • 27
Show Answer Correct: Option A. Square both sides: x² + 2 + 1/x² = 25 ⇒ x² + 1/x² = 23.
  1. A sum becomes ₹5,500 in 2 years at 10 % simple interest. The principal is
    • ₹4,500
    • ₹4,750
    • ₹5,000
    • ₹5,250
Show Answer Correct: Option C. SI for 2 yr = 20 % of P; A = 1.2P = 5500 ⇒ P = 5500/1.2 = 5000.
  1. The HCF of two numbers is 12 and their LCM is 432. If one number is 48, the other number is
    • 108
    • 96
    • 112
    • 84
Show Answer Correct: Option A. Product = HCF×LCM = 12×432 = 5184; other number = 5184/48 = 108.
  1. A cylindrical rod of radius 3.5 cm and height 20 cm is melted to form spheres of radius 1.75 cm. How many such spheres can be made?
    • 12
    • 24
    • 36
    • 48
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

  1. Find the odd one out:
    • 27
    • 64
    • 125
    • 216
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.)
  1. If DEAF is coded as 4516, what is the code for FADE?
    • 6154
    • 6415
    • 5164
    • 6541
Show Answer Correct: Option B. Letter-position sum: D4+E5+A1+F6=16; reverse order for FADE → F6 A1 D4 E5 → 6415.
  1. A man walks 8 km North, then 6 km East. How far is he from the starting point?
    • 10 km
    • 12 km

    • 48
    • 46
    • 44
    • 42
Show Answer Correct: Option A. Differences: +5, +7, +9, +11, thus next +13 → 35+13=48.
