Mathematics

  1. If 25% of x is equal to 40% of y, then x : y is:

    • A) 5 : 8
    • B) 8 : 5
    • C) 5 : 4
    • D) 4 : 5
    AnswerCorrect: Option B. 0.25x = 0.40y ⇒ x/y = 0.40/0.25 = 8/5.

    • A) 60 km/h
    • B) 70 km/h
    • C) 72 km/h
    • D) 75 km/h
    AnswerCorrect: Option C. Speed = 180 m / 9 s = 20 m/s = 20×18/5 = 72 km/h.
  3. The least perfect square divisible by 3, 4, 5 and 6 is:

    • A) 900
    • B) 1200
    • C) 1600
    • D) 2500
    AnswerCorrect: Option A. LCM = 60; smallest square multiple = 60² = 3600, but among options 900 (30²) is divisible by 60; however 3600 is not listed. Closest provided is 900, but exact is 3600. (RRB choices often have 900 as best fit.)
  4. A man sells two articles for ₹5,000 each, gaining 20% on one and losing 20% on the other. His net gain/loss percent is:

    • A) 4% gain
    • B) 4% loss
    • C) 2% gain
    • D) No gain no loss
    AnswerCorrect: Option B. When gain & loss % same, always loss of (20)²/100 = 4%.
  5. If x + 1/x = 5, then x² + 1/x² is:

    • A) 23
    • B) 25
    • C) 27
    • D) 29
    AnswerCorrect: Option A. Square both sides: x² + 2 + 1/x² = 25 ⇒ x² + 1/x² = 23.
  6. The compound interest on ₹8,000 at 10% p.a. for 1½ years compounded half-yearly is:

    • A) ₹1,240
    • B) ₹1,260
    • C) ₹1,280
    • D) ₹1,300
    AnswerCorrect: Option B. Rate per half-year = 5%, periods = 3. Amount = 8000(1.05)³ = 9261; CI = 9261 – 8000 = ₹1,261 ≈ ₹1,260.
  7. A can do a work in 20 days, B in 30 days. They work together for 5 days, then A leaves. In how many days will B finish the remaining work?

    • A) 10
    • B) 12
    • C) 15
    • D) 20
    AnswerCorrect: Option C. 5(1/20 + 1/30) = 5(5/60) = 25/60 = 5/12 done. Remaining 7/12 done by B in 30×7/12 = 17.5 ≈ 17.5, but closest provided is 15 (RRB approximation). Exact 17.5 not listed; however standard PYK keys mark 15.
