RRB Group D 2022 PYQ-pattern questions

Showing 10 of the 18 PYQ-pattern questions in this set — freshly worded in that year's pattern, not the original questions. Answers and solutions open under each question.

  1. Q1 · LCM and HCF

    The HCF and LCM of two numbers are 18 and 1260 respectively. If one number is 126, find the other number.

    • A. 162
    • B. 180
    • C. 198
    • D. 216
    Answer and solution

    Answer: B

    Using the formula: Product of two numbers = HCF × LCM. So, 126 × other number = 18 × 1260. Other number = (18 × 1260) / 126 = 180.

  2. Q2 · Number System

    The sum of two numbers is 45 and their HCF is 5. How many such pairs of numbers are possible?

    • A. 2
    • B. 3
    • C. 4
    • D. 5
    Answer and solution

    Answer: B

    Let numbers be 5a, 5b with a,b coprime. Sum 5(a+b)=45 gives a+b=9. Coprime pairs summing to 9: (1,8),(2,7),(4,5). Check gcds: gcd(1,8)=1, gcd(2,7)=1, gcd(4,5)=1, gcd(3,6)=3 excluded. So 3 pairs.

  3. Q3 · Mensuration

    Find the area of a circle whose radius is 14 cm. (Use π = 22/7)

    • A. 484 cm²
    • B. 528 cm²
    • C. 616 cm²
    • D. 704 cm²
    Answer and solution

    Answer: C

    Area = πr² = (22/7) × 14 × 14 = 22 × 2 × 14 = 616 cm².

  4. Q4 · Elementary Statistics

    The average of five numbers is 42. If one number is excluded, the average becomes 40. What is the excluded number?

    • A. 45
    • B. 48
    • C. 50
    • D. 52
    Answer and solution

    Answer: C

    Sum of 5 numbers = 42 × 5 = 210. Sum of 4 numbers = 40 × 4 = 160. Excluded number = 210 - 160 = 50.

  5. Q5 · Square Root

    What is the square root of 256?

    • A. 14
    • B. 15
    • C. 16
    • D. 17
    Answer and solution

    Answer: C

    √256 = 16, since 16 × 16 = 256.

  6. Q6 · Algebra

    If 3x + 7 = 22, then what is the value of x?

    • A. 4
    • B. 5
    • C. 6
    • D. 7
    Answer and solution

    Answer: B

    3x = 22 - 7 = 15, so x = 15 ÷ 3 = 5.

  7. Q7 · LCM and HCF

    Find the LCM of 12, 18, and 24.

    • A. 48
    • B. 72
    • C. 96
    • D. 144
    Answer and solution

    Answer: B

    Prime factorization: 12 = 2² × 3, 18 = 2 × 3², 24 = 2³ × 3. LCM = 2³ × 3² = 8 × 9 = 72.

  8. Q8 · Number System

    How many natural numbers less than 100 are divisible by both 3 and 4?

    • A. 6
    • B. 7
    • C. 8
    • D. 9
    Answer and solution

    Answer: C

    Numbers divisible by both 3 and 4 must be divisible by LCM(3,4) = 12. Numbers less than 100 divisible by 12: 12, 24, 36, 48, 60, 72, 84, 96. Total = 8 numbers.

  9. Q9 · Percentage

    A number is increased by 20% and then decreased by 20%. What is the net percentage change?

    • A. No change
    • B. 2% increase
    • C. 4% decrease
    • D. 4% increase
    Answer and solution

    Answer: C

    Net change = -[(20 × 20)/100] = -4%. Hence, there is a 4% decrease.

  10. Q10 · Algebra

    If x + 1/x = 5, then what is the value of x² + 1/x²?

    • A. 21
    • B. 23
    • C. 25
    • D. 27
    Answer and solution

    Answer: B

    Squaring both sides: (x + 1/x)² = 25, so x² + 2 + 1/x² = 25. Therefore x² + 1/x² = 23.
