Q1. A rectangular piece of paper, 20 cm by 16 cm, is folded such that the bottom edge aligns perfectly with the top edge. The paper is then folded again such that the left edge aligns perfectly with the right edge. What is the perimeter of the resulting shape?

36 cm 32 cm 28 cm 24 cm

Q2. A rectangular paper is folded in half vertically. Then it is folded in half horizontally. If a small triangle is cut from the middle of one of the folded edges, how many triangular cutouts will be visible when unfolded?

1 2 3 4

Q3. A triangular paper (isosceles right triangle) is folded by bringing the vertex with the right angle to the midpoint of the hypotenuse. If a single straight cut is made through the midpoint of the hypotenuse, perpendicular to the hypotenuse, how many pieces will the unfolded paper have?

2 3 4 5

Q4. A square paper is folded such that its vertices meet at the center. This process is repeated twice. If a single cut is made from the center to one of the original edges, how many pieces will the unfolded paper have?

4 8 12 16

Q5. What is the next term in the series: 3, 6, 9, 12, 15, ?

16 17 18 19

Q6. Find the next term in the series: 4, 16, 36, 64, 100, ?

121 144 169 81

Q7. Paper cutting can be used to create decorative patterns. This art is often called?

Origami Calligraphy Kirigami Papermaking

Q8. What is the next number in the sequence: 5, 10, 15, 20, 25, ?

30 35 28 32

Q9. Consider a rule designed to ensure the secure interlocking of rolling stock components. If the system detects that a train's coupling mechanism is reported as 'secured', but subsequent diagnostic checks reveal that the locking pins are not fully engaged and there is a minor but measurable play in the connection, what is the most likely rule violation scenario?

A transient sensor error. A misinterpretation of the coupling status by the diagnostic software. A mechanical failure in the locking mechanism or a flaw in the sensor feedback loop. A minor vibration during diagnostics.

Q10. What is the primary goal of rule detection in RRB NTPC exams?

To identify correct answers To identify patterns and relationships in data To create new rules To break existing rules

Q11. Identify the relationship: Vector : Magnitude and Direction :: Scalar : ?

Magnitude Only Direction Only Neither Magnitude nor Direction Vector Quantity

Q12. What is the next number in the sequence: $2, 3, 5, 8, 13, 21, ...$?

34 33 32 35

Q13. What is the common term for blurring or sharpening an image using a kernel?

Image morphing Image filtering Image stitching Image warping

Q14. Consider the series: 1, 4, 9, 16, 25. What is the rule?

Adding 3 Multiplying by 4 Squaring the position of the number (1^2, 2^2, 3^2, ...) Subtracting 7

Q15. What is the missing number in the series: 10, 20, 30, ?, 50, 60

35 40 45 55

Q16. Which diagram illustrates the relationship between 'Instruments', 'Guitars', and 'Pianos'?

One circle inside another, with a third circle separate. Three overlapping circles. Two separate circles inside a larger circle. Three separate circles.

Q17. Find the missing term in the series: $3, 7, 15, 31, 63, x$.

127 126 128 125

Q18. What does a solid white dot (or figure) typically mean on a pedestrian signal?

Do not walk Walk signal Do not cross Wait for the signal

Q19. A square paper is folded in half diagonally. Then the resulting triangle is folded in half by bringing the base to the apex. If a small cut is made from the midpoint of the base of the folded shape, how many cuts will be visible when unfolded?

1 2 3 4

Q20. A rectangular paper is folded in half along its diagonal. If the paper is then unfolded, what is the angle formed by the fold line and one of the sides of the rectangle?

45 degrees Depends on the dimensions of the rectangle 90 degrees 60 degrees
