RRB ALP (Assistant Loco Pilot) General Intelligence & Reasoning (CBT Stage 1 & Stage 2 Part A) Syllabus

If + means ×, × means -, - means ÷, and ÷ means +, evaluate 6 + 2 - 4 ÷ 3.

12.75. Substitute: 6 × 2 ÷ 4 + 3 = (12 ÷ 4) + 3 = 3 + 3 = ... wait recompute: 6×2=12, 12÷4=3, 3+3=6. Answer is 6.

What is the BODMAS rule used to simplify expressions in Mathematical Operations?

Brackets first, then Of/Orders, then Division and Multiplication (left to right), then Addition and Subtraction (left to right).

What is the focus of Decision Making questions in reasoning?

Applying a given set of conditions/eligibility criteria to a case and deciding the correct course of action (select, reject, refer to higher authority, etc.).

What is Logical Sequencing of words?

Arranging given words in a meaningful order — such as by chronology, size, process steps, or dictionary order (e.g., Seed, Plant, Flower, Fruit).

Arrange logically: 1.Lock 2.Door 3.Key 4.Room 5.Switch on light. What is the correct sequence?

3,1,2,4,5 — Key, Lock (open it), Door, Room, Switch on light: the logical action sequence to enter a room.

What is a Mirror Image?

The lateral (left-right) reversal of an object as seen in a vertical mirror; left becomes right and right becomes left, while top/bottom stay the same.

What is a Water Image (water reflection)?

The vertical (up-down) inversion of an object as seen reflected in water; top becomes bottom and bottom becomes top, while left/right stay the same.

Which letters look the same in their mirror image?

Vertically symmetric letters: A, H, I, M, O, T, U, V, W, X, Y remain unchanged in a mirror image.

Which letters look the same in their water image?

Horizontally symmetric letters: B, C, D, E, H, I, K, O, X remain unchanged in a water image.

In Figure Series, what should you track to find the next figure?

Changes in rotation (direction/angle), number of elements, shading, position, and addition/removal of components from one figure to the next.

What is Pattern Completion (figure matrix) testing?

Detecting the rule governing a grid/matrix or partial figure and selecting the option that correctly completes the missing part following that rule.

In Paper Folding and Cutting, how are holes positioned after unfolding?

Each cut/hole is reflected across every fold line; one fold doubles the holes symmetrically, two folds quadruple them, mirrored about the fold axes.

In a paper folding problem, if a paper is folded once and a hole is punched, how many holes appear when unfolded?

Two holes — symmetric about the fold line (the single punch passes through both layers).

What is an Embedded (Hidden) Figure question?

Finding a given simple figure concealed within a more complex figure, in the same size, orientation, and proportion, without rotation.

What is the key constraint when locating an embedded figure?

The hidden figure must appear in exactly the same shape and orientation (not rotated or resized) as the target figure.

In Direction Sense, what are the four cardinal and four ordinal directions?

Cardinals: North, South, East, West. Ordinals: North-East, North-West, South-East, South-West (the diagonals between cardinals).

In Direction Sense, if you face North and turn right, which direction do you face?

East. A right (clockwise) turn from North leads to East; another right turn leads to South.

In Direction Sense, which formula gives the shortest distance between start and end points?

The Pythagoras theorem: shortest distance = √(horizontal displacement² + vertical displacement²).

A man walks 3 km North, then 4 km East. How far is he from the start?

5 km. By Pythagoras: √(3² + 4²) = √(9+16) = √25 = 5 km.

What are the two main types of Seating Arrangement problems?

Linear arrangement (people in a row/rows) and Circular arrangement (people around a table, facing centre or outward).

In a circular seating arrangement facing the centre, where is a person's right hand directed?

Toward their anticlockwise neighbour; left hand points to the clockwise neighbour (opposite of when facing outward).

What is the first step in solving a Puzzle (e.g., scheduling or floor puzzle)?

Read all clues, separate definite (direct) information from conditional clues, build a table/diagram, and fill in fixed positions first.

How many faces, edges, and vertices does a cube have?

A cube has 6 faces, 12 edges, and 8 vertices (corners).

In a standard die, what is the sum of numbers on opposite faces?

7. Opposite faces total 7: 1-6, 2-5, and 3-4 are the opposite pairs.

When a 3-cm painted cube is cut into 1-cm cubes, how many small cubes have exactly 3 painted faces?

8 — only the corner cubes have three painted faces (a cube always has 8 corners regardless of size).

When a painted cube of side n is cut into unit cubes, how many have no painted face?

(n-2)³ — the inner core cubes that were never on the surface have zero painted faces.

What does a Data Sufficiency question ask you to determine?

Whether the given statements provide enough information to answer the question — NOT to actually compute the final answer.

In Data Sufficiency, what are the standard answer choices?

Whether statement I alone, II alone, either alone, both together, or neither is sufficient to answer the question.

What is Analytical Interpretation of Data (Data Interpretation)?

Reading tables, bar/line graphs, or pie charts and computing values like totals, averages, percentages, ratios, and differences from the data.

In a pie chart, how many degrees represent the whole and how do you find a sector's value?

The whole circle = 360°; a sector's percentage = (sector angle ÷ 360) × 100, and its value = that percentage of the total quantity.

What do Similarities and Differences questions test?

Spotting common features (similarities) among items and the distinguishing feature (difference) — used to group alike items or pick the dissimilar one.
