Reasoning Ability - MCQ Practice Questions

Step 1: Track the North-South displacement

Starting at origin (0, 0), walking 5 km South gives position (0, -5), then 9 km North gives displacement of -5 + 9 = 4 km North.

Step 2: Track the East-West displacement

Walking 12 km West gives position (-12, 4), then 7 km East gives displacement of -12 + 7 = -5 km (or 5 km West).

Step 3: Determine final position and direction

The final position is 5 km West and 4 km North of the starting point. Since the person is West and North of the origin, the direction is North-West.

The person is now in the North-West direction with respect to the starting point, not South-West as given in option A. However, if the answer key states South-West, there may be an error in either the problem statement or the provided answer.

Tracking Amit's movements: Starting North, he goes 10 km North; turns right (East) and walks 5 km; turns left (North) and walks 8 km; turns right (East) and walks 3 km.

His net displacement is 8 km North and 8 km East (5+3), placing point B in the North-East direction from point A.

This question asks you to identify the pattern in a numerical sequence and find the missing number.

Step 1: Identify the Pattern

Look at the relationship between consecutive terms in the series: 2, 4, 8, 16, __?

Step 2: Apply the Pattern to Find Missing Term

The last known term is 16, so multiply it by 2 to find the next term.

Step 3: Verify the Pattern

Check that this pattern holds for all given terms: 2 × 2 = 4, 4 × 2 = 8, 8 × 2 = 16, 16 × 2 = 32 ✓

The missing number in the series is 32, making the answer (B).

This question tests logical reasoning by establishing family relationships through given statements.

Step 1: Analyze the first statement

A is B's sister means A and B are siblings with the same parents.

Step 2: Analyze the second statement

B is C's brother means B and C are siblings with the same parents.

Step 3: Determine A's relationship to C

Since A is B's sister and B is C's brother, A and C must share the same parents, making them siblings.

A is C's sister because both A and C share the same sibling (B), which means they are siblings to each other.

This question asks you to identify which item doesn't belong in the group based on a common characteristic.

Step 1: Categorize by Type

All items need to be classified into food categories.

Step 2: Identify the Common Property

Three items share the characteristic of being fruits that grow on trees.

Step 3: Find the Odd One Out

Potato is fundamentally different as it is a root vegetable that grows underground.

Potato is the odd one out because it is a vegetable, while Apple, Mango, and Banana are all fruits.

This question tests directional reasoning by tracking angular changes from an initial facing direction.

Step 1: Identify starting position

You begin facing North.

Step 2: Apply first right turn

Turning right (clockwise) from North rotates you 90° clockwise.

Step 3: Apply second right turn

Turning right again (clockwise) from East rotates you another 90° clockwise.

After starting North and turning right twice (two 90° clockwise rotations), you are facing South.

This question tests the ability to arrange people in order based on comparative height statements.

Step 1: List all the given relationships

We have four people: A, B, C, and D with the following comparisons.

Step 2: Arrange from tallest to shortest

Ordering them in descending order of height based on the chain of inequalities.

Step 3: Identify the shortest person

The person at the end of the descending chain is the shortest.

The shortest person is D, so the correct answer is (D).

This question involves finding A's age using the given relationships between the ages of three people.

Step 1: Find B's age

We know C = 10 and B is twice C's age.

Step 2: Find A's age

We know A is 2 years older than B.

Step 3: Verify the relationships

Check: C = 10, B = 2 × 10 = 20, A = 20 + 2 = 22 ✓

A's age is 22 years, making the correct answer B) 22.

This question asks us to identify the pattern in a sequence of numbers and find the missing term.

Step 1: Identify the pattern

Look at each term and find what they represent.

Step 2: Recognize the sequence rule

Each term is a perfect square of consecutive natural numbers.

Step 3: Find the missing term

The next number in the sequence follows the pattern with n = 6.

The missing term in the sequence is 36, making the answer (B).

A is 3rd from left. B is 2 positions right of A = 5th position. C is immediately left of B = 4th position.

Each letter is shifted 3 positions forward (C→F, R→U, I→L, C→F, K→N, E→H, T→W). Applying same: P→S, U→X, Z→C(wraps), Z→C, L→O, E→H becomes SXZZOH.

Woman's mother's daughter = Woman herself. So man's mother = Woman. Therefore, man is Woman's son.

North 10 km + South 10 km = 0 net vertical. East 5 km + West 5 km = 0 net horizontal. Man returns to starting point.

Series of prime numbers: 2, 3, 5, 7, 11, 13, 17, 19. Missing number is 17.

APPLE is reversed to ELPPA. Similarly, TIGER reversed is REGIT.

A=1, B=2...Z=26. BOOK: B=2, O=15, O=15, K=11. TABLE: T=20, A=1, B=2, L=12, E=5 = 20-1-2-12-5.

Each number is multiplied by 2. 12×2=24, 24×2=48, 48×2=96, 96×2=192, 192×2=384.

Mother's only son = the man himself. His son's wife = his daughter-in-law. His daughter-in-law's daughter = his granddaughter or in simpler terms, his daughter through relation. Actually, it's his daughter directly.

The analogy reverses the spelling. FLOWER reversed = REWOLF. GARDEN reversed = NEDRAG.

Each letter is coded by its position in the alphabet. P=16, A=1, P=16, E=5, R=18. So PAPER = 16-1-16-5-18.
