Reasoning PYQs

Given:

Statement: A recent study shows rising childhood obesity.

Courses of Action:

I. Ban all junk food advertisements - False (Because completely banning all junk food advertisements is an extreme measure. The statement alone does not justify such a blanket ban.)

II. Make physical activity mandatory in schools - True (Because encouraging regular physical activity is a practical and effective step to help address rising childhood obesity.)

So, only Course of Action II follows.

Hence, the correct answer is "Only Course of Action 2 follows."

Given Conditions:

Floors 1 (lowest) to 6 (highest)

C = 1^st floor

E lives on even floor

2 floors between E and C

1 floor between E and F

F not immediately above C

2 people between A and D

D not on odd floor

Step 1: Fix C

Step 2: Place E (2 floors between E and C)

Possible even floors: 2, 4, 6

Check 2 floors gap from floor 1:

If E = 2 → gap = 0 

If E = 4 → gap = 2 

If E = 6 → gap = 4 

So, E must be on 4^th floor.

Step 3: Place F (1 floor between E and F)

From 4^th floor, F can be:

• 2^nd floor

• 6^th floor

Case 1: F = 2^nd floor

Case 2: F = 6^th floor

But F cannot be immediately above C.

2^nd floor is immediately above 1^st floor 

So Case 1 rejected.

Step 4: Place D (not on odd floor)

Even floors available: 2 (4 & 6 taken)

So D = 2^nd floor.

Step 5: 2 people between A and D

D is on 2^nd floor.

To have 2 people between → A must be on 5^th floor.

Remaining floor: 3^rd floor → B

B = 3^rd floor

2 floors below → 1^st floor → C

Hence, the correct option is Option 4.

The least possible Venn diagram for the given statements is as shown below

Conclusions:

I. No orange is blue. → Follow (As no apple is blue and all oranges are apples. So whole oranges comes in apple which cannot be blue, therefore it is true.)

II. Some apples are oranges → Follow (A all oranges are apples. So whole oranges comes in apple, therefore it is true.)

Thus, both I and II follow.

Hence, the correct answer is “Option 3”.

The least possible Venn diagram for the given statements is as shown below

Conclusions:

I. Some bags are not scales → Does not follow (As all bags are pens, some pens are not pencils and no pencil is a scale. As no direct relation is given between bags and scale, therefore it is possible but noy definite.)

II. All scales are pencils → Does not follow (As no pencil is a scale. As direct relation is given between pencil and scale, therefore it is false.)

Thus, Neither I nor II follows.

Hence, the correct answer is “Option 4”.

Given Cities

Paris

Rome

Berlin

Madrid

Vienna

Brussels

Alexandria

Amsterdam

Observation:

Paris → Capital of France 

Rome → Capital of Italy 

Berlin → Capital of Germany 

Madrid → Capital of Spain 

Vienna → Capital of Austria 

Brussels → Capital of Belgium 

Amsterdam → Capital of Netherlands 

Alexandria → Not a capital city (Major city in Egypt) 

All others are capital cities of European countries, but Alexandria is not a capital city.

Hence, the correct answer is Option 3.

The logic followed here: 

Convert letters to positions

A = 1

C = 3

F = 6

J = 10

Find the pattern

3 − 1 = 2

6 − 3 = 3

10 − 6 = 4

The pattern is increasing by +2, +3, +4

Next increase = +5

10 + 5 = 15

15^th letter = O

Hence, the correct answer is Option 4.

Given Series

100, 50, 25, ___

Observe the pattern

50 = 100 ÷ 2

25 = 50 ÷ 2

Each number is divided by 2.

Find the next number

25 ÷ 2 = 12.5

Hence, the correct answer is Option 2.

Given

CLEAN → BKDZM

Observe the pattern

 

 

Each letter is shifted one step backward in the alphabet.

GLASS

So, GLASS → FKZRR

Hence, the correct answer is Option 1.

The logic followed here

4 − 2 = 2

7 − 4 = 3

11 − 7 = 4

16 − 11 = 5

The differences are increasing consecutively:

+2, +3, +4, +5

Next difference

Next increase = +6

16 + 6 = 22

Hence, the correct answer is Option 1.

The logic followed here 

Forward (+1): 3 → 4 → 5

Backward (−1): 24 → 23 → 22

next letter position = 5 → E

Observe the number pattern

3, 24, 4, 23

Forward series: 3 → 4 → 5

Backward series: 24 → 23 → 22

Next number = 5

Hence, the correct answer is Option 2.

Given:

A number is coded as three digits representing the remainders when divided by 3, 7 and 11 respectively.

We need a number whose code is: 2, 2, 2

That means:

Number ÷ 3 → Remainder 2

Number ÷ 7 → Remainder 2

Number ÷ 11 → Remainder 2

Check Options

Option 1: 223

223 ÷ 3 = 74 R1

Option 2: 323

323 ÷ 3 = 107 R2 

323 ÷ 7 = 46 R1

Option 3: 233

233 ÷ 3 = 77 R2

233 ÷ 7 = 33 R2

233 ÷ 11 = 21 R2

All remainders are 2.

Option 4: 243

243 ÷ 3 = 81 R0

Hence, the least number is 233.

Hence, the correct answer is Option 3.

Given

Find the relation

100 → 1000

100 = 10²

1000 = 10³

So, the pattern is:

If a number is a perfect square (n²), it is converted to n³.

Apply same logic to 64

64 = 8²

So, 64 → 8³

= 512

Hence, the correct option is Option 3.

Given Situation

Option 1: Respecting the choice without intervention is incomplete because the doctor must first ensure informed understanding.

Option 2: The doctor should counsel the patient, clearly explain the risks and benefits, attempt to address concerns, and properly document the refusal. This follows ethical and legal guidelines.

Option 3: Forcing medication violates patient autonomy (unless the patient lacks decision-making capacity or there is a legal mandate).

Option 4: Ignoring the patient is unprofessional and unethical.

 

Hence, the correct answer is Option 2.

Shortcut Trick

Current ratio (Man:Daughter) = 4 : 1 (Difference = 3 units)

Ratio after 20 years = 2 : 1. Make differences equal: multiply by 3 → 6 : 3

Increase in units = 6 − 4 = 2 units. These 2 units = 20 years.

1 unit = 10 years. Daughter's current age (1 unit) = 10 years.

∴ The correct answer is 10 years.

Alternate Method

Given: Present age ratio = 4:1. Ratio after 20 years = 2:1.

Formula Used: Ratio & Proportion linear equations.

Now After 20 years Daughter: x Man: 4x Daughter: x+20 Man: 4x+20 +20 years

⇒ Let Daughter's age = x and Man's age = 4x.

⇒ After 20 years: (4x + 20) = 2 × (x + 20)

⇒ 4x + 20 = 2x + 40

⇒ 4x − 2x = 40 − 20

⇒ 2x = 20

⇒ x = 10

∴ The correct answer is 10 years.

Additional Information

Concept of Age Difference

The age difference between two people always remains constant throughout their lives. This is a key tool in solving ratio-based age problems.

Ratio Balancing

To solve age ratios quickly, multiply the ratios so that the difference between the parts (Man − Daughter) is identical in both current and future ratios.

Linear Equations in Ages

If "n" years ago is mentioned, subtract n from current age; if "n" years hence/later is mentioned, add n to the current age.

The logic followed here is:

MANGO is written as NZOHQ

Similarly,

APPLE is written as

Hence, the correct answer is "Option 1".

Given Address:

Flat No. 6A, Pearl View, Salt Lake, Kolkata, West Bengal - 700091

 

Option 1

Flat No. 6A, Pearl View, Salt Lake, Kolkata, West Bengal - 700091

Flat Number — Same

Building Name — Same

Area — Same

City — Same

State — Same

PIN Code — Same

Option 2

Flat No. 6A, Pearl View, Salt Lake, Kolkata, Assam - 700091

 State is different

Option 3

Flat No. 6A, Pearl View, Salt Lake, Kolkata, Odisha - 700091

State is different

Option 4

Flat No. 6A, Pearl View, Salt Lake, Kolkata, Bihar - 700091

State is different

 

Hence, the correct answer is Option 1.

Logical arrangement using elimination

⇒ Raipur ≠ 11^th ⇒ Raipur is either 7^th or 9^th

⇒ If Raipur = 9^th ⇒ Bhopal must be 7^th (since Indore after Bhopal)

⇒ Then Indore = 11^th (valid)

⇒ Check all conditions satisfied

⇒ If Raipur = 7^th ⇒ Bhopal must be before Indore

⇒ Possible: Bhopal = 9^th, Indore = 11^th

⇒ But Raipur already 7^th, still valid

⇒ Both cases give Indore = 11^th

∴ Indore seminar was held on 11^th August

The logic is followed here

76 → 80 (+4)

80 → 71 (−9)

71 → 87 (+16)

87 → 62 (−25)

The pattern is

+2², −3², +4², −5²

Next should be:

+6² = +36

62 + 36 = 98

Hence, the correct answer is Option 2.

The logic is followed here

Checking the pattern

9 × 2 + 1 = 19 

19 × 2 + 1 = 39 

39 × 2 + 1 = 79  (But given 78)

79 × 2 + 1 = 159 

159 × 2 + 1 = 319 

Multiply by 2 and add 1.

Hence, the WRONG number is Option 3.

Given:

Find the remainder when 987654321 is divided by 9.

Rule:

A number is divisible by 9 if the sum of its digits is divisible by 9. The remainder when dividing by 9 is the same as the remainder of the sum of its digits divided by 9.

9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45

Divide 45 by 9

45 ÷ 9 = 5 (remainder 0)

Hence, the remainder is Option 3.
