Reasoning PYQs

Given

Statements:

Some deer are snakes.

All deer are tigers.

Some wolves are deer.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some tigers are not deer - False (Because, All deer are tigers gives some tigers are deer, and the remaining part can be possible only).

II. Some deer are wolves - True (Because, Some wolves are deer gives Some deer are wolves).

III. Some tigers are snakes - True (Because, Those part of Tigers which is Deer is Snakes).

So, Only conclusions II and III follow.

Hence, the correct answer is "Option 2".

The logic followed here is:

Option 1) PSQR

Option 2) JLKM

Option 3) FHGI

Option 4) TVUW

Here, 'PSQR' is odd among the given options.

Hence, the correct answer is "Option 1".

Given

Statements:

Some pinks are black.

Some blue are pink.

The least possible Venn diagram for the given statement is:

Conclusions:

I. All blue are black - False (Because, No definite relation given between Blue and Black, so it can be possible only).

II. All pink are black - False (Because, Some pinks are black, and the remaining part will be possible only).

So, Neither conclusion I nor II follows.

Hence, the correct answer is "Option 2".

Given: Seven friends A, B, C, D, E, F and G are of different weights.

1. Only two people are lighter than G. 

2. Only four people are lighter than A.

3. Only one person is lighter than B.

__ > __ > A > __ > G > B > __

4. E is heavier than C.

5) F is lighter than C.

6. D is heavier than E.

D > E > C > F

After, combining the statements,

D > E > A > C > G > B > F

Here, 'D' is the heaviest among all.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: Numbers are written in reverse order.

Now,

For, [13/17] ∶ [17/13]

⇒ [13/17] reverse [17/13]

For, [33/26] ∶ [26/33]

⇒ [33/26] reverse [26/33]

Similarly, for [23/18] ∶ ? 

⇒ [23/18] reverse [18/23]

Hence, the correct answer is "Option 4".

Given date: 05 April 1234.

Now,

Till 1234 → 1200 + 33

 

⇒ 0 + 41

⇒ 41 odd days.

And, till 5 April.

⇒ 31(Jan) + 28(Feb) + 31(March) + 5(April) = 95 odd days.

Total odd days → 41 + 95 = 136 days = 136/7 = 19 week and 3 odd days.

→ 3 represents Wednesday.

So, 05 April 1234 was Wednesday.

Hence, the correct answer is "Wednesday".

Given: Seven people A, B, C, D, E, F and G are sitting in a straight row, facing north.

1. Only two people sit to the right of E.

2. G has no neighbours on the left.

3) B sits third to the right of G.

4) D is the only neighbour of A.

5) Only two people sit between D and C.

Here, 'B' sits third to the right of G.

Hence, the correct answer is "Option 2".

The correct mirror image of the given figure is:

Hence, the correct answer is "Option 2".

The logic followed here is:

So, 'PU' will replace the question mark in the given series.

Hence, the correct answer is "Option 1".

The logic followed here is:

Logic: 1^st number × 3 = 2^nd number;

2^nd number × 3 = 3^rd number.

Now,

For, (21, 63, 189)

⇒ 21 × 3 = 63

⇒ 63 × 3 = 189.

For, (19, 57, 171)

⇒ 19 × 3 = 57

⇒ 57 × 3 = 171.

Using the same logic, let's evaluate the given options:

1. (34, 102, 136) ⇒ 34 × 3 = 102 but 102 × 3 ≠ 136.
2. (23, 69, 207) ⇒ 23 × 3 = 69 and 69 × 3 = 207.
3. (32, 96, 78) ⇒ 32 × 3 = 96 but 96 × 3 ≠ 78.
4. (24, 48, 96) ⇒ 24 × 3 = 72 ≠ 4.

Hence, the correct answer is "Option 2".

The logic followed here is:

Logic: (1^st number + 3^rd number) ÷ 2 = 2^nd number.

Now,

For (663, 590, 517)

→ (663 + 517) ÷ 2

→ 1180 ÷ 2 = 590.

For (499, 426, 353)

→ (499 + 353) ÷ 2

→ 852 ÷ 2 = 426.

Similarly, for (524, 451, 378)

→ (524 + 378) ÷ 2

→ 902 ÷ 2 = 451.

Hence, the correct answer is "Option 3".

The correct mirror image of the given figure is:

Hence, the correct answer is "Option 1".

Given: P, Q, R, S, T, U and V are seven friends having different heights.

1. R is taller than 4 persons.

__ > __ > R > __ > __ > __ > __

2. Q is taller than R but shorter than P.

P > Q > R > __ > __ > __ > __

3. T is taller than U but shorter than S.

4. U is not the shortest.

P > Q > R > S > T > U > V

So, there are 'two' people are shorter than T.

Hence, the correct answer is "Option 3".

The logic followed here is:

So, '210' will complete the series.

Hence, the correct answer is "Option 2".

Mistake Points We need to find the option which is not similar to the given logic in the question.

The logic followed here is:

Logic: 1^st number × (2^nd number ÷ 3) = 3^rd number.

For, (12, 21, 84)

→ 12 × (21 ÷ 3)

→ 12 × 7 = 84.

Now, checking the options,

Option 1) (14, 21, 98)

→ 14 × (21 ÷ 3)

→ 14 × 7 = 98 → Followed the logic.

Option 2) (14, 18, 84)

→ 14 × (18 ÷ 3)

→ 14 × 6 = 84 → Followed the logic.

Option 3) (16, 15, 80)

→ 16 × (15 ÷ 3)

→ 16 × 5 = 80 → Followed the logic.

Option 4) (24, 18, 96)

→ 24 × (18 ÷ 3)

→ 24 × 6 = 144 ≠ 96 → Does not followed the logic.

Hence, the correct answer is "Option 4".

The logic followed here is:

Option 1) CDXW

Option 2) JQKP

Option 3) FUGT

 

Option 4) HSIR

Here, 'CDXW' is odd among the given options.

Hence, the correct answer is "Option 1".

The logic followed here is:

For, LAMP ∶ BNMQ

For, MOON ∶ PPNO

 

Similarly, for MARS ∶ ?

Hence, the correct answer is "Option 3".

Given equation: 52 + 36 ÷ 9 × 3 − 1 = 210.

BODMAS Table: 

Let's check each option one by one.

Option 1) − and +

Given: 52 + 36 ÷ 9 × 3 − 1 = 210

After interchanging the signs we get;

⇒ 52 - 36 ÷ 9 × 3 + 1 = 210

⇒ 52 - 4 × 3 + 1 = 210

⇒ 52 - 12 + 1 = 210

⇒ 53 - 12 = 210

⇒ 41 ≠ 210

⇒ LHS ≠ RHS

Option 2) × and +

Given: 52 + 36 ÷ 9 × 3 − 1 = 210

After interchanging the signs we get;

⇒ 52 × 36 ÷ 9 + 3 − 1 = 210

⇒ 52 × 4 + 3 − 1 = 210

⇒ 208 + 3 − 1 = 210

⇒ 211 − 1 = 210

⇒ 210 = 210

⇒ LHS = RHS

Option 3) ÷ and ×

Given: 52 + 36 ÷ 9 × 3 − 1 = 210

After interchanging the signs we get;

⇒ 52 + 36 × 9 ÷ 3 − 1 = 210

⇒ 52 + 36 × 3 − 1 = 210

⇒ 52 + 108 − 1 = 210

⇒ 160 − 1 = 210

⇒ 159 ≠ 210

⇒ LHS ≠ RHS

Option 4) ÷ and -

Given: 52 + 36 ÷ 9 × 3 − 1 = 210

After interchanging the signs we get;

⇒ 52 + 36 - 9 × 3 ÷ 1 = 210

⇒ 52 + 36 - 9 × 3 = 210

⇒ 52 + 36 - 27 = 210

⇒ 88 - 27 = 210

⇒ 61 ≠ 210

⇒ LHS ≠ RHS

Hence, the correct answer is "Option 2".

Given: 

Town B is to the north of Town A.

Town C is to the east of Town B.

Town D is to the north of Town C.

Town E is to the west of Town D.

So, Town E is in 'North' direction of Town A.

Hence, the correct answer is "Option 3".

The logic followed here is:

Logic: (1^st number + 1)² + 1^st number = 2^nd  number.

Now,

For 12 ∶ 181

→ (12 + 1)² + 12

→ 132 + 12

→ 169 + 12 = 181.

For 14 ∶ 239

→ (14 + 1)2 + 14

→ 152 + 14

→ 225 + 14 = 239.

Similarly, for 17 ∶ ?

→ (17 + 1)2 + 17

→ 182 + 17

→ 324 + 17 = 341.

Hence, the correct answer is "Option 4".
