Reasoning PYQs

The logic followed here is:

Option 1) 335 - 119

335 - 119 = 216

216 = 216 (LHS = RHS)

Option 2) 358 - 152

358 - 152 = 206

206 ≠ 216 (LHS ≠ RHS)

Option 3) 317 - 101

317 - 101 = 216

216 = 216 (LHS = RHS)

Option 4) 308 - 92

308 - 92 = 216

216 = 216 (LHS = RHS)

Thus, out of all the options, '358 - 152' is the odd one out.

Hence, "Option 2" is the correct answer.

The logic followed here is: Multiply the number by 11.

19 is related to 209 → 19 × 11 = 209

27 is related to 297 → 27 × 11 = 297

Similarly, 61 is related: → 61 × 11 = 671

Hence, the correct answer is "671".

The logic followed here is:

1. All the elements shift clockwise including the center element.

Thus, the final series is:

Hence, "Option 2" is the correct answer.

Given: 4515 × 5 − 431 ÷ 3 + 821 = ?

According to the question, after ‘+’ and ‘–‘ are interchanged and ‘x’ and ‘÷’ are interchanged:

4515 × 5 − 431 ÷ 3 + 821 = ? ⇒ 4515 ÷ 5 + 431 × 3 – 821 = ?

⇒ 4515 ÷ 5 + 431 × 3 – 821 = ?

⇒ 903 + 431 × 3 – 821 = ?

⇒ 903 + 1293 – 821 = ?

⇒ 2196 – 821 = ?

⇒ 1375 = ?

Hence, "Option 3" is the correct answer.

The logic followed here is :-

From the given three different cubes the adjacent sides are as shown below :

As 25 is common on both the dices I and III, it is clear that 21, 23, 22, and 24 are adjacent to it, and the remaining i.e. 26 will be opposite to it.

Opposite pairs:

23 → 22

21 → 24

25 → 26

So, the opposite side of "24" will be side "21".

Hence, the correct answer is "Option 2".

The logic followed here is: The difference between the numbers in both pairs is 121.

First, let's find the difference between the numbers in each pair:

For the pair 31 and 152:

152 − 31 = 121

For the pair 47 and 168:

168 − 47 = 121

Now, we need to find the number that is related to 66 following the same logic. We do this by adding 121 to 66:

66 + 121 = 187

Thus, the number that is related to 66 is 187.

Hence, the correct answer is "187".

The logic followed here is: 2^nd number - 1^st number = 64.

(149, 213) → 213 - 149 = 64

(168, 232) → 232 - 168 = 64,

Let's check options one by one.

Option 1)  (162, 222) → 222 - 162 = 60 ≠ 64

Option 2)  (137, 211) → 211 - 137 = 74 ≠ 64

Option 3) (153, 217) → 217 - 153 = 64

Option 4)  (144, 198) → 198 - 144 = 54 ≠ 64

Hence, the correct answer is "(153, 217)".

The logic followed here is: Each of the other word pairs correctly matches a polygon with the number of its sides.

• Triangle has 3 sides
• Pentagon has 5 sides
• Square has 4 sides

Whenever, a Hexagon has 6 sides, not 8.

Therefore, "Hexagon - 8 sides" is the word pair that does not belong to the group.

Hence, the correct answer is "Hexagon - 8 sides".

The number of triangles in the given figure is shown below:

1) Total triangles = [Number of parts × (1 + Number of parts)] ÷ 2

= [2 × (1 + 2)] ÷ 2

= [2 × 3] ÷ 2

= 6 ÷ 2

= 3

As there are 3 same types of triangles, therefore total number of triangles will be (3 × 3) = 9 

2. As marked there are total 12 triangles.

Thus, there are total (9 + 12) = 21 triangles.

Hence, "Option 1" is the correct answer.

Decoding symbols:

So,

i. A + K / J - P = D → A is mother of K who is the wife of J who is the father of P who is the brother of D.

Here, A is the mother of K.

ii. J % P = K + A = D → J is sister of P who is the brother of K who is the mother of A who is the brother of D.

Here, A is the son of k.

iii. K + A / P - D % J → K is mother of A who is the wife of P who is the father of D who is the sister of J.

Here, A is the daughter of K.

iv. D + K = A / P – J → D is mother of K who is the brother of A who is the wife of P who is the father of J.

Here, A is the sister of K.

Hence, the correct answer is "Option 3"$

The number of triangles in the given figure is shown below:

Thus, as marked there are a total of 4 triangles.

Hence, "Option 3" is the correct answer.

Given: 4 ÷ 6 + 91 × 7 − 5 = ?

According to the question, after ‘+’ and ‘–‘ are interchanged and ‘x’ and ‘÷’ are interchanged:

4 ÷ 6 + 91 × 7 − 5 = ? ⇒ 4 × 6 – 91 ÷ 7 + 5 = ?

⇒ 4 × 6 – 91 ÷ 7 + 5 = ?

⇒ 4 × 6 – 13 + 5 = ?

⇒ 24 + 5 – 13 = ?

⇒ 29 – 13 = ?

⇒ 16 = ?

Hence, "Option 2" is the correct answer.

The logic followed here is:

Option 1) EJ - OT

Option 2) PF - OI

Option 3) KP - UZ

Option 4) CH - MR

Thus, out of al the options 'PF - OI' is the odd one out.

Hence, "Option 2" is the correct answer.

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

Conclusions:

I. Some brown are fans → Follow (As all fans are brown. As whole fans comes in brown, therefore it is true.)

II. Some chairs are brown → Follow (As some brown are chairs. As brown has some part common with chairs, therefore it is true.)

III. No chair is plastic → Does not follow (As some chairs are plastic. As no statements restricts chairs from being plastic, therefore it is false.)

∴ Here, Only I and II conclusion follow.

Hence, "Option 3" is the correct answer.

Given: 1604 × 4 – 525 ÷ 5 + 73 = ?

According to the question, after ‘+’ and ‘–‘ are interchanged and ‘x’ and ‘÷’ are interchanged:

1604 × 4 – 525 ÷ 5 + 73 = ? ⇒ 1604 ÷ 4 + 525 × 5 – 73 = ?

⇒ 1604 ÷ 4 + 525 × 5 – 73 = ?

⇒ 401 + 525 × 5 – 73 = ?

⇒ 401 + 2625 – 73 = ?

⇒ 3026 – 73 = ?

⇒ 2953 = ?

Hence, "Option 3" is the correct answer.

Given word: 'SYSTEM'

After arranged in alphabetical order:

 

Now,

there is One alphabet "S" will remain unchanged if each of the letters in the word 'SYSTEM' is arranged in English alphabetical order.

And, 'Five' letters will change.

Hence, the correct answer is "Option 1".

The logic followed here is:

Hence, "Option 4" is the correct answer.

The logic followed here is:

Hence, "Option 2" is the correct answer.

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

Conclusions:

I. No animal is a mountain → Does not follow (As no river is a mountain and some rivers are animals. As no direct relation is given between animals and mountains, therefore it is false.)

II. No river is a bird → Does not follow (As no river is a mountain and some birds are mountains. As no direct relation is given between river and bird, therefore it is false.)

∴ Here, Neither conclusion (I) nor (II) follows.

Hence, "Option 2" is the correct answer.

The logic followed here is:

1. All the elements shift clockwise excluding the center element.

2. Center element and left bottom corner is flipped vertically subsequently.

Thus, the final series is:

Hence, "Option 3" is the correct answer.
