Reasoning PYQs

Given equation: 8 + 6 ÷ 51 – 17 × 13 = ?

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

8 + 6 ÷ 51 – 17 × 13 = ? ⇒ 8 × 6 - 51 ÷ 17 + 13 = ?

⇒ 8 × 6 - 51 ÷ 17 + 13 = ?

⇒ 8 × 6 - 3 + 13 = ?

⇒ 48 + 13 - 3 = ?

⇒ 61 - 3 = ?

⇒ 58 = ?

Hence, "Option 2" is the correct answer.

The logic followed here is:

8-17-35

2 × (17 - 8) = 35 - 17

2 × 9 = 18

18 = 18 (LHS = RHS) 

And,

23-47-95

2 × (47 - 23) = 95 - 47

2 × 24 = 48

48 = 48 (LHS = RHS) 

So, checking each option one by one:

Option 1) 9-20-41

2 × (20 - 9) = 41 - 20

2 × 11 = 21

22 ≠ 21 (LHS ≠ RHS)

Option 2) 12-25-51

2 × (25 - 12) = 51 - 25

2 × 13 = 26

26 = 26 (LHS = RHS)

Option 3) 13-29-55

2 × (29 - 13) = 55 - 29

2 × 16 = 26

32 ≠ 26 (LHS ≠ RHS)

Option 4) 16-32-62

2 × **(**32 - 16) = 62 - 32

2 × 16 = 30

32 ≠ 30 (LHS ≠ RHS)

Thus, out of all the options, '12-25-51' follows the same logic as given.

Hence, "Option 2" is the correct answer.

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

Conclusions:

(I) All apples are lemons → Follow (As all apples are mangoes and all mangoes are lemons. As wholes apples comes in mangoes which whole comes in lemons, therefore it is true.)

(II) All mangoes are kiwis → Follow (As all mangoes are lemons and all lemons are kiwis. As wholes mangoes comes in lemons which whole comes in kiwis, therefore it is true.)

∴ Here, Both conclusions I and II follow.

Hence, "Option 4" is the correct answer.

The logic followed here is:

Option 1) 90 – 144

90 × 1.6 = 144

144 = 144 (LHS = RHS)

Option 2) 75 – 120

75 × 1.6 = 120

120 = 120 (LHS = RHS)

Option 3) 45 – 70

45 × 1.6 = 70

72 ≠ 70 (LHS ≠ RHS)

Option 4) 65 – 104

65 × 1.6 = 104

104 = 104 (LHS = RHS)

Thus, out of all the options, '45 – 70' is the odd one out.

Hence, "Option 3" is the correct answer.

The logic followed here is:

(34, 15, 64)

34 + 15 × 2 = 64

34 + 30 = 64

64 = 64 (LHS = RHS)

And,

(29, 17, 63)

29 + 17 × 2 = 63

29 + 34 = 63

63 = 63 (LHS = RHS)

Option 1) (44, 32, 98)

44 + 32 × 2 = 98

44 + 64 = 98

108 ≠ 98 (LHS ≠ RHS)

Option 2) (31, 23, 54)

31 + 25 × 2 = 54

31 + 50 = 54

81 ≠ 54 (LHS ≠ RHS)

Option 3) (25, 14, 53)

25 + 14 × 2 = 53

25 + 28 = 53

53 = 53 (LHS = RHS)

Option 4) (24, 28, 76)

24 + 28 × 2 = 76

24 + 56 = 76

70 ≠ 76 (LHS ≠ RHS)

Thus, out of all the options, '(25, 14, 53)' follows the same logic as given.

Hence, "Option 3" is the correct answer.

The logic followed here is:

1. All elements shift in the anticlockwise direction.

2. Elements shifts by skipping parts i.e. 0, 1, 2, and 3 parts.

Thus, the final series is:

Hence. "Option 4" is the correct answer.

The logic followed here is:

​

Hence, "Option 3" is the correct answer.

The logic followed here is:

​'BUZZY' is coded as '10'

Number of letter in 'BUZZY' → 5 × 2 = 10

And,

'KING' is coded as '8'

Number of letter in 'KING' → 4 × 2 = 8

Similarly,

'ABROAD' is coded as

Number of letter in 'ABROAD' → 6 × 2 = 12

Hence, "Option 4" is the correct answer.

The logic followed here is:

Logic: 1^st number - 83 = 2^nd number.

Now,

for, 186 : 103

→ 186 - 83 = 103,

for, 156 : 73

→ 156 - 83 = 73,

Similarly, for 95 : 12

→ 95 - 83 = 12.

Hence, "Option 4" is the correct answer.

The logic followed here is:

Hence, "Option 2" is the correct answer.

The logic followed here is:

1. First box series:

First row corner elements interchange positions.

First two elements of third row and center element shift anticlockwise.

The rest of the elements shift anticlockwise. 

2. Second box series:

Third column elements shift to the corner opposite sides.

Second column elements shift anticlockwise.

First column elements shift to the corner opposite sides diagonally.

Top left corner element is replaced by new element.

Thus, the final series is:

Hence. "Option 1" is the correct answer.

Given equation: 41 − 54 × 6 ÷ 9 + 7 = ?

According to the question, after '+' and '−' are interchanged and '×' and '÷' are interchanged:

41 − 54 × 6 ÷ 9 + 7 = ? ⇒ 41 + 54 ÷ 6 × 9 - 7 = ?

⇒ 41 + 54 ÷ 6 × 9 - 7 = ?

⇒ 41 + 9 × 9 - 7 = ?

⇒ 41 + 81 - 7 = ?

⇒ 122 - 7 = ?

⇒ 115 = ?

Hence, "Option 4" is the correct answer.

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

Conclusions:

(I) Some pins are pens→ Does not follow (As all pens are pages and some pages are pins. So it is possible but not definite.)

(II) Some boards are pages → Does not follow (As some pages are pins and some pins are boards. So it is possible but not definite.)

(III) Some pens are boards → Does not follow (As all pens are pages, some pages are pins and some pins are boards. So it is possible but not definite.)

∴ Here, None of the conclusions follow.

Hence, "Option 2" is the correct answer.

Decoding symbols:

Given: P − Q + R ÷ S × T

P − Q → P is the son of Q.

Q + R → Q is the wife of R.

R ÷ S → R is the father of S.

S × T → S is the husband of T.

Thus, P is T's husband’s brother or brother-in-law

Hence, the correct answer is "Option 3"

The logic followed here is:

‘Lavish’ is antonym of ‘Austere’.

Similarly,

Hence, "Option 2" is the correct answer.

For find the opposite surface of '1', we need to compare the common surface in the given dices,

Now,

From the given Dice,

 

→ 6 is the common surface in both Dice, and 2, 3, 4,and 5 are the adjacent surfaces, so the remaining surface '1' is the opposite surface of '6'.

Here, '6' is opposite to the face containing '1'.

Hence, the correct answer is "Option 1".

The logic followed here is:

TRAINER : VTCIQHU

And,

RADIANT : TCFIDQW

Similarly,
