Reasoning PYQs

Shortcut Trick

Condition to check: Odd Number → Even Number → Even Number

Instead of checking every single number, directly scan the series for two consecutive even numbers.

The only consecutive even numbers in the entire series are 4 and 6 near the end.

Check the number before 4: It is 3 (an Odd number).

Thus, the triplet 3, 4, 6 is the only one that perfectly satisfies the required condition.

∴ The correct answer is 1.

Alternate Method

Given Series:

9 6 9 4 7 8 9 9 1 6 7 3 6 5 9 7 4 7 1 7 7 8 3 4 6 9 3

Condition to be fulfilled:

⇒ Odd Number → Even Number → Even Number

Let us identify all the even numbers in the series from left to right and check their adjacent numbers:

⇒ 9, 6, 9 → Preceded by Odd, Followed by Odd ×

⇒ 9, 4, 7 → Preceded by Odd, Followed by Odd ×

⇒ 7, 8, 9 → Preceded by Odd, Followed by Odd ×

⇒ 1, 6, 7 → Preceded by Odd, Followed by Odd ×

⇒ 3, 6, 5 → Preceded by Odd, Followed by Odd ×

⇒ 7, 4, 7 → Preceded by Odd, Followed by Odd ×

⇒ 7, 8, 3 → Preceded by Odd, Followed by Odd ×

⇒ 3, 4, 6 → Preceded by Odd, Followed by Even ✔

⇒ 4, 6, 9 → Preceded by Even, Followed by Odd ×

⇒ Clearly, there is only one such even number (4) which is immediately preceded by an odd number and immediately followed by an even number.

∴ The correct answer is 1.

Additional Information

Preceded By

In any reasoning sequence, if an element X is 'preceded by' Y, it means Y comes immediately before X in the series (i.e., Y → X).

Followed By

If an element X is 'followed by' Z, it means Z comes immediately after X in the sequence (i.e., X → Z).

Odd and Even Numbers

An even number is an integer perfectly divisible by 2 (e.g., 2, 4, 6, 8), while an odd number leaves a remainder of 1 when divided by 2 (e.g., 1, 3, 5, 7, 9).

Given

Statements:

All wheels are cars.

All cars are trucks.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some trucks are cars - Follows  (Since all cars are inside trucks, at least some trucks are cars).

II. All wheels are trucks - Follows  (All wheels are cars and all cars are trucks, therefore all wheels are trucks).

So, both conclusions I and II follow.

Hence, the correct answer is Option 1.

The logic followed here is:

For, GIMJ is related to LNRO

For, QSWT is related to VXBY

Now, applying the same logic for TVZW

So, TVZW → YAEB

Hence, the correct answer is "Option 4".

Given: Mr. Memi is 34^th from the left and Mr. Zzz is 9^th from the right.

Total number of persons = 104

Convert Mr. Zzz’s position from right into left:

Position from left = (Total + 1) − Position from right

= (104 + 1) − 9

= 96^th

Now, positions:

Mr. Memi = 34^th from left

Mr. Zzz = 96^th from left

Number of persons between them = (96 − 34) − 1

= 62 − 1

= 61

Hence, the correct answer is Option 1.

The logic followed here is:

So, the next term = HVO

Hence, the correct answer is Option 3.

The logic followed here is:

For, PLI − MIF

For, VRO − SOL

Now, applying the same logic for FBY − CYV

So, FBY − CYV follows the same pattern correctly.

Hence, the correct answer is "Option 4".

The logic followed here is:

thus, "6" will replace the question mark in the given series.

Hence, the correct option is "Option 2"

The logic followed here is:

Given:

‘pig peak salad’ is coded as ‘aq ym lq’

‘lemon salad grape’ is coded as ‘wq cv ym’

So, salad → ym

Hence, the correct answer is Option 1.

Given: Z is 61^st from the right end, and total number of students is 97.

Z’s position from left = (97 − 61) + 1 = 37^th

G is 28^th to the left of Z, so:

G’s position from left = 37 − 28 = 9^th

Therefore, G’s position from the left end is 9^th.

Hence, the correct answer is Option 1.

Given:

Kavya walks 100 metres North.

She turns right → 40 metres East.

She turns right → 30 metres South.

She turns right → 40 metres West.

So, she is 70 metres away from her original position.

Hence, the correct answer is Option 4.

Family Chart:

Decoding the Symbols:

Given: L + O # V x E @ R

It means: L is the son of O, O is the sister of V, V is the wife of E, and E is the father of R.

 

So, L is the son of R’s mother’s sister.

Hence, the correct answer is Option 2.

The logic followed here is:

Given:

‘true friends stay’ is coded as ‘eg nu ko’ 

 ‘stay close always’ is coded as ‘bs eg xv’

So, stay → eg

Hence, the correct answer is Option 4.

Given: (Left) 6 4 7 8 5 2 9 5 5 2 2 4 9 8 7 2 3 7 9 5 6 (Right)

Now,

Odd numbers, which are immediately preceded by an even number and also immediately followed by an even number.

So, Needed pattern is: Even Number - Odd Number - Even Number

(Left) 6 4 7 8 5 2 9 5 5 2 2 4 9 8 7 2 3 7 9 5 6 (Right)

So, total valid odd numbers = 4

Hence, the correct answer is Option 3.

The logic followed here is:

thus, "47" will replace the question mark in the given series.

Hence, the correct option is "Option 1".

The logic followed here is based on the alphabetical position pattern:

Option 1: UVQ

Option 2: SRM

Option 3: EFA

Option 4: NOJ

Thus, SRM does not follow the pattern.

Hence, the correct answer is Option 4.

The logic followed here is:

Logic: (1^st number + 2^nd number) + 11 = 3^rd number

For, (5, 12, 28)

⇒ 5 + 12 = 17

⇒ 17 + 11 = 28

For, (8, 15, 34)

⇒ 8 + 15 = 23

⇒ 23 + 11 = 34

Now, checking the options using the same pattern:

Option 1) (23, 30, 64)

⇒ 23 + 30 = 53

⇒ 53 + 11 = 64

Option 2) (21, 14, 32)

⇒ 21 + 14 = 35

⇒ 35 + 11 = 46 ≠ 32

Option 3) (19, 12, 28)

⇒ 19 + 12 = 31

⇒ 31 + 11 = 42 ≠ 28

Option 4) (7, 14, 24)

⇒ 7 + 14 = 21

⇒ 21 + 11 = 32 ≠ 24

Hence, the correct answer is Option 1.

The logic followed here is based on the alphabetical sequence pattern:

Option 1: XY – ZA

Option 2: QR – ST

Option 3: NO – PQ

Option 4: LM – MQ

Thus, LM – MQ does not follow the continuous alphabetical sequence pattern.

Hence, the odd one out is Option 4.

Given: S, I, Q, H, R and G are sitting around a circular table facing the centre.

I sits to the immediate right of S.

Only three people sit between I and Q when counted from the left of I.

R sits to the immediate right of H.

So, there is 1 person between G and H from the left of H.

Hence, the correct answer is "Option 3".

The logic followed here is:

For, BFIF is related to IMPM

For, PTWT is related to WADA

Now, applying the same logic for CGJG

So, CGJG → JNQN

Hence, the correct answer is "Option 1".

Given number: 2436795

Logic:

Add 2 to each even digit

Subtract 3 from each odd digit

Original number: 2 4 3 6 7 9 5

New number: 4 6 0 8 4 6 2

Greatest digit = 8

Smallest digit = 0

Sum = 8 + 0 = 8

Hence, the correct answer is Option 3.
