Reasoning PYQs

The logic followed here is:

198-297-594

1 + 9 + 8 = 18

2 + 9 + 7 = 18

5 + 9 + 4 = 18

So, checking each option one by one:

Option 1) 442-513-711

4 + 4 + 2 = 10 ≠ 18

5 + 1 + 3 = 9 ≠ 18

7 + 1 + 1 = 9 ≠ 18

Option 2) 488-364-299

4 + 8 + 8 = 20 ≠ 18

3 + 6 + 4 = 13 ≠ 18

2 + 9 + 9 = 20 ≠ 18

Option 3) 125-223-342

1 + 2 + 5 = 8 ≠ 18

2 + 2 + 3 = 7 ≠ 18

3 + 4 + 2 = 9 ≠ 18

Option 4) 369-576-747

3 + 6 + 9 = 18

5 + 7 + 6 = 18

7 + 4 + 7 = 18

Thus, out of all the options, '369-576-747' follows the same logic as given.

Hence, "Option 4" is the correct answer.

Given: 

1) Ravi and Raghu are brothers.

2) Raju is the father of Raghu.

3) Shyam is also the mother's brother of Ravi.

4) Shyam is the brother of Tushar. 

Here, Shyam's is Raju's brother-in-law or wife's brother.

Hence, the correct answer is "Option 2".

The logic followed here is:

Hence, "Option 1" is the correct answer.

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

Conclusions:

1. All dogs are stones → Does not follow (As all stones are chairs and some chairs are dogs. So it is possible but not definite)
2. At least some dogs are chairs → Follow (As some chairs are dogs. As some part of chairs is common with dogs, therefore it is true.)

∴ Here, Only conclusion 2 follows.​

Hence, the correct answer is "Option 2"

Given: K, L, M, W, X, Y and Z scored different marks in an exam.

1) X scored less than only Y.

Y > X > _ > _ > _ > _ > _

2. K scored more than both L and W but less than Y.

3) K scored more than M.

4) Neither L nor M scored the lowest marks.

Case 1) Y > X > K > L/W/M > L/W/M > L/W/M > _

Case 2) Y > X > K > _ > L/M > L/M > W

Case 3) Y > X > K > L/M > _ > L/M > W

Case 4) Y > X > _ > K > L/M > L/M > W

5) Z scored more than L, but less than M.

As, there is no possible position for Z in case 1, 2 and 4, therefore are eliminated.

Case 3) Y > X > K > M > Z > L > W

Thus, according to the final arrangement Z scored the third-lowest marks.

Hence, "Option 1" is the correct answer.

The logic followed here is:

Hence, "Option 3" is the correct answer.

Decoding signs:

Given: 9 × 4 + 5 - 2 = ?

9 × 4 + 5 - 2 = ? ⇒ 9 + 4 - 5 × 2 = ?

⇒ 9 + 4 - 5 × 2 = ?

⇒ 9 + 4 - 10 = ?

⇒ 13 - 10 = ?

⇒ 3 = ?

Hence, "Option 2" is the correct answer.

The logic followed here is:

Hence, "Option 3" is the correct answer.

Given: 4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18

According to the question, if two numbers on the left-hand side are interchanged and two signs on the right-hand side are interchanged:

Option 1) 4 and 6; ÷ and ×

4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18 ⇒ 6 × 3 ÷ 4 + 2 – 8 = 10 + 2 ÷ 3 × 5 – 18

⇒ 6 × 3 ÷ 4 + 2 – 8 = 10 + 2 ÷ 3 × 5 – 18

⇒ 6 × 0.75 + 2 – 8 = 10 + 0.67 × 5 – 18

⇒ 4.5 + 2 – 8 = 10 + 3.35 – 18

⇒ 6.5 - 8 = 13.35 - 18

⇒ -1.5 ≠ -4.65 (LHS ≠ RHS)

Option  2) 2 and 4; + and ×

4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18 ⇒ 2 × 3 ÷ 6 + 4 – 8 = 10 × 2 + 3 ÷ 5 – 18

⇒ 2 × 3 ÷ 6 + 4 – 8 = 10 × 2 + 3 ÷ 5 – 18

⇒ 2 × 2 + 4 – 8 = 10 × 2 + 0.6 – 18

⇒ 4 + 4 – 8 = 20 + 0.6 – 18

⇒ 8 – 8 = 20.06 – 18

⇒ 0 ≠ 2.06 (LHS ≠ RHS)

Option  3) 6 and 8; + and -

4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18 ⇒ 4 × 3 ÷ 8 + 2 – 6 = 10 - 2 × 3 ÷ 5 + 18

⇒ 4 × 3 ÷ 8 + 2 – 6 = 10 - 2 × 3 ÷ 5 + 18

⇒ 4 × 0.375 + 2 – 6 = 10 - 2 × 0.6 + 18

⇒ 1.5 + 2 – 6 = 10 + 18 - 1.2

⇒ 3.5 – 6 = 28 - 1.2

⇒ -2.5 ≠ 26.8 (LHS ≠ RHS)

Option  4) 4 and 8; + and ÷

4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18 ⇒ 8 × 3 ÷ 6 + 2 – 4 = 10 ÷ 2 × 3 + 5 – 18

⇒ 8 × 3 ÷ 6 + 2 – 4 = 10 ÷ 2 × 3 + 5 – 18

⇒ 8 × 0.5 + 2 – 4 = 5 × 3 + 5 – 18

⇒ 4 + 2 – 4 = 15 + 5 – 18

⇒ 6 – 4 = 20 – 18

⇒ 2 = 2 (LHS = RHS)

Hence, "Option 4" is the correct answer.

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

Conclusions:

I. All gems are pebbles → Does not follow (As all stones are pebbles and some stones are gems. So it is possible but not definite)

II. Some pebbles are stones → Follow (As all stones are pebbles. As whole stones comes in pebbles, therefore it is true)

∴ Here, Only conclusion II follows.​

Hence, the correct answer is "Option 4"

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

1. Only 2 people sit to the left of E.

2. G is an immediate neighbour of E.

3) Only 3 people sit between G and F → This Eliminates Case 1(Because, There is no possible position left for F)

4) B sits to the immediate right of F.

5. A sits to the immediate left of D.

So, C will sit at the extreme left end of the row.

Hence, the correct answer is "Option (3)".

The correct order of words as they would appear in the English dictionary is:

4. Fondant
5. Fonder
6. Fondled
7. Fondue
8. Fontanel
9. Fontina

The correct order is '4, 6, 3, 2, 5, 1'

Hence the correct answer is "Option (2)".

The position and positional values or English Alphabets are:

The logic followed here is:

For, ‘ACTION’ is written as ‘DFWFLK’,

For, ‘BISHOP’ is written as ‘ELVELM’

Similarly, for ‘MATTER’

So, ‘MATTER’ will be written as 'PDWQBO'

Hence, the correct answer is "Option (4)".

The position of letters according to the English alphabet series:

The pattern followed here is:

So, "XVT" will replace the question mark (?) in the given series.

Hence, the correct answer is "Option (4)".

Given: 1^st January 2017 was Sunday

Now, the year 2016 was a leap year.

So, the number of days in 2016 = 366 days

And the total number of odd days = 366/7 = 52 weeks and 2 odd days.

Now, The days 2 days before Sunday = Sunday - 2 = Friday

So, The day on 1^st January 2016 = Friday

Hence, the correct answer is "Option (3)".

The positions of letter according to the English alphabet series:

The logic follows here is:

Option 1): GLP

Option 2): BEJ

Option 3): KNS

Option 4): QTY

The logic followed in Option (1) is different from others

Hence, the correct answer is "Option (1)".

Given:

Point A is 30 m to the east of Point B.

Point C is 43 m to the south of Point A.

Point C is 45 m to the east of Point D.

Point E is 14 m to the south of Point D.

Point F is 35 m to the east of Point E.

 

So, Point B is North-west of Point F.

Hence, the correct answer is "Option (2)".

BODMAS Table: 

Let's check each option one by one.

Given equation: [{(82 + 22) - (6 × 2)} ÷ (2 - 4)] × 2 = 24

Option 1) - and +

After interchanging the sign we get;

⇒ [{(82 - 22) + (6 × 2)} ÷ (2 + 4)] × 2 = 24

⇒ [{60 + 12} ÷ 6] × 2 = 24

⇒ [72 ÷ 6] × 2 = 24

⇒ 12 × 2 = 24

⇒ 24 = 24

⇒ LHS = RHS

Option 2) ÷ and +

After interchanging the numbers we get;

⇒ [{(82 ÷ 22) - (6 × 2)} + (2 - 4)] × 2 = 24

⇒ [{3.73 - 12} + (-2)] × 2 = 24

⇒ [{-8.27} + (-2)] × 2 = 24

⇒ [-10.27] × 2 = 24

⇒ -20.54 ≠ 24

⇒ LHS ≠ RHS

Option 3) ÷ and ×

After interchanging the numbers we get;

⇒ [{(82 + 22) - (6 ÷ 2)} × (2 - 4)] ÷ 2 = 24

⇒ [{104 - 3} × (-2)] ÷ 2 = 24

⇒ [101 × (-2)] ÷ 2 = 24

⇒ [-202] ÷ 2 = 24 

⇒ -101 ≠ 24 

⇒ LHS ≠ RHS

Option 4) + and ×

After interchanging the numbers we get;

⇒ [{(82 × 22) - (6 + 2)} ÷ (2 - 4)] + 2 = 24

⇒ [{1804 - 8} ÷ (-2)] + 2 = 24

⇒ [1796 ÷ (-2)] + 2 = 24

⇒ -898 + 2 = 24

⇒ -896 ≠ 24

⇒ LHS ≠ RHS

Hence, the correct answer is "Option (1)".

Given

Statements:

1. Some mammals are animals.
2. All animals are birds.

The least possible Venn diagram for the given statement is:

Conclusions:

1. All birds are animals - False (Because, some parts of birds are animals, so this can be a possibility only)
2. Some mammals are birds - True (Because, those parts of mammals which are animals, are also part of Birds.)

So, only conclusion II follows.

Hence, the correct answer is "Option (1)".

The logic followed here is:

So, '287' will replace the question mark (?) in the given series.

Hence, the correct answer is **"**Option (4)".
