Reasoning PYQs

Given: 20 * 60 * 40 * 20 * 10 * 0

According to the question, after replacing the signs:

Option 1) +, –, ×, ÷, = 

20 * 60 * 40 * 20 * 10 * 0 ⇒ 20 + 60 - 40 × 20 ÷ 10 = 0

⇒ 20 + 60 - 40 × 20 ÷ 10 = 0

⇒ 20 + 60 - 40 × 2 = 0

⇒ 20 + 60 - 80 = 0

⇒ 80 - 80 = 0

⇒ 0 = 0 (LHS = RHS)

Option  2) +, ×, –, ÷, =

20 * 60 * 40 * 20 * 10 * 0 ⇒ 20 + 60 × 40 - 20 ÷ 10 = 0

⇒ 20 + 60 × 40 - 20 ÷ 10 = 0

⇒ 20 + 60 × 40 - 2 = 0

⇒ 20 + 2400 - 2 = 0

⇒ 2420 - 2 = 0

⇒ 2418 ≠ 0 (LHS ≠ RHS)

Option  3) +, ×, –, =, ÷

20 * 60 * 40 * 20 * 10 * 0 ⇒ 20 + 60 × 40 - 20 = 10 ÷ 0

⇒ (20 + 60 × 40 - 20) × 0 = 10

⇒ (20 + 2400 - 20) × 0 = 10

⇒ (2420 - 20) × 0 = 10

⇒ 2400 × 0 = 10

⇒ 0 ≠ 10 (LHS ≠ RHS)

Option  4) ÷, –, ×, +, =

20 * 60 * 40 * 20 * 10 * 0 ⇒ 20 ÷ 60 - 40 × 20 + 10 = 0

⇒ 20 ÷ 60 - 40 × 20 + 10 = 0

⇒ 0.33 - 40 × 20 + 10 = 0

⇒ 0.33 + 10 - 80 = 0

⇒ 10.33 - 80 = 0

⇒ -69.67 ≠ 0 (LHS ≠ RHS)

Hence, "Option 1" is the correct answer.

The correct mirror image of the given figure is:

Hence, the correct answer is "Option 4".

Given: 144 ÷ 12 + 12 −12 × 12 = 1

According to the question, after interchanging the signs:

Option 1) = and ×

144 ÷ 12 + 12 −12 × 12 = 1 ⇒ 144 ÷ 12 + 12 −12 = 12 × 1

⇒ 144 ÷ 12 + 12 −12 = 12 × 1

⇒ 12 + 12 −12 = 12

⇒ 24 −12 = 12

⇒ 12 = 12 (LHS = RHS)

Option  2) + and −

144 ÷ 12 + 12 −12 × 12 = 1 ⇒ 144 ÷ 12 - 12 + 12 × 12 = 1

⇒ 144 ÷ 12 - 12 + 12 × 12 = 1

⇒ 12 - 12 + 12 × 12 = 1

⇒ 12 + 144 - 12 = 1

⇒ 156 - 12 = 1

⇒ 144 ≠ 1 (LHS ≠ RHS)

Option  3) ÷ and −

144 ÷ 12 + 12 −12 × 12 = 1 ⇒ 144 - 12 + 12 ÷ 12 × 12 = 1

⇒ 144 - 12 + 12 ÷ 12 × 12 = 1

⇒ 144 - 12 + 1 × 12 = 1

⇒ 144 + 12 - 12 = 1

⇒ 156 - 12 = 1

⇒ 144 ≠ 1 (LHS ≠ RHS)

Option  4) × and −

144 ÷ 12 + 12 −12 × 12 = 1 ⇒ 144 ÷ 12 + 12 × 12 - 12 = 1

⇒ 144 ÷ 12 + 12 × 12 - 12 = 1

⇒ 12 + 12 × 12 - 12 = 1

⇒ 12 + 144 - 12 = 1

⇒ 156 - 12 = 1

⇒ 144 ≠ 1 (LHS ≠ RHS)

Hence, "Option 1" is the correct answer.

The figure which when put in place of '?' will logically complete the pattern is shown below:

Thus, option Figure 2 will logically complete the pattern given.

Hence, "Option 2" is the correct answer.

The logic followed here is:

Hence, "Option 2" is the correct answer.

The logic followed here is:

1. The number of '

' is increasing and then decreasing subsequently.

Thus, the final series is:

Hence, "Option 4" is the correct answer.

The logic followed here is:

1) A new element is added in each box subsequently.

2. All the elements shift clockwise subsequently.

Thus, the final series is:

Hence, "Option 4" is the correct answer.

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

Conclusions:

I. All plants are trees → Does not follow (As all shrubs are trees and some plants are shrubs. As whole shrubs comes in trees and has some part common with plants, so it is possible but not definite.)

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

III. No plant is a tree → Does not follow (As all shrubs are trees and some plants are shrubs. As whole shrubs comes in trees and has some part common with plants, therefore it is false.)

∴ Here, Only conclusion II follows.​

Hence, the correct answer is "Option 3".

The logic followed here is:

1. First box series →

The center element is replaced by new element.

The rest of the elements shift clockwise subsequently.

2. Second box series → 

The 2^nd column elements shift anticlockwise in the downward direction subsequently.

The 1^st column elements shift to the 3^rd column diagonally.

The 3^rd column elements shift to the 1^st column at the same position.

Thus, the final series is:

Hence, "Option 4" is the correct answer.

The logic followed here is:

‘CODY’ is written as ‘CQDA’

And,

‘DINO’ is written as ‘DKNQ’

Similarly,

‘RAIN’ is written as

​

Hence, "Option 2" is the correct answer.

The image embedded in the given figure is as shown below :

∴ Here, the given figure is embedded in the option figure 1.

Hence, the correct answer is "Option 1".

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

1) Number of triangles = Number of parts × Number of diagonals

= 4 × 2 ⇒ 8

2) Number of triangles = Number of parts × Number of diagonals

= 4 × 2 ⇒ 8

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

= [2 × (1 + 2)] ÷ 2

= [2 × 3] ÷ 2

= 6 ÷ 2

= 3

As there are 2 same types of triangles, therefore total number of triangles will be (3 × 2) = 6 

4. Number of triangles = 4

Thus, there are a total of (8 + 8 + 6 + 4) = 26 triangles.

Hence, "Option 1" is the correct answer.

The figure that will look like the paper when unfolded is shown below:

Thus, option Figure 1 will look like the paper when unfolded.

Hence, "Option 1" is the correct answer.

The correct mirror image of the given figure is:

Hence, the correct answer is "Option 2".

The image embedded in the given figure is as shown below :

∴ Here, the option figure 1 is embedded in the given figure.

Hence, the correct answer is "Option 1".

The logic followed here is:

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

Now,

For (101, 106, 111):

⇒ (101 + 111) ÷ 2 = 212 ÷ 2 = 106.

For (214, 198, 182)

⇒ (214 + 182) ÷ 2 = 396 ÷ 2 = 198.

Similarly, for (163, 156, 149):

⇒ (163 + 149) ÷ 2 = 312 ÷ 2 = 156.

Hence, the correct answer is Option 4.

The logic followed here is:

​

Hence, "Option 4" is the correct answer.

The correct mirror image of the given figure is:

Hence, the correct answer is "Option 3".

The figure which when put in place of '?' will logically complete the pattern is shown below:

Thus, option Figure 1 will logically complete the pattern given.

Hence, "Option 1" is the correct answer.

The logic followed here is:

EDGE : CEBC

And,

ICON : LMAG

Similarly,

KICK : ?

​

Hence, "Option 2" is the correct answer.
