Reasoning PYQs

The least possible Venn diagram is :

Conclusions:

I. Some doors are pillows. → True (as some pillows are doors)

II. All beds are doors. → False (It is possible but not definite)

Hence, "only conclusion I follows" is the correct answer.

A possible family tree diagram is :

Hence, Levi is the brother in law of Christa.

Here, the digits of the first number in the series are multiplied to get the second number, then the digits of the second number are multiplied to get the third number and so on.

Therefore, the pattern followed here is :

9 × 4 = 36

3 × 6 = 18

1 × 8 = 8

Hence, 8 is the correct answer.

Given expression : 9 X 3 X 6 X 2 X 9

1. Replacing Xs with ÷, ×, =, × in the same order, we get

9 ÷ 3 × 6 = 2 × 9

Applying BODMAS rule on L.H.S and R.H.S, we get

L.H.S = 9 ÷ 3 × 6

= 3 × 6

= 18

R.H.S = 2 × 9

= 18

L.H.S = R.H.S 

2) Replacing Xs with ÷, ×, =, - in the same order, we get

9 ÷ 3 × 6 = 2 - 9

Applying BODMAS rule on L.H.S and R.H.S, we get

L.H.S = 9 ÷ 3 × 6

= 3 × 6

= 18

R.H.S = 2 - 9

= -7

L.H.S ≠ R.H.S 

3) Replacing Xs with ×, =, -, ÷  in the same order, we get

9 × 3 = 6 - 2 ÷ 9

Applying BODMAS rule on L.H.S and R.H.S, we get

L.H.S = 9 × 3

= 27

R.H.S = 6 - 2 ÷ 9

= 6 - 0.22

= 5.78

L.H.S ≠ R.H.S 

4) Replacing Xs with ×, ÷, +, =  in the same order, we get

9 × 3 ÷ 6 + 2 = 9

Applying BODMAS rule on L.H.S and R.H.S, we get

L.H.S = 9 × 3 ÷ 6 + 2

= 9 × 0.5 + 2

= 4.5 + 2

= 6.5

R.H.S = 9

L.H.S ≠ R.H.S 

Hence, "÷, ×, =, ×"  is the correct answer.

Let the price of the product be Rs 100

When the price is decreased by 35%, it becomes 100 - 35% of 100 = 100 - 35 = 65

Then it is increased by 20%. It becomes 65 + 20% of 65 = 65 + 13 = 78

Net change in the price of the product = {(Original Price - Changed Price)/Original Price} × 100

= {(100 - 78)/100} × 100

= 22

Hence, 22% is the correct answer.

Concept:

1. We have to check the conclusions are 100% match with the statement. If the conclusion is 100% match with the given statement then the conclusion is true. If there is a 1% chance of not following the statement then the conclusion is considered to be false.

2. The possibility case can be considered to be "false" in "definite case".

3. In Possibility case, either "can" or "possible" word must be present.

Explanation

The least possible Venn diagram is :

Conclusion:

I. All fans are fishes. → False (It is possible but not definite)

II. All swords are fans. → False (It is possible but not definite)

Hence, neither conclusion I nor II follows.

 

Additional Information

The pattern followed here is :

Row 1 : (8 + 5) × 3 = 13 × 3 = 39

Row 2 : (3 + 5) × 3 = 8 × 3 = 24

Row 3 : (4 + 5) × 3 = 9 × 3 = 27

Hence, 27 is the correct answer.

Honey is a viscous food substance made by honey bees and some related insects.

Milk is a liquid produced by all matures female mammals after they have given birth.

Dog is an animal.

So, there is no relationship between Honey, Milk, Dog.

The logical Venn diagram is :

Hence, option 2 is the correct answer.

The path followed by Khanna is :

Khanna is 60 m in the east direction from the starting point Z.

Hence, 60 m, East is the correct answer.

The least possible Venn diagram is :

Conclusions:

I. Some mugs are pens. → True

II. All pens are mugs. → False (It is possible but not definite)

Hence, only conclusion I follows.

The pattern followed here is :

Hence, 60 is the correct answer.

The pattern followed here is :

1762 ÷ 2 = 881

Similarly, 

2578 ÷ 2 = 1289

Hence, 1289 is the correct answer.

The pattern followed here is :

Hence, G is the correct answer.

The pattern followed here is :

Hence, F is the correct answer.

The diagrammatic representation of the coded statements is as follows :

Therefore, the word and code combination is :

 Hence, "They Will" is the correct answer.

A is sweeter than D but not as sweet as B.

• B > A > D

D is sweeter than C.

• B > A > D > C

E and B are not as sweet as F. E is sweeter than A. 

• Case 1 : F > E > B > A > D > C
• Case 2 : F > B > E > A > D > C

In both the cases, C is the least sweet fruit.

Hence, C is the correct answer.

When opened, the paper will appear as :

Hence, option 2 is the correct answer.

Ant and Bee both come under the category of Insects. 

The logical Venn diagram is :

Hence, option 3 is the correct answer.

The question figure is hidden in the figure given in option 3 as :

Hence, option 3 is the correct answer.

The shaded part on the right side in the first box is moving in an anti-clockwise direction. It moves 1 step then 2 steps then 3 steps and so on.

The other shaded part on the left side in the first box is moving in a clockwise direction. It moves 1 step then 2 steps then 3 steps and so on.

Thus, in the fourth and the fifth figures, the shaded parts overlap each other.

When they overlap each other it looks like one shaded portion is disappeared as the position of both the shaded portion is the same. 

Hence, option 2 is the correct answer.
