Reasoning PYQs

Let the age of father be 'x' and Reena's be 'y'

The sum of their age is 60.

 x + y = 60 --------- (1)

The difference between their age is 36.

 x - y = 36 -----------(2)

From, eq. 2 . x = 36 + y ------- (3)

Substituting eq. 3 in eq. 1

 36 + y + y = 60

 2y = 60 - 36

 2y = 24

 y = 12

Substituting the value of y in eq. 1 

 x + y = 60

 x + 12 = 60

 x = 60 - 12

 x = 48 ; y = 12

 Therefore, Reena's father's age is 48.

Hence, the correct answer is '48'.

Four friends are sitting in a row facing north.

1. B is at one end

    

 2. D is between B and C

    

 3.  A is second to the right of D (fig. b gets canceled)

    

According to the arrangements,

Statement 1: A is sitting at one end ⇒ True

Statement 2: B is sitting to the immediate left of D ⇒ True

Statement 3: C is sitting to the immediate right of D ⇒ True

Statement 4: A and B are sitting next to each other ⇒ False

Hence, the correct answer is option 4.

Preparing the family tree using the following symbols

The family tree diagram is shown below:

 

According, to the tree diagram there are 4 male members in the family. The gender of E is not defined.

Hence, the correct answer is '4'.

Family tree chart:

1. Sukrit is the son of Garv.

 

2. Suyog's only sister is married to Garv.

 

 

3) Suyog is the son of Anshum.

4. Anshum is the wife of pratap.

 

 

5) Eena's husband is the only son of Pratap.

 

 

6) Bani is Sukrit's mother.

7) Eena is Jatin's mother.

 

 

 

Clearly, we can see that Pratap is paternal grandfather of Jatin.

Hence, the correct answer is "Paternal grandfather".

The code for each word is shown below:

The code for 'my' is 6 and for 'shoes' is 4.

Therefore, the code for 'my shoes' either will be 64 or 46.

According, to the given option 46 is the correct answer.

The position of the letters according to the English alphabet series:

The logic followed in the given series is,

Hence, the correct answer is 'TOIL'.

The logic here followed is,

In a row ⇒ (1^st number × 2^nd number) × 2 = 3^rd number

• Considering the 1^st row, i.e  14, 12, and 336.

           (14 × 12) × 2 = 336

           168 × 2 = 336

           336 = 336 ​

• In the same way, the 2^nd row i.e 15, 18, and 540.

          (15 × 18) × 2 = 540

           270 × 2 = 540

           540 = 540

• Similarly, in the third row, i.e 16, a, and 416

           (16 × a) × 2 = 416

           16a = \(\frac{416}{2}\)

           16a = 208

           a = \(\frac{208}{16}\)

           a = 13

Hence, the correct answer is '13'.

Given:

B + C = 150

(B-12) +(C+12) = 150

B-12 = 0.5(C+12)

B = number of students in biology

C = number of students in chemistry

Solution:

B - 12 = 0.5C + 6

B = 0.5C + 18

Now, let's put the value of B in the first equation formed.

0.5C + 18 + C = 150

1.5C = 132

C = 132/1.5 = 88

Since, 12 students shifted from biology to chemistry,

the numbers of students in chemistry now = 88 = 12 = 100

The position of the letters according to the English alphabet series:

Let's check the given letter clusters:

1. BDHNV

 

2. DFJPX

 

3. HJNTB

 

4. KMQWF

 

The difference between W and F doesn't follow the pattern with respect to other letter-clusters.

Hence, the correct answer is 'KMQWF'

The image found when the mirror is placed on the right side is shown below:

Hence, the correct answer is 'option 4'

The position of the letters according to the English alphabet series:

The logic followed here is,

Hence, the correct answer is 'OFYW'.

The pattern here follows is,

Here, in the series itself, there are two series followed

 

Hence, the correct answer is '20'.

The number given in the circle defines the shaded area to move in the given number of positions.

• In fig. a the number given is '3', which says the shaded part to move 3 parts further in the partition shown.
• In fig. b the number given is '3', which says the shaded part to move 3 parts further.
• In fig. c the number given is '2' which says the shaded part to move 2 parts further.
• in fig. d the number given is '3' which says the shaded part to move 3 parts further.
• Similarly, in fig. e the number given is '1', which says the shaded part to move 1 part further.
• Therefore, the next pattern formed is:

 

Hence the correct answer is 'option 4'.

The positional value table is as follows:

The pattern followed here is:

• In NEUTSE ∶ EFPVXZ​ 
• Arrange NEUTSE in Alphabetical order → E E N S T U
• In ZWURST ∶ ? ​
• Arrange ZWURST in Alphabetical order → R S T U W Z

​Hence, "RTVXAE" is the correct answer.

The pattern followed here is:

( 1^st Number × 2^nd Number ) × 2 = 3^rd Number

• ​(15, 5, 150)

          ⇒ (15 × 5) × 2 = 150

          ⇒  75 × 2 = 150

          ⇒ 150 = 150

• (16, 4, 128)

          ⇒ (16 × 4) × 2 = 128

          ⇒ 64 × 2 = 128

          ⇒ 128 = 128

• (7, 7, 98)

          ⇒ (7 × 7) × 2 = 98

          ⇒ 49 × 2 = 98

          ⇒ 98 = 98

• (11, 4, ?)

          ⇒ (11 × 4) × 2 = ?

          ⇒ 44 × 2 = ?

          ⇒ 88

The number that can replace the question mark is '88'

Hence, the correct answer is '88'

The Venn diagram that follows the relation of Peaches, Lychees, and Fruits is shown below:

Reason: Both peach, as well as lychee, are fruits, but peach is a seedless fruit. 

Statement 1: Do not follow the above pattern.

Statement 2: Do not follow the above pattern.

Statement 3: Follows the above pattern.

Statement 4: Do not follow the above pattern.

Hence, the correct answer is 'option 3'.

The given figure is embedded in the figure which is shown below:

 

Hence, the correct answer is 'option 3'.

Given information,

• In the morning Riti walks towards the east and sees her friend Sanju coming from a direction

 

• Sanju's shadow towards his right. (Sanju's right).
• Given above, morning time of the day and we know sun rises from the East.
• According, to which Sanju will be coming from North direction, then and only then the shadow will be towards his right.
• Sanju is facing south but coming from the north direction.

 

Hence, the correct answer is 'North'.

From the information given:

Step 1: Out of 200 people, 30% of the guests have dressed as animals.

Dressed as animal = 30% of 200 = 60 people

People left = 200 - 60 = 140

Step 2: 40% of the remaining guests have dressed as birds.

Dressed as birds = 40% of 140 = 56

People left = 140 - 56 = 84

Step 3: 50% of the remaining guests have dressed as clowns.

Dressed as clowns = 50% of 84 = 42

Step 4: The remaining guests have dressed as plants.

Peoples left = 42

Hence the correct answer is option 3)

Venn Diagram:

 

Conclusion:

I. All colours being dark is a possibility ⇒ Follow ⇒ (All colours can be dark because it is a possibility)

II. Some reds are dark ⇒ Follow ⇒ (Some green are reds and all green are part of dark, so some reds are dark)

III. Some reds are colours ⇒ Follow ⇒ (All colours are red, so definitely some reds are colours)

Hence, the correct answer is 'All conclusions follow'.
