  1. 1,5,3,2,4
  2. 2,1,3,5,4
  3. 3,5,1,2,4
  4. 5,4,2,1,3

Answer: C-3,5,1,2,4

Education - Work - Money - Social standing - Wellbeing

Q.2 ) Arrange the words in the following list in a meaningful order. 1. Country 2. Furniture 3. Forest 4. Wood 5. Trees

Option A - 1,2,3,4,5

Option B - 5,4,3,2,1

Option C - 3,5,4,2,1

Option D - 1,3,5,4,2

Answer: D-1,3,5,4,2

Solution - Country->Forest->Trees->wood->Furniture

Logical sequence of getting by-product from wood starting from County & the Forest.

Q.3 ) What could be the next term in the series QAR, RAS, SAT, TAU, _____

  1. UAV
  2. UAT
  3. TAS
  4. TAT

Answer: UAV

Solution: If we look at the series, the third letter of the first word is the first letter of the next consecutive word. Along with this, the middle term is not changing, so finally, to find the third letter, we can observe that the first and third letters of the word are two consecutive letters. 

So the first letter is the third letter of TAU, which is U. And the second letter is the repeating letter A, And the third letter is consecutive of U, which is V.

Q.4 ) Which of the following options could be the next term?

9, 18, 11, 16, 14, 13, 18, 9, 23, ? 

  1. 18 
  2. 4
  3. 15
  4. 2

Answer: B-4

Solution: Let's take a look at all of the even place terms and all of the odd place terms individually.

The Oddly placed terms are:

9, 11, 14, 18, 23 – if we calculate the difference between two consecutive numbers then it would look like.

The Even placed terms are:

18, 16, 13, 9, ? – And, similarly, if we calculate the difference here, it will go in a similar magnitude but with a negative sign.

So, In order to calculate the last term, we need to subtract five from nine.

Which is:  9-5 = 4.

Problem Solving

Q.5 ) Esha, Priya, Sejal, and Ava went to a college party with Finn, Leo, Axel, and Jack. There was going to be a dance party for everyone. Esha refused to dance with Finn or Axel, Sejal only knew disco dance, and Leo and Axel had never heard of disco. Ava and Axel are furious rivals who refuse to dance together. If given the option, Axel will not dance with Ava. Sejal is Jack's partner. Ava had a dancing partner, but who was it?

  1. Finn
  2. Leo
  3. Axel
  4. Jack

Answer: A-Finn

Explanation: Let’s first write down the important pieces of information given in the problem.

  • Esha refuses to dance with either Finn or Axel.
  • Sejal refuses to dance with Leo and Axel because she only knows disco, and neither Leo nor Axel do.
  • Because Ava and Axel are bitter foes, Ava will not dance with him.
  • Leo isn't interested in dancing with Ava.
  • Jack and Sejal are dancing together.

Jack and Sejal are dancing together. So, Esha, Priya, and Ava are the remaining girls, and Finn, Leo, and Axel are the remaining boys. At the same time, Esha isn't interested in dancing with Finn or Axel.

So, as a result, Esha will perform with Leo. And then Priya and Ava are the two girls on the left.

Finn and Axel are the only boys left. Ava isn't going to dance with Axel. So, Finn and Ava will dance.

Therefore, Axel and Priya will dance together.

Sejal <------------> Jack

Esha <------------> Leo

Ava <------------> Finn

Priya <------------> Axel

Q.6 ) How am I related to my grandmother's only child's husband's mother?

  1. Grandmother
  2. Mother
  3. Sister
  4. Aunt

Answer: Grandmother

Explanation: If we think clearly about the relationship mentioned above, then we can easily summarise that My mother is the only child of my grandmother. And though My father is my mother's husband. My grandmother is my father's mother.

Q.7 ) She is my mother's mother's son's daughter, Harry said while holding up a photograph. What is the relationship between the person in the photograph and Harry?

  1. Sister
  2. Niece
  3. Mother
  4. Cousin

Answer: Cousin

Explanation: Harry’s mother’s mother’s son is the uncle of harry. Harry’s uncle’s daughter is Harry's cousin.

Q.8 ) John loses his way in a very dense jungle. He travels away from his tent at random but mathematical in a very interesting sense. He walks one mile east first, then half a mile north. Then 1/4 mile to the west, 1/8 mile to the south, and so on to complete the loop. Finally, how far away from his camp is he, and in which direction is he heading?

  1. 0.98 miles
  2. 0.56 miles
  3. 0.76 miles
  4. 0.44 miles

Answer: 0.76 miles

Explanation: We can see that he is moving into a loop which will look like

To reach the camp, John must go 0.75 miles west and 0.375 miles south.

Didn't get how? Let's see this in detail then.

How: First, the soldier moves 1 mile east of the camp, then 1/2 mile north of camp. Then it moves 1/4 mile to the west or 0.25 mile. Then it's 1/8 mile to the south (0.125 miles).

Now all we have to do is subtract the value of camp to the east from the value of camp to the west = 1 mile – 0.25miles(1/4) = 0.75 miles

Similarly, 0.50 miles(1/2) – 0.125 miles(1/8) = 0.375 miles for north and south

As a result, the soldier must go 0.75 miles west and 0.375 miles south in order to return to camp.

And to calculate that, we will use the basic Pythagoras theorem.

square root of ((0.75)^2 + (0.125)^2)

= square root of ((3/4)^2+(1/8)^2)

= square root of ((9/16) +(1/64))

= square root of (36+1)/64

= square root of (37/64)

= 0.76

And, the final direction will be in South - West.

Q.9 ) A young lady departs from her home. She walks 30 meters in a north-westerly direction, then 30 meters in a south-westerly direction. She then travels 30 meters to the southeast. She finally makes her way back to her residence. In which direction does she seem to be heading?

  1. Northeast
  2. Southeast
  3. Southwest 
  4. Northwest
  5. None of these

Answer: Northeast

Explanation: Let’s try to understand this problem with a diagram.

By just looking at the figure, we can easily say that, In order to return back to the house, she would go in the north-east direction.

Figure and Fractal Analysis

Q.10 ) Select a box that resembles the one made from the given sheet of paper (X).
 

 

 

  1. Only 1
  2. Only 2
  3. Only 1 and 3
  4. 1,2,3 and 4

Answer: Only 2

Explanation: Here, we can observe that 

A lies opposite D

B lies opposite F

C lies opposite E

The diagram (X) provided is similar to the one shown above. When the sheet in Diagram (X) is folded to form a cube, 'F' is placed opposite 'B,' 'E' is placed opposite 'C,' and 'A' is placed opposite 'D.'. As a result, the cube in Diagram (1) with 'F' next to 'B,' the cube in Diagram (3) with 'E' next to 'C,' and the cube in Diagram (4) with 'A' next to 'D' cannot be created.

As a result, only the cube shown in Diagram(2) can be created.

Q.11 ) Select the appropriate option for how the pattern will appear when the transparent sheet is folded along the dotted line.


 

 

  1. 1
  2. 2
  3. 3
  4. 4

Answer: Diagram 4

Explanation: The curved lines in Diagram(1) are in the wrong order. The vertical and horizontal lines in Diagrams (2) and (3) are incorrectly combined.

As a result, Diagram (4) is the proper response.

Decision Making 

Q.12 )   Given Statements:

All liquids are solids.

All gases are clouds.

Some solids are gases.

Conclusion to be followed:

  1. Some clouds are solids
  2. Some solids are clouds
  3. Some clouds are liquids
  4. Some gases are liquids

 

  1. Only II follows
  2. Only I and IV follow
  3. Only IV follows 
  4. Only III follows

Answer: Only I and IV follow.

Explanation: Let’s try to understand this question by Venn diagrams for each state.


 

Q.13 ) In which year was David born?

Statement 1: David is 25 years younger than his mother at the present moment.

Statement II: David's younger brother, who was born in 1964, is 33 years younger than his mother.

  1. Statement-I alone is sufficient, while Statement-II alone is not sufficient.
  2. Statement-II alone is sufficient, while Statement-I alone is not sufficient.
  3. Either Statement-I or Statement-II is sufficient.
  4. Neither Statement-I nor Statement-II is sufficient.
  5. Both Statement-I and Statement-II are sufficient.

Answer: Both Statement-I and Statement-II are sufficient

Explanation: According to both Statement-I and Statement-II, we get to know that David is (33 - 25) = 8 years older than his brother, who was born in 1964. So, David was born in 1956.

Prepositional Reasoning

Q.14 ) There are three categories of people on this island. Nobles, who always tell the truth, scoundrels, who always lie, and spies, who can do either. You'll encounter three persons in these puzzles: a noble, a scoundrel, and a spy. The task is to figure out who is who. "I am a Noble," says A. "A is a Noble," says B. "If you asked me, I'd say A is the spy," C says.

  1. It can’t be determined. 
  2. Scoundrel
  3. Noble
  4. Spy

Answer: Can’t be determined.

Explanation:

If A is telling the truth which will lead to proving that B is saying the truth, then we have to conclude that C is lying. Thus the answer would look like  

A → Noble

B → spy

C → scoundrel

However, if we also include the case where we will consider that A and B are lying, while C is telling the truth, then the answer would be 

A → spy

B → scoundrel

C → Noble

As a result, Both answers could be correct. Therefore the answer is unpredictable and impossible to anticipate.

Q.15 ) In the year 2003, February had 28 days and the year had 365 days. In 2004, there were 29 days in the month of February, and there were 366 days in the whole year. Which of the following would be the day for March 11, 2004, if the date March 11, 2003, is a Tuesday?

  1. Monday
  2. Tuesday
  3. Wednesday
  4. Thursday

Answer: Thursday

Explanation: Every year, the number of days is raised by one odd day. And, in a leap year, it is increased by two odd days.

So, the 11th of March 2003 is a Tuesday, and the 11th of March 2004 is a Thursday.

Q.16 ) What is the number of identical pieces obtained if two, three, and four cuts are made parallel to separate faces of a cube?

  1. 40
  2. 27
  3. 60
  4. 25

Answer: 60

Explanation: 

You'll get "x+1" pieces for "x" cuts.

As a result, the no. of pieces you will get is = (2+1)*(3+1)*(4+1)

=3*4*5

=60 pieces.

Visual / Spatial Reasoning

Q.17 ) Which of the following responses can be made by folding the figure given in the question from the possibilities offered?

 


  1.  

Answer: B

Explanation: The rotated figure will be our answer if we rotate the section drawn with blue in a clockwise orientation.
 

Q.18 ) How many people in the given figure enjoy both cricket and tennis?

 

  1. 17
  2. 32
  3. 27
  4. 15

Answer: 32

Explanation:

Cricket fans = 9,12,15,17

Tennis fans = 8,15, 17, and 21.

Those who enjoy both= 15 + 17 = 32
