CRPF Head Constable Mock Test - 1 - CRPF Head Constable MCQ

The pattern follows here is:
From the first diagram:
= (12²+14²) − (11²+8²)
= (144+196) − (121+64)
= 340 − 185
= 155
From the second diagram:
= (13²+17²) − (9²+12²)
= (169+289) − (81+144)
= 458 − 225
= 233
From the third diagram:
= (16²+20²) − (12²+15²)
= (256+400) − (144+225)
= 656 − 369
= 287
Thus, "287" is the correct answer.

2, 1, 4, 5, 3 is the correct logical and meaningful order.
Meaningful order of words is:
Crime → Police → Judge → Judgement → Punishment
First crime will occur then police will come then police pass the case to the judge then judgement will pass and finally punishment given to a person convicted of a crime.

The Logic followed here is:
The Arrow is moving in his same position Clockwise and the circle is changing its position when the new shape is inserted.
The Square which has 4 sides its side increases by +1 and changes to Pentagon of side 5 same as the Triangle which has 3 sides its side increases by +1 and changes to Square of 4 sides.

The least possible diagram for the given statements is as follows,

Conclusions:
I. No white is Blue. → False (It is possible but not definite)
II. Some white is blue. → False (It is possible but not definite)
Conclusions I and II are complementary pair.
So, either conclusion I or II follows.

The pattern followed here is:
V – 4 = R
R – 5 = M
M – 6 = G
G – 7 = Z

According to the given information, we can draw the following diagram:

So, Rohit is now standing in front of West direction.

From the given information,

1. H is daughter-in-law of D who has only one child. (So, D has only one son)
2. F and G are grandson of D. (F and G are sons of H)
3. A is father of B who is brother-in-law of C who is son of D. (As D has only one child so B’s sister is wife of C)
4. E is mother-in-law of C. (So, E is wife of A)
5. E has only two children, one son and one daughter. (So, B is son of E and H is daughter of E)

D’s gender is not mentioned.
So, D’s relation with G cannot be determined.

Given,

We get,

Therefore, the answer is LOMS.

Facing: North
1) Q is sitting second from on the extreme ends. 
(Here two cases are possible Case I Q is sitting second from the extreme North end Case II where Q is sitting second from the extreme south end) 
2) Only two people are sitting between Q and


3) S is sitting seventh to the right of M. 
Here Case II eliminates as Q is sitting second from the extreme end so S will not sit beyond.
4) L is sitting exactly in between Q and S. 

5) Only one person is sitting between S and O. 
(As O can sit both the sides of S. So, In Case I.I O is sitting second to the right of S and in Case I.II O is sitting second to the left of S.)
6) O is sitting third to the left of R. 


7) R is not an immediate neighbour of S.
Here Case I.II eliminates as R is not an immediate neighbour of S.
8) P is sitting second to the left of N, who is sitting fourth to the right of R. 
The final arrangement

So, 21 people are sitting in the row.
We always count the number of person whether they are defined or not in the final arrangement so here we will count all the seats as these are for the persons.

Facing: North
1) Q is sitting second from on the extreme ends. 
(Here two cases are possible Case I Q is sitting second from the extreme North end Case II where Q is sitting second from the extreme south end) 
2) Only two people are sitting between Q and


3) S is sitting seventh to the right of M. 
Here Case II eliminates as Q is sitting second from the extreme end so S will not sit beyond.
4) L is sitting exactly in between Q and S. 

5) Only one person is sitting between S and O. 
(As O can sit both the sides of S. So, In Case I.I O is sitting second to the right of S and in Case I.II O is sitting second to the left of S.)
6) O is sitting third to the left of R. 


7) R is not an immediate neighbour of S.
Here Case I.II eliminates as R is not an immediate neighbour of S.
8) P is sitting second to the left of N, who is sitting fourth to the right of R. 
The final arrangement
So, N is sitting at the extreme right end of the row.

It follows (+5, +5) pattern.

Given: CANDLE is written as FMEOBD
The logic followed here is:

Similarly,

Therefore, HOJYJG is the correct answer.

IISC Bengaluru, IIT Hyderabad, and NIT Calicut are the technical colleges in India. While Kotak Mahindra Bank is a Bank in India.

Here, the alphabets and their positions are shown as below:

The logic here is: The first letter is added by 3 to get the next 1st letter. Similarly the 2nd letter by +7, 3rd letter by +11 and the 4th letter by +15.
Thus, we have:

Hence, the correct answer  is 'CORV'
Confusion Point: Keep in mind the positions of all the letters. 

The pattern for the code is as follows:-

Similarly,

Hence, BOMBAY will be written as AMJXVS.

The pattern followed here is:
Logic: (First number + Second number) × 11 = Third number.
(27, 5, 352)
⇒ (27 + 5) × 11 = 32 × 11 = 352 Third number.
And,
(51, 2, 583)
⇒ (51 + 2) × 11 = 53 × 11 = 583 Third number.
Similarly,
(9, 41, 550)
⇒ (9 + 41) × 11 = 50 × 11 = 550 Third number.
Hence, the correct answer is "(9, 41, 550)".

Friends: A, B, C, D, E, F and G, facing north.
1) ​A is sitting to the extreme right and B to the extreme left.

2) D is the neighbor of A and G therefore D should be 2nd from right and G 3rd from right.

3) C is the neighbor of E and B therefore C should be sitting 2nd from left and E 3rd from left.

• The only position now left for F is in the middle.

Thus F sits in the middle position.
Hence, the correct answer is "F".

According to the English alphabet series and its positional value:

The logic in this is that the word has been coded by adding 3 and 2 in the alternate letters of the word.
Let's check this logic in the word RABBIT,

Similarly, verifying the logic in the word DONKEY,
 
Now, using the same logic TURTLE can be coded as,
 
Hence, the correct answer is "WWUVOG".

Given: M B V _ M B _ CM _ V C _ B V C M B _ _
Let's check each option:
1)  CMCBMC → M B V C M B M CM C V C B B V C M B M C
2)  CVBMVC → M B V C M B V CM B V C M B V C M B V C
3)  MVCVB → M B V M M B V CM C V C V B V C M B B _
4)  BCVBCM → M B V B M B C CM V V C B B V C M B C M
So, by putting option 2) in the series "M B V C" is repeating itself.
Hence, ‘CVBMVC’ is the correct answer.

As you can see, the figure in option 1 is the right one to complete the pattern.
Hence option 1 is the right answer.

Given series: (Left) Q A Y S R E Z I L X B O P A R D I H O U K (Right)
Required pattern: Vowel → Consonant → Vowel
So, There are 3 consonants are there, each of which is immediately preceded by a vowel and also immediately followed by a vowel.
Hence, "Option 3" is the correct answer.

According to given conditions,

Given : E $ G $ Y @ K + W
So,

• E $ G → E is the mother of G.
  
• G $ Y → G is the mother of Y.
  
• Y @ K → Y is the brother of K.
  
• K + W → K is the husband of W.
  

Thus, according the final family tree E is the maternal grandmother of K.
Hence, "Maternal grandmother" is the correct answer.

After unfolding the given paper the figure formed is as shown below :

Hence, the correct answer is "Option 4".

The logic followed here is:
Second number = (First number × 3) + 2
⇒ 33 ∶ 101 → (33 × 3) + 2 = 99 + 2 = 101
⇒ 35 ∶ 107 → (35 × 3) + 2 = 105 + 2 = 107
Similarly,
⇒ 39 ∶ ? → (39 × 3) + 2 = 117 + 2 = 119
Hence, option (2) is the correct answer.

*-From the given information:/
Step 1: Salman is an immediate neighbour of both Kiran and Shwetha. Bala is sitting second right to Salman.

We place Salman in between Shwetha and Kiran and then place Bala second to the right of Salman.
Step 2: Shwetha is sitting third to the left of Bala. Akshay is an immediate neighbour of both Bala and Nishitha.

We place Akshay next to Bala and then place Nishitha at the last spot left.
From the arrangement, we can see that Shwetha is the immediate neighbour of Nishitha and Salman.
Hence the correct answer is option (3).

Given:
Length of first train L1 = 400 m
Length of second train L2  = 350 m
Speed of first train S1= 80 km/hr 
Speed of second train S2 = 90 km/hr
Calculations:
The relative speed of two trains in the same direction = S1 – S2
(90 – 80) = 10 km/hr = 10 × (5/18)m/s
Let, Total distance = sum of the length of two trains = 750 m
Now, the time is taken to cross each other = 

∴ 270 sec of time will be required to cross each other.

The logic followed here is:

Therefore, ‘56’ is the correct answer.

The ascending order is: 0.306,3.06,3.306,3.6

Given,
The speed of the current is 1.25x km/hr.
And the speed of a boat in still water is 12 km/hr more than that of current.
According to the question,
The speed of a boat + The speed of the current = 
1.25x + 1.25x + 12 = 160/5
Or, 2.5x = 20
Or, x = 8

∴ Required Ratio = 42 ∶ 221
