CISF Head Constable Mock Test - 1 - CDS MCQ

In all the figures except (B), all the figures except are the rotated form of the same figure.

Adjacent colors to pink are grey, green, brown, purple.
Adjacent elements can never be on the opposite surface of a particular element.
The only element left is golden.
So, Golden will be opposite to the face having pink.

According to the given information-
428 → (4)² + (2)² + (8)² → 16 + 4 + 64 → 84 → 8 × 4 → 32
In the same way-
312 → (3)² + (1)² + (2)² → 9 + 1 + 4 → 14 → 1 × 4 → 4

The logic is:
Badminton: shuttlecock - Shuttlecock is a lightweight conical object with a rounded often rubber-covered nose that is used in badminton.
Similarly,
Snooker: → A billiard ball is a small, hard ball used in cue sports, such as carom billiards, pool, and snooker.

We can draw the following family tree with the given information,

So, Kamal is the brother of the woman.

His manager terminates J from his job.
(A) Terminate J from his job.
This is the most suitable option as per the given condition. Since it was a first offence of the employee so the manager can either dismiss the employee, impose a large fine or give a written warning. So as per his offence, this action can be taken by the manager.
(B) Impose a fine of Rs. 5 on J.
This is not a suitable option. Imposing Rs. 5 fine is not a large fine, so the manager can't take such action.
(C) Call for a meeting and congratulate his behaviour.
This is not a suitable option. Since it was first offence of the employee so the manager can either dismiss the employee, impose a large fine or give a written warning. Congratulating him means the manager is favoring him on his mistakes, which is unacceptable.
(D) Call J over the phone and warn him.
This is not a suitable option. Since it was the first offence of an employee so the manager can either dismiss the employee, impose a large fine or give a written warning. Calling J over the phone means not taking action as per rules.

Given equation is,
63 ÷ 21 - 42 + 8 × 7 = 135
Interchanging numbers and applying BODMAS rule option wise,
(I) 63 ÷ 21 - 42 + 8 × 7 = 135
Interchanging 21 and 42
63 ÷ 42 - 21 + 8 × 7 = 135
1.5 - 21 + 8 × 7 = 135
1.5 - 21 + 56 = 135
1.5 - 35 = 135
-33.5 ≠ 135
(II) 63 ÷ 21 - 42 + 8 × 7 = 135
Interchanging 21 and 8
63 ÷ 8 - 42 + 21 × 7 = 135
7.875 - 42 + 21 × 7 = 135
7.875 - 42 + 147 =135
7.875 + 105 = 135
112.875 ≠ 135
(III) 63 ÷ 21 - 42 + 8 × 7 = 135
Interchanging 7 and 63
7 ÷ 21 - 42 + 8 × 63 = 135
0.33 - 42 + 8 × 63 = 135
0.33 - 42 + 504 = 135
462.33 ≠ 135
(IV) 63 ÷ 21 - 42 + 8 × 7 = 135
Interchanging 7 and 21
63 ÷ 7 - 42 + 8 × 21 = 135
9 - 42 + 8 × 21 = 135
9 - 42 + 168 = 135
9 + 126 = 135
135 = 135.
Hence. the correct option is (D).

According to the given information:

So, Mina is facing the North-West direction.

The pattern is as follows:
L A C K = 12 × 1 × 3 × 11 = 396
Similarly,
B A C K = 2 × 1 × 3 × 11 = 66

The correct mirror image of the question figure is shown below:

From the given information,
(I) Z is sitting one of the corner and he is sitting third to the right of X, who is facing south direction, there will be only condition by which we can place both X and Z.

(II) V is the neighbor of Z and V is sitting third to the left of N who is facing North direction. So according to the given condition N will sit just left of X, because from there only V will be third to left of N.

(III) C is sitting second to the right of B. So in the row there is only place for B and C because no other place satisfy the condition of B and C. Here B will face South direction because if B is facing North then it will not satisfy the condition of C is second right to B because in this condition B will be near to N who is already facing North. This will contradict the given condition of neighbor facing opposite direction.

(IV) P is not near to B so P will sit between V and X. Remaining one person M will sit between C and B.

(V) All the people are placed in the row now we have decide their direction according to the given condition which is People sitting near to each other are facing opposite.
(VI) Here M will face opposite to B so M will be in North then C will face opposite to M so C will be in South direction.
(VII) P will face opposite of X so P will be in North direction same as V will opposite to P then V will face South direction and in final Z will face opposite to V so Z will be facing in North direction.

This is the final arrangement.
So, C is sitting third to the right of P.

From the given information,
(I) Z is sitting one of the corner and he is sitting third to the right of X, who is facing south direction, there will be only condition by which we can place both X and Z.

(II) V is the neighbor of Z and V is sitting third to the left of N who is facing North direction. So according to the given condition N will sit just left of X, because from there only V will be third to left of N.

(III) C is sitting second to the right of B. So in the row there is only place for B and C because no other place satisfy the condition of B and C. Here B will face South direction because if B is facing North then it will not satisfy the condition of C is second right to B because in this condition B will be near to N who is already facing North. This will contradict the given condition of neighbor facing opposite direction.

(IV) P is not near to B so P will sit between V and X. Remaining one person M will sit between C and B.

(V) All the people are placed in the row now we have decide their direction according to the given condition which is People sitting near to each other are facing opposite.
(VI) Here M will face opposite to B so M will be in North then C will face opposite to M so C will be in South direction.
(VII) P will face opposite of X so P will be in North direction same as V will opposite to P then V will face South direction and in final Z will face opposite to V so Z will be facing in North direction.

This is the final arrangement.
So, X is sitting second to right of C.

From the given information,

Breaking the statement –
N is M's daughter's father's mother's son

Hence, N is the brother of M's husband.

Given : 
R A M S T
1 2 3 4 5
By checking options:
(1) 32514 → MATRS
(2) 13245 → RMAST
(3) 25431 → ATSMR
(4) 43215 → SMART
Only option (4) 43215 forms the meaning word i.e., SMART.
Hence, 43215 is the correct order.

• Preparing the family tree using the following symbols:
  

1) Rohan is Sumit's brother. 

2) Sumit wants to marry Sujata.

3) Sujata is the daughter of Hari Chand.
4) Rohan wants to divorce Sunita.
4) Sujata and Sunita are sisters.

• The family tree will be as follows:
  
• Here, Harichand is either mother-in-law or father-in-law of Rohan.
• Because mother-in-law is not given in the options, Harichand is the father-in-law of Rohan.

Hence, 'father-in-law' is the correct answer.

The logic followed here is :-
Second number = First number2 + (First number × 2)
1) 19 ∶ 324 → 192 + (19 × 2) = 361 + 38 = 399 ≠ 324
2) 5 ∶ 35 → 52 + (5 × 2) = 25 + 10 = 35
3) 7 ∶ 63 → 72 + (7 × 2) = 49 + 14 = 63
4) 13 ∶ 195 → 132 + (13 × 2) = 169 + 26 = 195
Here, 19 : 324 is different from other three alternatives
Hence, the correct answer is "19 ∶ 324".

The positional values of English alphabet is as follows:

The pattern followed here is as follows:
'HOME' is written as 'LROF'

'EYE' is written as 'HAF'

'SO' is written as 'UP'

Similarly, 
'HOUSE' will be written as:

Hence, MSXUF is the correct answer.

The Logic here is as follows:
In Figure 1:

⇒ 4 - 1 = 3
⇒ 8 - 2 = 6
And 3 x 6 = 18 (middle term)
In Figure 2:

⇒ 4 - 2 = 2
⇒ 9 - 5 = 4
And 2 x 4 = 8 (middle term)
Similarly,
In Figure 3:

⇒ 8 - 4 = 4
⇒ 9 - 3 = 6
And 4 x 6 = 24 (middle term)
Hence, the correct answer is "24".

The figure that will complete the pattern is shown below:

Hence, option figure (2) is the correct answer.

The embedded part of this image is.


Hence, the correct answer is "Option 3".

The codes have been assigned as follows,
PERSON →

SHARE →

HERO →

The coded number is 8246.
Hence, "8246" is the correct answer.

Persons : Unknown , Facing towards ccentre.
1. P sits second to the left of T.
2. M is an immediate neighbour of P and S.

3. J sits second to the left of S.
4. One person sits between T and J.

The above arrangement will be the final arrangement.
Hence, 8 persons are sitting around the table.

The logic followed here is 

The pattern in the given series is:
Here the first two characters are interchanged in every step and the rest two are increased by 2 positional value.
 By following the pattern the next step will be:
                                                                        
Here we get NHQW.
Hence, the correct answer is NHQW.

The logic followed here is:
In all the pairs, the 1st word is a place where the 2nd word is found or 1st word is meant for 2nd word i.e.
Option (2) Garage - Car → Garage is a place for the maintaining or repairing cars.
Option (3) Dispensary - Medicine → Dispensary is a place where Medicines are kept for purchase or sale.
Option (4) Hospital - Patient → Hospital is a place for the treatment of patient.
But in Option (1) Lawyer – Court → Here 1st word (i.e. Lawyer) is not a place for keeping 2nd word (i.e. Court) but vice versa is true.
Thus, “Lawyer – Court” is the odd pair.

Given,
Percentage of the student present in the school = 90 %
Number of students who are absent = 20
Let, the total number of students in the school is x.
According to the question,
((x×90)/100)+20 = x
⇒ 90x = 100x−2000
⇒ 10x = 2000
⇒ x = 200

Let the length and breadth of the field be ‘l’ m and ‘b’ m respectively.
According to the question, the length of the field is 3 m more than twice the breadth
⇒ l = (2b + 3) m
We know that,
Perimeter of a rectangular field = 2(l + b)
⇒ 84 = 2(2b + 3 + b)
⇒ 84/2 = 3b + 3
⇒ b = 39/3 = 13 m
∴ b = 13 m
l = 2b + 3 = 2 × 13 + 3 = 29 m
∴ l = 29 m

Given-
Marked price of the article (MP)=  Rs. 1000
First discount (D₁) = 10%
Second discount (D₂) = 20%
Third discount (D₃) = 30%
According to the formula-

[where SP is selling price of the article]

The selling price of the article is Rs. 504.

Let (17)^3.5 × (17)^x = 178
Then, (17)^3.5+x = 178
∴ 3.5 + x = 8
⇒ x = (8 - 3.5)
⇒ x = 4.5

Since first and second varieties are mixed in equal proportions, so their average price 
So, now the mixture is formed by mixing two varieties, one at Rs. 130.50 per kg and the other at say Rs. '�' per kg in the ratio 2:2,
i.e., 1 : 1
We have to find 'x'
