CRPF Head Constable Mock Test - 2 - CDS MCQ

MP, MLC and MLA are political positions whereas the Registrar is not.
MP, MLA and MLC are related to politics, Registrar related to administration. So registrar is odd one out.

Conclusions:
I. Some silver are ring → True as per the venn diagram.
II. No ring is silver → False as this is not possible as shown in the diagram.
Thus, only conclusion I follows.

The pattern followed is:
1st quadrant: 2² = 4
2nd quadrant: 2³ = 8
4th quadrant: 2⁵ = 32
So, 3rd quadrant: 2⁴ = 16

Considering dice 1st and 4th
The opposite match of the given numbers is:
3 2 6
3 1 5
The missing number is the opposite number to 3 i.e. 4

The logic is:
(D) ANIMATED → EXAMINATION → cannot be formed as there is no D.
(A) MAINTAIN → EXAMINATION → can be formed.
(B) TOXIN → EXAMINATION → can be formed.
(C) MENTION → EXAMINATION → can be formed.
So, 'ANIMATED' is the correct answer.

The symbol and its meaning is as follow:

According to the given information:

From the diagram, it is clear that B is the son of D.

Given,
On sports day in a school, 8 students took part in a race. They were all made to stand in a straight line. Sumit was standing 5th from the right end and there are 3 students standing in between Sumit and Ritesh.
As we can see, 

Thus, the rank of Ritesh from the left end of the line is 8th.

Rahim's Movement:

Therefore, the distance of Rahim from his starting point,
= 20 + 25
= 45 meters

The pattern followed here is:
BOUND → 2+15+21+14+4 = 56 → 56×2 = 112
WHITE →  23+8+9+20+5 = 65 → 65×2 = 130
So, 130 will be code of WHITE in same language.

(A) 12 and 48
Given expression: 12 × 2 + 8 - 48 ÷ 6 = 20
After replacing the numbers we get:
L.H.S = 48 × 2 + 8 - 12 ÷ 6
= 96 + 8 – 2
= 104 – 2
= 102 ≠ R.HS
(B) 6 and 8
Given expression: 12 × 2 + 8 - 48 ÷ 6 = 20
After replacing the numbers we get:
L.H.S = 12 × 2 + 6 - 48 ÷ 8
= 24 + 6 – 6
= 30 – 6
= 24 ≠ R.HS
(C) 8 and 12
Given expression: 12 × 2 + 8 - 48 ÷ 6 = 20
After replacing the numbers we get:
L.H.S = 8 × 2 + 12 - 48 ÷ 6
= 16 + 12 – 8
= 28 – 8
= 20 = R.H.S
(D) 2 and 6
Given expression: 12 × 2 + 8 - 48 ÷ 6 = 20
After replacing the numbers we get:
L.H.S = 12 × 6 + 8 - 48 ÷ 2
= 72 + 8 – 24
= 80 – 24
= 56 ≠ R.HS
Therefore, ‘8 and 12’ is the correct answer.

1) B sits fourth to the right of A.
2) E sits second to the right of A.
3) D is the immediate left of E. 

4) D sits third to the right of C. 
5) Two persons sit between F and G.
6) G does not sit second to the left of D. 
So, the final arrangement is:

So, E sits second to the left of B.

1) B sits fourth to the right of A.
2) E sits second to the right of A.
3) D is the immediate left of E. 

4) D sits third to the right of C. 
5) Two persons sit between F and G.
6) G does not sit second to the left of D. 
So, the final arrangement is:

So, B sits exactly between G and C.

The logic is:
S + 2 = U; U opposite F,
A + 2 = C; C + 2 = E,
O + 2 = Q; Q opposite J,
I + 2 = K; K opposite P,
So, ACE is the odd one out.

The logic followed here is :-
The alphabet positional value of consonant is multiplied with ×2.
The alphabet positional value of vowel is added with +4.
'INTENT' is written as '9284052840'.

And
'ONLINE' is written as '1528249289'. 

Similarly,
'REWARD' will be written as :

Hence, the correct answer is "369465368".

The image obtained when the paper is unfolded is,

Hence, option 3 is the correct answer.

The least possible Venn diagram for the statements is as below:-

Conclusion:
1. Some thieves are boys 
Explanation:- As there is direct relation between boys and thieves.
2. All thieves are boys 
Explanation:-  As there is not 100% relation between boys and thieves.
Hence, the correct answer is only conclusion 1 is true.

The logic followed here is:

Hence, 'VE' is the correct answer.

Given : [{(38 × 23) - (4 ÷ 3)} + (6 - 3)] ÷ 2

So, after interchanging the signs :
⇒ [{(38 - 23) + (4 × 3)} ÷ (6 + 3)] × 2
⇒ [{15 + 12} ÷ (6 + 3)] × 2
⇒ [27 ÷ 9] × 2
⇒ 3 × 2
⇒ 6
Hence, "6" is the correct answer.

→REPRESENT→RAPPROCHEMENT, S is not there in the given word.
→REPROACH→RAPPROCHEMENT, all words occur in the given word.
→PHANTOM→RAPPROCHEMENT, all words occur in the given word.
→CEMENT→RAPPROCHEMENT, all words occur in the given word.
→So, REPRESENT cannot be formed.
Hence, the correct answer is "REPRESENT".

The correct Venn diagram representation is 

• Some Indians are Black hair people.
• Some Taller are Indians.
• Some Black haired people are Taller.

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

According to the given information:
Step 1: Reema starts from her house and cycles 4 km towards the west and then turns right and cycles 6 km.

Step 2:  She again turns right and cycles for X km to reach her school. Point A is to the south of her school and also 2 km to the west of her house.

So the value of X is:
X = 4 - 2 
X = 2km
Hence the correct answer is option (3).

The logic followed here is that in question figure there is:
i) a hexagon
ii) three inter crossing arrows within the hexagon,
iii) two vertical lines within the hexagon
iv) a circle within the hexagon.
The answer figure C is having all these elements.

Hence, figure C bears the closest resemblance to the following figure.

The logic followed is 
In all the numbers except option (2), the difference between the second number and the first number is 13. 
Option 1. 56-69 
(56 - 69) = 13 
Option 2. 64-73 
(73 - 64) = 9 
Option 3. 34-47 
(47 - 34) = 13 
Option 4. 23-36 
(36 - 23) = 13 
Hence the correct answer is "Option 2".

A watch reads 4.30. If the minute hand points East, then the hour hand will point at North-East direction, as shown below:

Hence, 'North-east' is the correct answer.

Given:
56 : 616 :: 45 : ? :: 79 : 1264 
Logic:
The second number = First number × (First digit of first number + Second digit of first number)
As per the given information:
In 56 : 616 →
The second number = First number × (First digit of first number + Second digit of first number)
⇒ 616 = 56 × (5 + 6)
⇒ 616 = 56 × 11
⇒ 616 = 616
In 79 : 1264 →
The second number = First number × (First digit of first number + Second digit of first number)
⇒ 1264 = 79 × (7 + 9)
⇒ 1264 = 79 × 16
⇒ 1264 = 1264
Similarly,
In 45 : ? →
The second number = First number × (First digit of first number + Second digit of first number)
⇒ ? = 45 × (4 + 5)
⇒ ? = 45 × 9
⇒ 405
Hence, the correct answer is "405".

Given:
CP (Cost price) of 70 article = Rs. 890
SP (Selling price) of 60 article = Rs. 890

CP of 70 article is 890
⇒ CP of 420 article = Rs. 5340
⇒ SP of 60 article = 890
⇒ SP of 420 article = Rs. 6230
Profit = 6230−5340 = Rs. 890
∴ Profit % = (890/5340) x 100 = 16(2/3)%

2 L of the solution is removed remaining solution will be 5-2 =3 L
The amount of alcohol in 3 liters of solution,
(20/100) x 3  = 3/5
After adding 2 L of water amount of solution become 5 L but with different strength.
We have 5 L of the solution in which 3/5 Lis alcohol
% of alcohol in 5 L solution % = 

We know that,
Time taken = 1/rate of work
Therefore, according to the question,

∴ A alone will do that work in 120 days.

Given,
(a−b):(a+b) = 1:5
As we know,

Let a−b = x

Mother’s age (M) + daughter’s age (D) = 50 years.
Mother’s age (M)– daughter’s age(D) = 30 years
Adding both the above equation,
⇒ 2 M = 50 + 30 = 80
⇒ M = 40 years
