CISF Head Constable Mock Test - 2 - CISF Head Constable MCQ

The best possible diagram from the given information is,

‘U is W's husband's brother's wife’ is the correct answer.

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.

Since the gender of K is not defined, K can be either brother or sister of B.

Buses: A, B, C, D, E, F, G and H.
(1) Bus F is second to the right of bus B and both face away from the center.
(2) Bus A is adjacent to bus F but not to bus B.
(3) Bus C is second to the left of bus A. So, bus A faces either towards or away from the center.
(4) Not more than two adjacent buses face in same direction.

(5) Bus E is not adjacent to bus A.
(6) Bus H is immediate left of bus E and both faces towards the center. So, bus H must be adjacent to bus B.
(7) Equal number of buses are facing towards and away from the center.

(8) Bus D faces toward the center and is not parked adjacent to bus A. So, case 2 must be invalid as it contradicts the given statement. Also, bus G must be immediate left of bus A.

All face away from the center except A.
So, bus A is the odd one out. 

After arranging as per the dictionary order, we get:
Greasepaint → Greasy → Greater → Grebe → Grecian
So, the correct option is 3, 5, 2, 4, 1.

There are 12 triangles and names are as follow:
BDE, DCE, CFE, FAE, AEB, BEC, CEA, ABD, ACD, BCF, BFA, ABC

The logic follows here is:
A = 1, B = 2, C = 3, D = 4,…Z = 26
SUN = S →19, U → 21, N → 14 → 192114
Similarly, TIN → T → 20, 1 → 9, N → 14 → 20914
In the same way, THING → T → 20, H → 8, I → 9, N → 14, G → 7 → 2089147.

After dropping all the symbols and numbers, seventh alphabet from the right end is ‘K’ .
A E I O G K P U F T X V
And the second alphabet to its left is ‘O’.
A E I O G K P U F T X V
Thus, O is the second alphabet to the left of the seventh alphabet from the right end.

A+4 = F                                        Similarly, G+4 = L
P+4 = U                                         R+4 = W
P+4 = U                                         I+4 = N
E+4 = J                                          N+4 = S
A+4 = F                                         D+4 = I
R+4 = W
So we can see the pattern that is being followed above. 
Therefore the answer to the problem is LWNSI.

To obtain the decoded word the code is split into two equal parts and letters in 2nd part are prefixed before letters in 1st part.

Therefore, URENAT will be decoded as NATURE.

The given figure:

To complete the figure, we need to add the quadrant which completes the two concentric rhombuses, a 'dot', and the quadrant should complete the two rectangles on the right and bottom edges as shown below

Hence, "option (2)" is correct.

The option figure formed by rotating 90º clockwise direction of the following figure is given below:-

Hence, "option 2" is the correct answer.

The logic followed here is :-

1) TVX

2) GJL

3) BDF

4) PRT

∴ Here, 'GJL' is different from other three alternatives.
Hence, the correct answer is "GJL".

The image not embedded in given figure is as shown below :

Hence, the correct answer is "Option 3".

The pattern followed here is:

According to the alphabetical positions of the letters,

Similarly,

Hence, ‘24281840303650’ is the correct answer.

The figure that replace the given series is as shown below :

• The symbols moves one step anti-clockwise and a new symbol is added from figure to figure.
  

Hence, the correct answer is "Option 2".

The shaded part represents Self-employed who are neither Technicians nor Uneducated.

The letter representing Self-employed who are neither Technicians nor Uneducated  = F
Hence, ‘F’ is the correct answer.

According to the given information the figure is shown below,

On analyzing the above figure we get the person travelled 40 km Southward and 40 km Northward, so the northward and southward distance cancelled out. The person has travelled 25 Km (20 Km + 5 Km) eastward.
Hence, the shortest distance between her bank and her house is 25 Km.

From position first and third position, it is clear that-
'K' is opposite to 'O', as ( J and L ) is common to both of them.
And from second position, 'N' and 'O' can't be opposite to 'M' as they are adjacent to 'M'.
So, either 'J' or 'L' can be opposite to 'M'.
Now, assuming 'L' is opposite to 'N' in second position.
And on rotating second position such that 'O' is at the top, third position can't be obtained as 'M' would be on the front face.
Thus, 'L' is not opposite to 'N' but 'J' is opposite to 'N'.    
And 'L' is on the face opposite to 'M'.
Hence, 'L' is opposite to 'M'.

Check option one by one:
1) 967384215

2) 543217896

3) 963842175

4) 879543126

'POTENTIAL' is a meaningful English word.
Hence, '963842175' is the correct answer.

The Venn diagrams best represent the relationship between - Carnivorous, Frog, Amphibian figures are shown below:

All Frogs are Amphibian and carnivorous. some amphibians are carnivorous.
Hence, ‘option 4’ is the correct answer.

Here, we use the table given below:

Given:
27 - 9 ÷ 4 + 5 × 3 = 14
Checking all the options one by one:
(1) × and - →
27 × 9 ÷ 4 + 5 - 3
Apply BODMAS:
= 27 × 2.25 + 5 - 3
= 60.75 + 5 - 3
= 62.75 ≠ 14 
(2) + and ÷ →
27 - 9 + 4 ÷ 5 × 3
Apply BODMAS:
= 27 - 9 + 0.8 × 3
= 27 - 9 + 2.4
= 20.4 ≠ 14
(3) ÷ and - →
27 ÷ 9 - 4 + 5 × 3
Apply BODMAS:
= 3 - 4 + 15 = 14
= 18 - 4
= 14
(4) ÷ and × →
27 - 9 × 4 + 5 ÷ 3
Apply BODMAS:
= 27 - 9 × 4 + 1.66
= 27 - 36 + 1.66
= -7.34 ≠ 14
Here, by Option (3) we got the correct answer.
Hence, the correct answer is "Option (3)".

Effective discount 
Where x and y are the success rates of discount
Therefore,
Effective discount on 15% and 20% 
Now apply it on 25% and 32%
Effective discount on 25% and 32% = 

Given,
A can do the work in 24 days.
B can do the work in 16 days.
C can do the work in 12 days.
Efficiency = 
LCM of 24,16 and 12 = 48 = Total work
Efficiency of A = 48/24 = 2 units/day
Efficiency of B = 48/16 = 3 units/day
Efficiency of C = 48/12 = 4 units/day
Total efficiency of A, B and C together = (2+3+4) = 9 units/day
Time taken by A, B and C = 48/9 = 16/3 = 5(1/3) days
∴ Time taken if all of them work together is 5(1/3) days.

Given:
The ratio of the present age of Riti and her father = 6:13.
After 4 years the age of her father = double of Riti's age.
Let, her present age is 6x and that of her father is 13x.
After 4 years her age will be (6x+4).
After 4 years her father's age will be (13x+4).
Accordingly,
(13x+4) = 2×(6x+4)
⇒ 13x+4 = 12x+8
⇒ 13x−12x = 8−4
⇒ x = 4
Riti's present age is (6×4) = 24 years
And her father's present age is (13×4) = 52
At the time of her birth, her father's age was (52−24) = 28 years
∴ The age of her father was 28 years at the time of her birth.

According to the question,
Selling price of glass = Rs. 1965
And loss = 25%

If selling price = Rs. 3013

Given:

Quantity of alcohol in 5 liters solution = 20% of 5 liters = 1 liter
Quantity of alcohol removed = 20% of 2 liters = 400 ml
Quantity of alcohol in new solution:
= 1000-400 ml

= 12%

Formula used:
Average = Total sum/Total subjects
Calculation:
Sum of marks = 70 + 50 + 60 + 65 + 75
= 320
Average mark = Total marks/Number of subjects
= 320/5
= 64
Percentage average mark of 320 = (64/320) x 100
= 20%
∴ Percentage average mark of 320 is 20%.
