CISF Head Constable Mock Test - 3 - CDS MCQ

On counting the number of triangles in the given figure we find that there are 11 triangles in the given figure.

The logic followed here is:-
'Saliva' is secreted by 'Salivary Glands'.
Similarly,
'Gastric Juice' is secreted by 'Stomach'.

Given:
Five years ago, the ages of Deepak and Sumit were in the ratio 3 : 4.
Current age of Deepak is 26 years.
Suppose the ages of Deepak and Sumit were 3x and 4x respectively 5 years ago.
Current age of Deepak is 26 years.
So,
(3x + 5) = 26
⇒ x = 7
Hence, age of Sumit after 6 years = 7 × 4 + 5 + 6 = 39 years
∴ The age of Sumit after 6 years is 39 years.

P, Q, R, S, T, U, V, and W are the eight people sitting around a circular table facing the center. 
1) T is sitting second to the left of S.
(As it is a circular arrangement, we can randomly pick a seat for S and then place T accordingly.)

2) P is sitting third to the right of R.
3) P is an immediate neighbor of T.
(Implies, P is either sitting to the left of T or to the right of T. There will be two cases based on the position of P as shown in the image below.)

4) R is not sitting opposite S.
(Implies, case II is wrong.)
5) V is sitting opposite Q.
(Implies, either V or Q is sitting between T and S and the other person is sitting on the opposite seat.)
6) Q is sitting to the immediate left of U.
(Implies, U is sitting opposite S and Q is sitting to the immediate right of R. Also, now that we know that Q is sitting to the immediate right of R, V is sitting between T and S. Now, that only W is left to be placed, we can place him to the immediate right of S as it is the only seat available.)

Clearly, R is sitting opposite T.

P, Q, R, S, T, U, V, and W are the eight people sitting around a circular table facing the center. 
1) T is sitting second to the left of S.
(As it is a circular arrangement, we can randomly pick a seat for S and then place T accordingly.)

2) P is sitting third to the right of R.
3) P is an immediate neighbor of T.
(Implies, P is either sitting to the left of T or to the right of T. There will be two cases based on the position of P as shown in the image below.)

4) R is not sitting opposite S.
(Implies, case II is wrong.)
5) V is sitting opposite Q.
(Implies, either V or Q is sitting between T and S and the other person is sitting on the opposite seat.)
6) Q is sitting to the immediate left of U.
(Implies, U is sitting opposite S and Q is sitting to the immediate right of R. Also, now that we know that Q is sitting to the immediate right of R, V is sitting between T and S. Now, that only W is left to be placed, we can place him to the immediate right of S as it is the only seat available.)

Clearly, five people are sitting between R and U if we start from R and go towards clockwise direction.

The study of butterflies is known as Lepidopterology. Similarly, the study of maps is known as Cartography.

Answer figure (A) in which question figure is hidden/embedded.

The most appropriate thing to do when we buy a bottle of packed water on a street and end up emptying the bottle would be will keep the bottle and dispose in a garbage bin as this is the only right way of protecting our environment and keeping it clean.

According to the question, we will draw the following figure to find the direction from the starting point.

The distance between Deepak and starting point = PT
PT = PS+ST
PT = 15m + 10 m
PT = 25 m
And, T is to the East of P.

Given figure,

After rotating it 90 degree clockwise, we get

The diagram according to the question,

Therefore, from the above family tree, the person in the photograph is the grandson of X.

Let the number of boys be x.
Then,

If total number of students is y.
Then,

Therefore, number of girls in the class = (36 - 24) = 12.

The logic followed here is:
By using BODMAS
 
And interchanging alphabets with the signs,

Given equation :- (84 D 6) B 7 A (22 B 4) C 16 A (15 B 8) = ? 
(84 ÷  6) ×  7 + (22 ×  4) - 16 + (15 ×  8) = ? 
14 × 7 + 88 - 16 + 120 = ?
98 + 88 - 16 + 120 = ?
306 - 16 = ?
290 = ?
Hence, ? will be replaced by 290.

The pattern in the given clusters is:

DUCK becomes FSIE ;

FISH becomes HGUF;
Similarly,
By following the same pattern we get:

FROG becomes HPQE
Hence the correct answer is HPQE.

According to the statement, the least possible venn diagram is:

Conclusions:
i. Some monuments are not stoves.→ All stoves are helipads and All monuments are helipads.→ Not Follows.
II. Some binoculars may be stoves is a possibility.→ All monuments are helipads and All stoves are helipads and Some helipads are binoculars.→ Follows.
so, only statement II Follows.
Hence, the correct option is 2.

The diagram is as follows:

Clearly, Dipesh's son is sit between Dipesh and his wife.
Hence, the correct answer is "Dipesh's son".

Preparing the family tree using the following symbols.

P is the father of M, T is the son of V, Z is the wife of M, Z's father Q is V's husband.

Clearly, we can see that T is Brother of Z.
Hence, the correct answer is "Brother".

Here, the logic followed in the given options is:
(1) 64 → 8²
(2) 196 → 14²
(3) 56 → 7² + 7
(4) 144 → 12²
Here, in digit 56 different logic is followed which means 56 is different from the rest.
Hence, the correct answer is "56".

The logic followed here is,

Similarly,
EI (+6) → KO

Hence, the correct answer is "KO".

The pattern followed here is:
Option 1): Calendar is a list that shows the days, weeks and months of a particular year. calendar itself has no days.
Option 2): Year there are 12 month in a year.
Option 3): Date a specified day is represented by a date.
Option 4): Month the number of days in a month is called a month.
Here, except the calendar, all are represent the days.
Hence, the correct answer is "Calendar".

As per the given options:
Here, the Seed, leaf, and root are the parts of the plant.
That's why Seed, leaf, and root are similar.
Hence, The correct answer is "Plant".

Logic : 

1. First letter → Immediate succeeding letter or (+1)
2. Second letter → 3rd succeeding letter or (+3)
3. Third letter → 5th succeeding letter or (+5)
   ​

Hence, "TSZ" is the correct answer.

The pattern followed here is:
 
Hence, '599' is the correct answer.

The table is alphabets place value:

Given: BAG : DEJ

Similarly,
Option(2): CAB : EEE

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

Given:
Amount = Rs. 605
Rate = 10%
Time = 2 years
Formula used
Amount = Principal[1 + r%]^t 
Where r and t are rate and time respectively
Calculation:
According to question,

∴ Principal is Rs. 500.

Given,
3 men or 5 women can complete the work in 12 days.
Work done by 3 men = Work done by 5 women
1 men = (5/3) × women
Now, 3 men + 7 women = 3 × (5/3) + 7 women = 12 women
As we know,

Given:

∴ The value of ? is 311.

Given:
A sum of money becomes 27 times in 3 years,
Concept used,
Compound interest,
Calculation:
Ratio of principal to Amount

AS we know,

⇒ Rate = 200%

Given:

∴ The value of ? is 6.
