Direction: Read the following passage carefully and answer the questions. Your answer to these questions should be based on passage only.
PM's offensive and pompous reply verged on the preposterous. It is not only in consonance with certain facts, but is also wholly out of keeping with disappointment for them that a government and people noted for their high culture and politeness should have committed this serious lapse and should have addressed the GOI in a language which is discourteous and unbecoming, even if it were addressed to a hostile country. Since it is addressed to a country that is referred as friendly, this can only be considered as an act of forgetfulness. The GOI realizes that the system of government in China is different from that prevailing in India. It is the right of the Chinese people to have a government of their choice, and no one else has a right to interfere

WB Police Constable Mock Test - 9 - Question 3

Direction: Read the following passage carefully and answer the questions. Your answer to these questions should be based on passage only.
To be able to grow into self-confident, fearless, and active women, a girl must be nurtured in an atmosphere where she can be valued. However, for the average girl child in India, her prospects of all-round healthy development are severely constrained. Born into a socially inhospitable environment, a girl is considered to be an expense - someone who will never contribute to the family income and at the time of her marriage will take large assets as dowry. So deeply entrenched is the ideology of son preference, that a mother not only hopes and prays for a boy but actually fears the birth of a daughter. In India, girls are socialized from the very beginning to accept the ideology of male supremacy, which makes them a prey to discriminatory practices. This means that not only are girls socially unequipped to question the injustices done to them, but in the absence of models of role and conduct, they actually propagate the dominant social and cultural values which are against their interests. A large number of girls are allowed to die because of malnutrition and disease, which are not properly treated. Children who are working and are on the street are known as street children. A street child may be defined as a minor for whom the street has become his or her habitual abode and who is without adequate protection.

Q. Do the girls really live their lives in their own terms?

WB Police Constable Mock Test - 9 - Question 4

Direction: Read the following passages carefully and answer the question that follows.
Regardless of how the state's feedback control law is designed, it is almost always necessary to implement it, using estimates of the state obtained from an observer. Hence, it is necessary to insure so that the desirable properties of the state feedback design do not vanish when the state estimate are used. It is proven in linear system theory courses that the command response is unaffected by the presence of the observer. However, the response to initial conditions will affect the system output. It is suggested that the observed poles should be made faster than the state feedback poles by an amount that depends upon the level of measurement noise. These conclusions are generally based upon transient time response properties of the system, and not on feedback properties such as robustness margins, We now present a procedure for tuning an observer so that, under appropriate conditions, the feedback properties of a state feedback design are recovered.

Q. On what basis suggestions are given?

Detailed Solution for WB Police Constable Mock Test - 9 - Question 4

The author says that suggestions are given on the basis of transient time response properties.

WB Police Constable Mock Test - 9 - Question 24

Direction: Study the following information and answer the given questions carefully.

Ishu was standing in a park. She walked 6m towards the east and turned right and walked 3m. Then she turned left and walked 6m to reach the mall. Now, she turned right and walked 4m and again turned right and walked 3m to reach the gym. After some time, she turned left and walked 3m and turned right and walked 9m to reach his school.

Q. What is the direction of the gym with respect to the park?

Detailed Solution for WB Police Constable Mock Test - 9 - Question 24

From the common explanation, we can see that the gym is in the south east direction of the park.
Hence, Option D is correct.
Common Explanation:
References:
Ishu was standing in a park.
She walked 6m towards the east and turned right and walked 3m.
Then she turned left and walked 6m to reach the mall.
Now, she turned right and walked 4m and again turned right and walked 3m to reach the gym.
After some time, she turned left and walked 3m and turned right and walked 9m to reach his school.
Inferences:
From the above statement, we get the final figure below:

WB Police Constable Mock Test - 9 - Question 25

Ayush starts from his house and moves towards South. He walks 100m, then turns left and walks 200m, turns right and walks 500m. How far is he from his house?

Detailed Solution for WB Police Constable Mock Test - 9 - Question 25

We can solve this problem using the Pythagorean theorem.

First, let's break down Ayush's movements:
1. He walks 100m south.
2. He turns left (which means he is now facing east) and walks 200m.
3. He turns right (which means he is now facing south again) and walks 500m.

Now, let's determine his horizontal (east-west) and vertical (north-south) displacements.

Horizontal displacement:
Ayush only moved horizontally during step 2, where he walked 200m east. Therefore, his total horizontal displacement is 200m.

Vertical displacement:
Ayush moved vertically during steps 1 and 3. In step 1, he walked 100m south, and in step 3, he walked 500m south. Therefore, his total vertical displacement is 100m + 500m = 600m.

Now we can use the Pythagorean theorem to calculate the distance between his starting point (his house) and his final position:

Distance = √(horizontal displacement^2 + vertical displacement^2)
Distance = √(200m^2 + 600m^2)
Distance = √(40,000m^2 + 360,000m^2)
Distance = √(400,000m^2)
Distance = 200√10m

So the correct answer is 3 (200√10m).

WB Police Constable Mock Test - 9 - Question 27

Six persons – Veer, Prakash, Bhola, Shiv, Ankur and Bhanu were sitting around a circular table facing towards the centre. Who was sitting to the immediate right of Bhanu?

Statement I: Ankur was sitting second to the right of Veer, who was sitting to the immediate left of Bhola. Prakash was sitting second to the left of Bhola.
Statement II: Shiv was sitting to the immediate right of Ankur, who was sitting second to the right of Veer. Prakash was sitting second to the left of Bhola, who is to the immediate left of Ankur.

Detailed Solution for WB Police Constable Mock Test - 9 - Question 27

Checking Statement I:
Using the above references, we get the following arrangement:

Since there is no information about the position of Bhanu so we cannot find the person who sits on the immediate right of Bhanu.

Hence, data in statement I alone is not sufficient.
Checking Statement II:
Using the above references, we get the following arrangement:

Clearly, Prakash sits on the immediate right of Bhanu.

Hence, data in statement II alone is sufficient.

Hence, Option B is correct.

WB Police Constable Mock Test - 9 - Question 28

Who is oldest among Priya, Kamal, Johny, Rohit, Suresh and Tinku?

Statement I: Rohit is older than Priya and Johny. Rohit is younger than Kamal. Suresh is older than only Tinku.

Statement II: Suresh is older than Johny but younger than Priya. Tinku is older than only Rohit. Priya is not the oldest.

Detailed Solution for WB Police Constable Mock Test - 9 - Question 28

Checking Statement I:

Using the above references, we get the following arrangement:

Kamal > Rohit > Priya/Johny > Suresh > Tinku

Clearly Kamal is the oldest among all.

Hence data in statement I is sufficient to answer the question.

Checking Statement II:

Using the above references, we get the following arrangement

Kamal > Priya > Suresh > Johny > Tinku > Rohit

Clearly Kamal is the oldest among all.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

WB Police Constable Mock Test - 9 - Question 29

Directions: Each of the following consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:

What is rank of Rhea from bottom in a class of 30 students?
Statement I:
Harshita is 22nd from the top and ranks 13 below Akansha, whose rank is 5 above Rhea.
Statement II: Yamini is 19th from the bottom. 13 persons are between Yamini and Rhea.

Detailed Solution for WB Police Constable Mock Test - 9 - Question 29

From Statement I:

From this statement, we get the following ranking.

Person in the row = 8 persons + Akansha + 4 persons + Rhea + 7 persons + Harshita + 8 persons

So, we get that Rhea is 17th from the bottom in the class.

Clearly, Statement I alone is sufficient to answer the question.

From Statement II:

From this statement, we get the following ranking.

Person in the row = 11 persons + Yamini + 13 persons + Rhea + 4 persons

So, we get that Rhea is 5th from the bottom in the class.

Clearly, Statement II alone is sufficient to answer the question.

Clearly, Either Statement I or Statement II alone is sufficient to answer the question.

Hence, option C is the correct answer.

WB Police Constable Mock Test - 9 - Question 30
