Find the pairs of consecutive even positive integers both of which should be less than 10 and their sum is greater than 11?

Detailed Solution for Assam Police SI Mock Test - 1 - Question 9

Let x be the smaller of the two consecutive even positive integers, then the other even integer is x + 2. 
 Given x < 10  and x + (x + 2) > 11.  
⇒ x < 10, and 2x + 2 > 11.  
⇒ x < 10, 2x > 9 
⇒ x < 10, x > 9/2 
⇒  x > 9/2   and    x<10 
∴ the required parity even integers is (6, 8)

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

Assam Police SI Mock Test - 1 - Question 23

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.

Assam Police SI Mock Test - 1 - Question 24

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 Assam Police SI Mock Test - 1 - Question 24

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

We get many cases of parents complaining that their children lack concentration, get headache and have behavioral problems. This cannot be proved, though. A scientist with ICMR said exposure to radio frequency radiation has a thermal effects, caused by holding a phone close to the body, and also a non-thermal effect which can be attributed to the induced electromagnetic effects inside biological cells.
