The transfer function of a real system, H(s), is given as :
 

where A, B, C and D are positive constants. This system cannot operate as 

Detailed Solution for MAHATRANSCO AE Electrical Mock Test - 1 - Question 1

At low = freq. (s = 0)

H(0) = B/D

  At high - freq. (s = ∞)

H(∞) = 0

Since, H(∞) should be non-zero for HPF. So, the above system cannot be operated as HPF because for high pass filter should pass high-frequency component i.e H(∞) should be non-zero.

Directions: Read the following information carefully and answer the question that follows.

In a village of Bastar district in Madhya Pradesh, only two types of people live who belong to a tribal class. The first type is known as class A, while the other is known as class B. In that village, there is no other type of person except these two. The activities of both types of people are governed by perfectly patterned norms of social behaviour. Each person of the tribe has to obey the norms. They are rigid about this.

As far as marriage is concerned, the following norms are to be followed:
(A) The people of class A cannot marry any other member of their own class, though they can marry members of class B.
(B) After being married, each male member ceases to be member of that class in which he was born, but automatically he becomes the member of the other class to which his wife belongs.
(C) As far as females are concerned, they remain the members of their own class after being married.
(D) On its birth, the child automatically becomes the member of its mother's class.
(E) When any male member becomes widower or divorcee, then he again belongs to the group in which he was born.
(F) Nobody can marry more than one person according to social laws.

Q. A boy who was born in class B (boy and his wife both can have married and unmarried brothers) can have
Detailed Solution for MAHATRANSCO AE Electrical Mock Test - 1 - Question 14

The boy born in class B will marry a girl of class A. So, the daughter will belong to class A. Thus, (1) is false.
Since the boy's daughter will belong to class A, she would marry a boy of class B and so the son-in-law would be from class B. So, (2) is false.
The boy, born in class B, will have mother born in class B and father born in class A. So, his uncle (i.e. mother's brother or father's brother) can be from class A or B.
So, (3) is true.
The boy in class B gets married to a girl in class A and himself becomes of class A.
Their son also belongs to class A, who will marry a girl of class B and himself becomes of class B.
When the son divorces, he reverts to his original class, i.e. A; hence, (4) is false.

Directions: Study the information given below and answer the question that follows.

A is the father of two children, B and D, who are of different sexes.
C is B's spouse.
E is of the same sex as D.
B and C have two children: F, who is of the same sex as B and G, who is of the same sex as C.
E's mother H, who is married to L, is the sister of D's mother, M.
E and E's spouse, I, have two children J and K, who are of the same sex as I.
No person has married more than once, and no children have been born out of wedlock.
The only restriction on marriage is that marriage to a sibling, to a direct descendant, or to more than one person at the same time is forbidden.

Q. According to the rules, D can marry
Detailed Solution for MAHATRANSCO AE Electrical Mock Test - 1 - Question 15


We can draw the above diagram based on the information given in the question. If the gender of the person is known, it is denoted by the suffix m or f. If it is not known, then it is denoted by x or y. We know, for example, that G is of the same sex as C, so we can label both as x; B and therefore, F are of the opposite sex from C, so we can label both y, and so on. Horizontal lines indicate marriage, vertical or diagonal lines indicate children. 
D is an x, and can therefore, marry any unmarried y. So, he can marry F, J, or K. 
Hence, answer option (1) is correct.

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 MAHATRANSCO AE Electrical Mock Test - 1 - Question 19

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)

The average of a batsman after 25 innings was 56 runs per innings. If after the 26th inning his average increased by 2 runs, then what was his score in the 26th inning? 
Detailed Solution for MAHATRANSCO AE Electrical Mock Test - 1 - Question 27

Normal process:
Runs in 26th inning = Runs total after 26 innings – Runs total after 25 innings
= 26 X 58 – 25 X 56

For Easy calculation use:

= (56 + 2) X 26 – 56 X 25 )
= 2 X 26 + (56 X 26 – 56 X 25)
= 52 + 56 = 108

Since the average increases by 2 runs per innings, it is equivalent to 2 runs being added to each score in the first 25 innings. Now, since these runs can only be added by the runs scored in the 26th inning, the score in the 26th inning must be 25 X 2 = 50 runs higher than the average after 26 innings (i.e. new average = 58).

Hence, runs scored in 26th inning:
= New Average + Old innings X Change in average

= 58 + 25 X 2
= 108
