$$(18-45), (16-40), (14-28), (8-20)$$

A
$$18-45$$

B
$$16-40$$

C
$$14-28$$

D
$$8-20$$

Solution

In all other pairs, 2nd number =1st number $$\times$$ 2.5.
Question 3
1 / -0

$$E$$ is the son of $$A$$.
$$D$$ is the son of $$B$$.
$$E$$ is married to $$C$$.
$$C$$ is $$B$$'s daughter.
How is $$D$$ related to $$E$$ ?

B
Uncle

C
Father-in-law

D
Brother-in-law

E
None of these

Solution

$$C$$ is $$B$$'s daughter and $$D$$ is $$B$$'s son.
So, $$D$$ is the brother of $$C$$.
$$E$$ is a male married to $$C$$. So, $$E$$ is the husband of $$C$$, whose brother is $$D$$.
So, $$D$$ is the brother-in-law of $$E$$.
option D.

Find the odd one out:

A
$$140$$

B
$$221$$

C
$$321$$

D
$$437$$

E
$$667$$

Solution

$$\textbf{Step 1: Check for some mathematical relation with number/digits.}$$

$$\text{Except 667 all others are consecutive terms of a sequence, }$$
$$(A)\ \ 140=12^2-4$$
$$(B)\ \ 221=15^2-4$$
$$(C)\ \ 321=18^2-4$$
$$(D)\ \ 437=21^2-4$$
$$(E)\ \ 667\neq 24^2-4$$
$$\text{Thus, option E does not follow the given pattern.}$$

$$\textbf{Hence, option E is correct.}$$

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 prefectly 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 a 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 his birth, the child automatically becomes the member of his 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.

Any class B female can have
(P). Grandfather born in class A
(Q). Grandmother born in class A

A
Only (P) can be true

B
Only (Q) can be true

C
Either (P) or (Q) can be true

D
Neither (P) and (Q) can be true

E
Both (P) and (Q) can be true

Solution

The mother of class B female belongs to class B.
So, her father was born in class A.
Thus, her father's mother belonged to class A, and father's father was born in class B.
So, the Grandfather belongs to class B and Grandmother belongs to class A.
option B.
Question 8
1 / -0

Vasant says, " I have as many sisters as brothers."
Vaishali says, "Each of us sisters has only half as many sisters as brothers. "
Assuming that Vasant and Vaishali are brother and sister, how many brothers and sisters are there in the family ?

A
$$8$$ brothers and $$6$$ sisters

B
$$6$$ brothers and $$5$$ sisters

C
$$5$$ brothers and $$4$$ sisters

D
$$4$$ brothers and $$3$$ sisters

Solution

Let no. of brothers be $$x$$ and no. of sisters be $$y$$.
As Vasant says:
$$x - 1 = y$$
as Vaishali says:
$$x/2 = y - 1$$
Solving both equations,
we get $$x = 4$$ and $$y = 3$$
So, there are $$4$$ brothers and $$3$$ sisters in the family.
option $$D$$.
