Intelligence and Critical Reasoning Test - 1

In this question the relation between first and second is:

49 = 4+9 = 13 and 13² = 169

So,

66 = 6+6 = 12 and 12² = 144

Here, the direct meaning must not be taken. It is assumed that mental power is more effective to physical power and these are compared to the pen and sword respectively because the pen is a tool to write down powerful ideas whereas the sword is a tool to show your physical power.

The statement talks about how video gamers are often nimble with their hands than non-gamers. Thus, the assumption I is correct. Again pianists need to have nimble fingers to play the piano perfectly. But we can not assume that pianists play video games very often since no such thing is mentioned in the statement. Thus, assumption II is not correct.

Here the logic is: First, prevent the second.

Conscience : Wrong → Wrong action can be prevented by conscience.

(Conscience is the part of the personality that helps to determine between right and wrong)

Similarly,

Police : Crime → Crime is prevented by the police.

From (i), Fareeda is the sister of Hasini.

From (ii), Fareeda is the mother-in-law of Ayub.

So, Ayub should have a wife. Also children. So, Bhim cannot be the husband of Hasini as she has only one child.

Also Ayub's wife cannot be Fareeda, (She is his mother-in-law) cannot be Hasini (she is the sister of Fareeda) and cannot be Elena (she is the wife of Chetan)

So, Ayub's wife can be Gayatri and then Fareeda's husband will be Bhim and the married brother of Gayatri will be Chintu. So, the only child of Hasini will be Dada.

If each person is called with the first letter of his name, then the relationship will be as shown below.

X- married couples.

Bhim is the father-in-law of Elena.

From (i), Fareeda is the sister of Hasini.

From (ii), Fareeda is the mother-in-law of Ayub.

So, Ayub should have a wife. Also children. So, Bhim cannot be the husband of Hasini as she has only one child.

Also Ayub's wife cannot be Fareeda, (She is his mother-in-law) cannot be Hasini (she is the sister of Fareeda) and cannot be Elena (she is the wife of Chetan)

So, Ayub's wife can be Gayatri and then Fareeda's husband will be Bhim and the married brother of Gayatri will be Chintu. So, the only child of Hasini will be Dada.

If each person is called with the first letter of his name, then the relationship will be as shown below.

X- married couples.

Chintu is the brother of Gayatri

The logic follows here is:

\(\mathrm{A}=1, \mathrm{B}=2, \mathrm{C}=3, \mathrm{D}=4, \ldots \mathrm{Z}=26\)

\(\mathrm{SUN}=\mathrm{S} \rightarrow 19, \mathrm{U} \rightarrow 21, \mathrm{N} \rightarrow 14 \rightarrow 192114\)

Similarly,

\(\mathrm{TIN}  \rightarrow \mathrm{T} \rightarrow 20, \mathrm{I} \rightarrow 9, \mathrm{N} \rightarrow 14 \rightarrow 20914\)

In the same way,

\(\mathrm{THING} \rightarrow \mathrm{T} \rightarrow 20, \mathrm{H} \rightarrow 8, \mathrm{I} \rightarrow 9, \mathrm{N} \rightarrow 14, \mathrm{G} \rightarrow 7 \rightarrow 2089147\)

According to the given information,

Given Names: Sham, Ramu, Vignesh, Vivek, Mounika, Agarwal, Gupta, and Mishra.

Given Posts: Technical Director, Scientist E, Scientist D, Scientist C, Scientist B, Scientific Officer, Technical Assistant B, and Technical Assistant A.

1) Mounika holds the highest post among all.

2) Only one person have post between Mounika and Agarwal.

3) Mishra holds the lowest post among all.

4) Vignesh is senior to only two persons.

5) The number of persons senior to Vivek is the same as the number of persons junior to Gupta, who is a neighbor of Scientist D and Scientist B.

6) Gupta is a senior to Vivek, who is not a Technical Assistant B.

7) Two persons have post between Gupta and Sham.

The final arrangement will be:

So, Gupta is Scientist C.

According to the given information,

Given Names: Sham, Ramu, Vignesh, Vivek, Mounika, Agarwal, Gupta, and Mishra.
