Question 1
4 / -1

The question below consists of 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. Read both the statements and give an answer.

Gaurav ranks eighteenth from the top in a class. What is his rank from the last?

Statement:

I. There are 47 students in the class.

II. Jatin who ranks 10th in the same class ranks 38th from the last.

A
I alone is sufficient while II alone is not sufficient

B
II alone is sufficient while I alone is not sufficient

C
Either I or II is sufficient

D
Neither I nor II is sufficient

Solution

From I, we conclude that in a class of 47 students, Gaurav ranks 18th from the top and hence 30th from the last.

From II, we conclude that there are 9 students above and 37 students below Jatin in rank. Thus, there are (9 + 1 + 37) = 47 students in the class.

So, Gaurav who ranks 18th from the top, is 30th from the last.

Question 4
4 / -1

In each question below is given a statement followed by two conclusions numbered I and II. You have to take each of the given statements in the statement to be true, then consider both the conclusions together and decide which of them logically follows from the given statement and choose your answer accordingly.

Statements: All organized persons find time for rest. Despite her very busy schedule, Sunita finds time for rest.

Conclusion:

I. Sunita is an organized person.

II. Sunita is a hardworking person.

A
Only conclusion I follows

B
Only conclusion II follows

C
Either I or II follows

D
Both I and II follow

Solution

Sunita's schedule is very busy. It means that he is hardworking. But still she always finds time for rest. It means he is an organized person. Hence both I and II follow.
Question 5
4 / -1

In each question below is given a statement followed by two conclusions numbered I and II. You have to take each of the given statements in the statement to be true, then consider both the conclusions together and decide which of them logically follows from the given statement and choose your answer accordingly.

Statement: The best evidence of India's glorious past is the growing popularity of Ayurvedic medicines in the West.

Conclusions:

I. Ayurvedic medicines are not popular in India.

II. Allopathic medicines are more popular in India.

A
Only conclusion I follows

B
Only conclusion II follows

C
Either I or II follows

D
Neither I nor II follows

Solution

The popularity of Ayurvedic or allopathic medicines in India is not being talked about in the statement. So, neither I nor II follows.
Question 6
4 / -1

In the question below are given three statements followed by two conclusions I, II. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

Statements:

Only a few mangoes are trees.

No tree is banana.

All bananas are apple.

Conclusions:

I. At least some mangoes are banana.

II. Some apples are not trees.

A
Only I follows

B
Only II follows

C
Either I or II follow

D
Both I and II follow

Solution

The least possible Venn diagram for the given statements is as follows:

Conclusions:

At least some mangoes are banana → False (as some mangoes are tree and no tree is banana).

Some apples are not trees → True (as all bananas are apple and no tree is banana).

So, Only II follows.
Question 7
4 / -1

In a certain code 'SEQUENCE' is coded as 'FDOFVRFT'. How is 'CHILDREN' coded in that code?

A
OFESJMID

B
OFSEMJID

C
OFSEJIMD

D
OFSEJMID

Solution

Reverse the word and +1 to each letter. The reverse of CHILDREN is NERDLIHC.

Add 1 to each letter. Therefore, the code of CHILDREN becomes OFSEMJID.
Question 8
4 / -1

Three different positions of the same dice are shown, the six faces of which are shown in numbers 1 to 6. What will be on the face opposite '5'?

A
3

B
1

C
4

D
2

Solution

From dices,

1, 5, 3, and 2 cannot be opposite to 6. Therefore 4 must be opposite to 6.

1, 5, 6, and 4 cannot be opposite to 3. Therefore 2 must be opposite to 3.

Therefore, 1 will be at the opposite of the face showing 5.

The first two letters are reverse positional of each other.

The 3rd letter is obtained by shifting the 2nd letter to 5 places.

Option (D) does not follow the pattern.
