Question : Among T, V, B, E and C, who is the third from the top when arranged in the descending order of their weights ?

Statements :
I. B is heavier than T and C and is less heavier than V who is not the heaviest.
II. C is heavier than only T.

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 E) Both I and II are sufficient

Discuss

Answer & Solution

Answer: Option A

Solution:

From I, we have: B > T, B > C, V > B. Thus, V is heavier than each one of B, T and C. But V is not the heaviest. So, E is the heaviest.
Thus, we have the order. E>V>B>T>C or E>V>B>C>T. Clearly, B is third from the top.

Question : Which word in the code language means 'flower' ?

Statements :
I. 'de fu la pane' means 'rose flower is beautiful' and 'la quiz' means 'beautiful tree'.
II. 'de la chin' means 'red rose flower' and 'pa chin' means 'red tea'.

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 E) Both I and II are sufficient

Discuss

Answer & Solution

Answer: Option D

Solution:

From the two statements given in I, the code for the only common word 'beautiful' can be determined.
From the two statements given in II, the code for the only common word 'red' can be determined.
In I and II, the common words are 'rose and 'flower' and the common code words are 'de' and 'la'. So, the code for 'flower' is either 'de' or 'la'.

Question : How many students in a class play football ?

Statements :
I. Only boys play football.
II. There are forty boys and thirty girls in the class.

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 E) Both I and II are sufficient

Discuss

Answer & Solution

Answer: Option D

Solution:

From I: “Only boys play football” tells us that if anyone plays, they must be boys, but it does not state how many boys actually play (could be anywhere from 0 to all boys). Hence, not sufficient.

From II: “There are 40 boys and 30 girls” only gives class composition; it provides no information about who plays football. Hence, not sufficient.

Together (I + II): We know only boys can play and there are 40 boys, but we still don’t know how many of those boys actually play (could be any number from 0 to 40). Still not sufficient.

Therefore: The exact number of students who play football cannot be determined from the given statements.

Statements :
I. The first serial was screened on 23rd, Tuesday and was followed by serial D.
II. Serial A was not screened on 25th and one serial was screened between serials A and B.

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 E) Both I and II are sufficient

Discuss

Answer & Solution

Answer: Option E

Solution:

From I, we know that the serials were screened on 23rd, 24th, 25th and 26th.
Clearly, D was screened second i.e. on 24th, Wednesday.
From II, we know that one serial was screened between A and B.
So, A and B were screened first and third, i.e. on 23rd and 25th. But, A was not screened on 25th.
So, A was screened on 23rd and B on 25th. Thus, C was screened on 26th, Friday.

Statements :
I. 'nik sa te' means 'right or wrong', 'ro da nik' means 'he is right' and 'fe te ro' means 'that is wrong'.
II. 'pa nik la' means 'that right man', 'sa ne pa' means 'this or that' and 'ne ka re' means 'tell this there'.

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 E) Both I and II are sufficient

Discuss

Answer & Solution

Answer: Option C

Solution:

I. In 'right or wrong' and 'he is right', the common word is 'right' and the common code word is 'nik'. So 'nik' means 'right'. In 'right or wrong' and 'that is wrong', the common word is 'wrong' and the common code word is 'te'. So, 'te' means 'wrong'.
Thus, in 'right or wrong', 'sa' is the code for 'or'. II. In 'that right man' and 'this or that', the common word is 'that' and the common code word is 'pa'. So, 'pa' means 'that'. In 'this or that' and 'tell this there', the common word is 'this' and the common code word is 'ne'. So, 'ne' means 'this'. Thus, in 'this or that', 'sa' is the code for 'or'.

II. Arvind is younger than Kamal.

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 E) Both I and II are sufficient

Discuss

Answer & Solution

Answer: Option B

Solution:

As given, we have: M > K, A > S.
From II, K > A. Thus, we have: M > K > A > S.
So, Sharad is the youngest. From I, M > S. Thus, we have: M>K>A>S or M>A>K>S or M>A>S>K.
