Question 11
Questions : In a certain code, 'XYZ' means 'we are friend'. Which letter stands for 'We' ?

A
Only II
B
Only I and III
C
All I, II and III
D
Either I only or II only
E
None of these
Correct Answer: Option E

To find the code for 'we ', we need to have any of the following :

(i) 'We are friends' should have only 'We' common with another statement, as in II;

(ii) 'We are friends' should have only 'are' and 'friends' common with another single or two statements, as in I and III.

Thus, we need Either II only or I and III only.

Correct Answer: Option A

Given : P < S, T < R

From I, we have : P < R

From II, we have : R < S

From III, we have : Tom is the youngest.

From (i) and (ii), we get : P < S, T < R < S. So, Sonali is the oldest.

Question 13

Correct Answer: Option D

From I, we have : M > V, V > S, V > N.

From II, we have : Mukul is the oldest.

From III, we have : S > N

Combining (i) and (iii), we get : M > V, V > S > N or M > V > S > N.

Clearly, Nikunj is the youngest.

Correct Answer: Option E

From I and II, we conclude that Mathematics Period began at 9.00 a.m. , Biology period began at 8.00 a.m. and Physics period began at 11 a.m. So, the Chemistry period began at 10.00 a.m.

Question 15

Statements:

I.   Vasu's basic salary is Rs. 100 more than Rajan's salary who also serves in Vasu's company.

A
Only II
B
Only II and III
C
only I and II
D
only I and III
E
All I, II and III
Correct Answer: Option E

From III, we have : Rajan's basic salary = Rs. 1550.

From I, we have : Vasu's basic salary = Rs.(1550 + 100) = Rs. 1650.

From II, we have : Rajan's other allowances = Rs. 2050.

and Vasu's other allowances = Rs. 2050.

so, Vasu's monthly salary = Rs. ( 1650 + 2050) = Rs. 3700.
