Logical 18 - Puzzle Test

Key Points to Remember:

Puzzle Test is of Analytical Reasoning comprising of questions in the form of puzzles involving certain number of items. We have to analyze the given information, condense it in a suitable form and answer the questions asked.

The various types are:

1. Classification Type Questions
2. Seating / Placing Arrangements
3. Comparison Type Questions
4. Sequential Order of Things
5. Selection Based on Given Conditions
6. Family - Based Problems
7. Jumbled Problems

Let's see some Classification questions here. This type of questions in which certain items belonging to different groups or possessing different qualities are  given along with some clues with the help of which we have to group and analyze the given items and answer the questions accordingly. 

Question Set 1:

Study the following information carefully and answer the given questions:

• B and E are good in Dramatics and Computer Science.
• A and B are good in Computer Science and Physics.
• A, D and C are good in Physics and Mathematics.
• C and A are good in Physics and Mathematics.
• D and E are good in History and Dramatics.

1. Who is good in Physics, History and Dramatics?

a) A     b) B     c) D     d) E

2. Who is good in Physics, History and Mathematics, but not in Computer science?

a) A     b) B     c) C     d) D

3. Who is good in Computer Science, History and Dramatics?

a) A     b) B     c) C     d) E

4. Who is good in History, Physics and Computer Science?

a) A     b) B     c) C     d) D

5. Who is good in Physics, Dramatics and Computer Science?

a) A     b) B     c) C     d) E

Solution:

	Dramatics	Computer Science	Physics	History	Mathematics
A	X	√	√	√	√
B	√	√	√	X	X
C	X	X	√	√	√
D	√	X	√	√	X
E	√	√	X	√	X

The given information have been analyzed and the details furnished are in the table.

Thus,

1. D is good in Physics, History and Dramatics. So, the answer is (c).

2. Both A and C are good in Physics, History and Mathematics. But, A is good in Computer Science, while C is not. So, the answer is (c).

3. E is good in Computer Science, History and Dramatics. So, the answer is (d).

4. A is good in History, Physics, Computer Science and Mathematics. So, the answer is (a).

5. B is good in Physics, Dramatics and Computer Science. So, the answer is (b).

Question Set 2

• Five Friends P, Q, R, S and T traveled to five different cities of Chennai, Kolkata, Delhi, Bangalore and Hyderabad by different modes of transport of Bus, Train, Aeroplane, Car and Boat from Mumbai.
• The person who traveled to Delhi did not travel by Boat.
• R went to Bangalore by Car and Q went to Kolkata by Aeroplane.
• S traveled by Boat whereas T traveled by Train.
• Mumbai is not connected by Bus to Delhi and Chennai. 

1. Which of the following combinations of person and mode is not correct?
a) P - Bus
b) Q - Aeroplane
c) R - Car
d) S - Boat
e) T - Aeroplane

2. Which of the following combinations is true for S?
a) Delhi - Bus
b) Chennai - Bus
c) Chennai - Boat
d) Data Inadequate
e) None of these

3. Which of the following combinations of place and mode is not correct?
a) Delhi - Bus
b) Kolkata - Aeroplane
c) Bangalore - Car
d) Chennai - Boat
e) Hyderabad - Bus

4. The person traveling to Delhi went by which of the following modes?
a) Bus
b) Train
c) Aeroplane
d) Car
e) Boat

5. Who among the following traveled to Delhi?
a) R 
b) S
c) T
d) Data Inadequate
e) None of these 

Solution:

The given information can be analyzed as follows:

Mode of Transport - R travels by Car, Q by Aeroplane, S by Boat and T by Train. So, P only remains. And P travels by Bus.

Place of Travel - R goes to Bangalore, Q to Kolkata, No Bus Transport for Delhi and Chennai. So, P who travels by Bus, goes to Hyderabad. S travels by Boat and not to Delhi. So, he goes to Chennai. And T goes to Delhi, the final one. 

Person	P	Q	R	S	T
Place	Hyderabad	Kolkata	Bangalore	Chennai	Delhi
Mode	Bus	Aeroplane	Car	Boat	Train

1. Clearly, the incorrect combination is T - Aeroplane. So, the answer is (c).

2. Clearly, the correct combination is S - Chennai. So, the answer is (c).

3. Clearly, the incorrect combination is Delhi - Bus. So, the answer is (a).

4. Clearly, T traveled by Train to Delhi. So, the answer is (b).

5. Clearly, T traveled to Delhi. So, the answer is (c).

Time to Think:

There are six persons - A, B, C, D, E and F in a school. Each of the teachers teaches two subjects, one compulsory subject and the other optional subject. D's optional subject was History while three others have it as compulsory subject. E and F have Physics as one of their subjects. F's compulsory subject is Mathematics which is an optional subject of both C and E. History and English are A's subjects but in terms of compulsory and optional subjects, they are just reverse of those of D's. Chemistry is an optional subject of only one of them.
