Verbal Reasoning - Venn Diagrams - Discussion

OK people, lets put it the right way. No more confusion.

Option D could have been the best answer if there had been some intersecting region between the two small circles(inside the bigger circle), as people can travel by bus as well as train.
Option C is right because our approach is this way : 1. try to relate stuff 2. Do not lead to any contradiction.

Following the approach:
1. we related stuff in option D Closer than option C (hope you get what i mean by it)
2. But it lead to contradiction(as people can travel by bus as well as train.)
3. Now, trace back to the previous case, i.e. option C.

More Generally, the steps can be:

1. Arrange the options in order of increasing relationship.
ex. in this case A is more related than B.
C is more related than B.
D is more related than C.
therefore, the order is B, A, C, D.

2. Try to find some contradiction in The most related option.
ex. here it is D.

3. If contradiction not found
-> That is your answer
If contradiction found --> Repeat step 2 for the option immediately preceding The option you are on now.
Ex. We found contradiction for D.( people travel by bus & train both)
The option imm. preceding D is C, Therefore, Check For C.

No contradiction found for C, C is your Answer.
Note: This is an algorithm prepared by me for my own use. I don't claim validity of this algorithm. Still, It lands me on the correct option every time i have used it.

@Deepak : Answer cannot be D because people can travel by bus as well as train.

@Arun : Answer cannot be D because; the key to solving these type of questions is finding some kind of relationship among the given stuff. You are trying exactly opposite of it.

According to me, option C is correct.

D cannot be the answer since all travellers do not travel just by bus or train, even the people who are travelling by plane or taxi or any vehicles are called travellers.

And there is no intersection of all the three circles required since a traveller can travel by bus or train one at a time, one can not travel by bus and train at the same time, if he is to travel by train then he has to get down from the bus or vice versa.

C satisfies these 2 qualities since there is no intersection of all the three and that all travellers are shown to travel by just train and bus.

Here we go: Option D is not correct because All travelers do not travel by bus or train, they can travel on a plane, a boat or even walk.

But option C is not correct because there is no relation given for the travelers who travel by both bus and train, so the answer is the figure of question 2, option C.

Since option C is wrong we are forced to consider option B because there is a possibility of no relation among the three. Here is why, Travelers are humans, bus and train are just vehicles and we cannot combine bus and train since the word vehicle is not given in the question.

I think the answer should be A. I'll tell you the reason. It's because if you observe carefully one coach/ cart in a train is almost equivalent to a bus. So one coach can be considered as one bus. Likewise the smaller circle in A is the bus which is a part of the larger circle ie the train. And passengers are different because they are the ones who travel either by train or by bus. So i think that option A is the most apt.

Option B is correct.

Venn diagram represents the relationship between sets. Set of Trains = {train1, train2, train3,......}, set of bus ={bus1, bus2, bus3,....}, set of traveller = {human1 with ticket of bus, human2 with ticket of train, human3 with ticket of aeroplane, human4 who is pedestrian, human 5, }.

None of the elements of sets are common. So disjoint sets, then the Correct answer is B.

The answer is C. It is "Travellers" and not " Travelling".

If it was "travelling", then D is the answer. Because both Bus and Train are used for Travelling and so "train" and "bus" are two different modes used for travelling.

Whereas, in the question, it is "travellers" meaning: Travellers have the choice to either use a Bus or a Train as their mode of commute.

Hence, it is option C.

Travellers can travel by aircraft, water transport not merely train and bus. Therefore I think D is a correct option as traveller implies larger circle and inner circles represent only part of the options available to travellers. Train and bus circle cannot intersect because a person cannot travel by both modes simultaneously. Therefore I think D is the correct answer.

C is correct because bus and train two different object, you cannot overlap travelers train and bus to represent travelers who take both train and bus.

Why option D wrong.

Since not all travelers travel by bus and train only, so it can't be the parent circle enclosing both, like in D.

And also since not all that travels in bus or train are travelers.

@All

The given answer is correct.

The reason for why NOT option D ?

In the case of D, The bus or train should contain only travellers. But Drivers, Conductors, Checkers, cleaners, Packages and Goods are not travellers. So the option D cannot be the answer.

Note: We can select D if images like C, B are not given as options.

Option D: This shows two small circles within a larger circle, indicating that all train and bus users are travelers. This is the most accurate representation, as people who use trains and buses are travelers.

Correct Answer:
Option D is the best choice, as it correctly shows that train and bus users are subsets of travelers.
