Verbal Reasoning - Venn Diagrams - Discussion

I do not understand the question, as the answers are inconclusive. The question does not state limitations that conclude on answer C) , one would only get this answer right due to fact that 5&6 are the only elements that represent the trained nurses subset.

Answer is true as we have to choose relevant answer or answer which is most true from available options.

Actually, they asked about trained nurses so they may be married or they are in the hospital the common point must be that they should be trained so the answer is 'c' as the other options are not satisfying the above condition. In first 3 represents only married but not trained so it will not satisfy. In second option 7 represents married nurses in hospitals it doesn't give an idea about training so it's not correct. In 4th option, 1 represents only nurses in hospital but gives no idea about training so it's not relevant to the above condition.

As the TRAINED NURSES is represented by the square box we should consider the digits.

i.e. 2, 4, 6, 5.

5 4 6 2 so the numbers were matching with c if we exclude a band d due to (3 7 1) which are not applicable hence taken it as 5 and 6.

Is that the correct way of thinking? Please tell me.

Option wise:

1) 3 & 6 where 3 represents the only married population and " NOT TRAINED", and 6 represents who is married and trained.

2) 7&5 where 7 represents married and nurses in the hospital that means eventually they are " Not trained" and 5 represents married, trained and nurse in the hospital.

4) 1&5 where 1 represents only nurses in the hospital who are " NOT Trained" and 5 represents married, trained and nurses in the hospital.

3) 5 & 6 which is correct according to me,
because 5 represents married, trained and nurses in the hospital and 6 represent married and trained nurses.

Question asked is only for trained ones, so 5 and 6 is the only option where 5 and 6 are both trained.

And option 1,2,4 are the options where only one number among them represent trained nurses.

Here, trained nurses represented by 2, 4, 5, 6 clearly.

The rectangle represents trained nurses.

I am not getting this, please explain me.

The Correct answer is 2. In my point of view.

I am not getting this. Please, anyone explain the answer.
