Verbal Reasoning - Venn Diagrams - Discussion

If you see the diagram then you find.

If there is a trained nurse then she is in hospital<Nurses >is comman for both trained as well hospital.

So, for this 4 is the no which is full fill for both i's trained nurses are must be Hospital nurses.

Digit 2 is the trained nurses, it means she is also a hospital nurse, (4 is the nurses which have both qualities TRAINED due to which they are in HOSPITAL so 4 is our central element).

Digit 1 is the number which is nurses in a hospital it means it also be a trained nurse.

So from these three no<4, 2, 1>we got all are interchangible in nature due to the <nurse>is comman to both in (diagram notation).

In question they ask for a trained nurse so for this only two fig< square, trangle> have common words so we only go for this 2 figure.

So for total trained nurses. 4+1 and 4+2==5&6.

But for the <circle> which cover all the digit which are married population, they are not any types of nurses like trained or hospitalised so all the option related to this is canceled out, hence correct option is C (5, 6).

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.

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.

@All

Your thinking is right. But we have to choose the answer from the given options.

The options A, B, D are can be eliminated easily.

Option A = 3, 6 ; Here 3 is 'just only a married population'.
Option B = 7, 5 ; Here 7 is 'married nurses in hospital but not trained'.
Option D = 1, 1 ; Here 1 is 'nurses in hospital but not trained'.

But, Option C = 5, 6 ; Here both 5 & 6 are covered with 'Trained nurses'. Hence the required answers.

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.

My asnwer is "2". Because he clearly mentioned thatn which number represents trained nurse. Obviously 2 represnts the trained nurse. In my point of view all options are worng. Friends correct me if I am wrong.

A complete portion of trained nurses show 5, 6, 4, 2 our answer is, 5, 6, 4, 2 but when we show in option we see only 5 and 6. In another option, one number is not related to this group. So our answer is 'C'.

You gave the right answer, thanks @Nivedita and @Sundar.

As option C (5, 6) are present inside the range of trained nurses, and the rest of the numbers are beyond the range or the shape of a rectangle.

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.

See they mentioned who are the trained nurses according to given options the answer must match to the numbers (5, 4, 2, 6) one option only having 5, 6. Remaining are unknown options.
