How many of you want to be a doctor?

  1. How many of you want to be a doctor?
  2. How many of you wants to be a doctor?
    Which one is correct?

The first one.

Needn’t ‘a doctor’ be ‘doctors’ since a sense of plurality is expressed by ‘How many’?

  • how many of you want to be doctors.
    Yes T_H I agree with you.

For instance:
-How many of you will be doctors.

  And not

-How many of you will be a doctor. This looks grammatically awkward to me.

The original sentence includes an article.

How many of you want to be a doctor?
How many of you want to be doctors?

This is not the same as ‘will be’ so changing the verb is not an option.

I think we should also correct the error we might find in the question posted so that the poster will take note of it for future compliance. Earlier, I used to notice Bev advise the Forum members even on punctuation and spelling.

There is no error in the question of the first message of this thread.

Mr. lawrence was stressing on the plurality as in(how many), to match with doctors.

That was the query statement, not the question.
