I was going through the the english notebook of my daughter. I caught a sentence written by her teacher "How many cousins does Mr.Peter have"
and in the answer "Mr.Peter have three cousins"
I do no think the above sentences are grammatically correct
would you please help me
"How many cousins does Mr.Peter have"
How many cousins does Mr. Peter have?
"Mr.Peter have three cousins"
Mr. Peter has three cousins.
All the best.
