25 of the 40 begin with A or O.
14 letters do not appear, so 10 letters are left.
I don't see how they can say that 6 begin with some other letter. It is clear that since 15 names begin with one of the 10 letters, so there are 5 left over. That does not mean that all 5 of the extras begin with the same letter.
The surnames of 40 children in a class arranged in alphabetical order. 16 of the surnames begins with O and 9 of the surname begins with A, 14, of the letters of the alphabet do not appear as the first letter of a surname
If more than one surname begins with a letter besides A and O, how may surnames begin with that letter
They got 6 but I want to know how in proper analysis
Thanks

Maybe the question was intended to be
If only one letter besides A and O begins more than one surname, how may surnames begin with that letter?
Then 6 would be the answer.
