1000 students appeared for the talent search examination NCERT. The examination had 1000 questions. During checking of the papers, a very peculiar trend was noticed. The first student attempted all the questions, the second student attempted questions with question numbers which were multiples of 2, the third student attempted the questions with question numbers which were multiples of 3 and so on.

Let f(n) = the number of students who attempted the question number n

For example, f(10) represents the number of students who attempted the question number 10 and f(10) = 4 because four students (1st, 2nd, 5th and 10th) attempted the question.

For how many questions was f(n) odd?
OPTIONS
 
 1)234
 2)31
 3)78

 5)None of these
