This a vague question because it depends on the candidate and their merit as well. In 2014, 13.6 lakhs students sat for the IIT-JEE exams and only 9,784 seats were available in all the IITs put together. That's an acceptance rate of only 0.7 per cent. Even though the IIT-JEE exam is extremely tough, the number of aspirants keeps on increasing every year.
