The question says we have to find the number of students enrolled Full time 1999 and 2000.

Statement I -

Full Time students
1999 = x
2000 = 50+x

But we dont know x, therefore we cannot find the % increase.

Not Sufficient.

Statement II -

5 % increase in TOTAL NUMBER OF STUDENTS.

We dont know the segregation of full time students and part time students.

Not Sufficient.

Combining Statement I & II (cant conclude anything) Everything remains the same as above.

Hence E is the answer.
