Hi,
Seeing the stats alone will definitely not yield an aswer since we have not restriction on the number of students we have.
However combining the 2 stats we can have only 2 values of the total number of students ,
1>either 20 so that 10% of 20 gives and integer = 2 {this is barred by stat 1}
2>or 10 so that 10% of 10 gives an integer = 1
All other values of integers between 1 and 20 will give non integer values when u take 10% of the same.
hence the correct answer is C
