Statement 1: Could 1 friend, could have 2 friends...etc... Not Sufficient
Statement 2: Same logic as the first statement. Could have given 1 piece of candy out, could have given 2 pieces of candy out..etc.. Not Sufficient.
Statements 1&2 Together: Could have 1 friend (total of 15 pieces of candy), Could have 2 friends (total of 23 pieces of candy)...etc... Not sufficient.

So basically this question is testing the concept of remainders?

Yes, you can easily express it in remainder terms.

N = QD + R

N - Total candy she had at the beginning
Q - No. of friends (the quotient)
D - No of candies given to each friend (the divisor)
R - No of candies she is left with (the remainder)

To get the value of N, you need to know Q, D and R.
Statement 1 gives you D and statement II gives you R.
You still don't have Q i.e. the number of friends so you cannot find N.
