Official Solution:

We’ll go for LOGICAL because that is our first choice in Data Sufficiency.

The question asks us about the new percentage of milk chocolate pralines, so we’ll start by finding the original percentage: $$\frac{10}{10 + 6 + 4}=\frac{10}{20}=\frac{1}{2}= 50\%$$. So, we are being asked whether the new pralines increased the milk chocolate percentage. (1) Knowing the number of pralines added without knowing their composition doesn’t help us determine the new percentage. (A) and (D) are eliminated. (2) If the percentage of milk chocolate in the added pralines is greater than the percentage in the original amount, the new amount must have an increased percentage. (C) and (E) are eliminated.

The answer will change if you put x as 5 or x as 10. so, 2 is not sufficient for the conclusion
