Explanation

Statement I alone is insufficient: Reena's position (9th left, 7th right) tells us total students = 15, but not how many are girls. Statement II alone is insufficient: The 1:2 ratio alone doesn't give the actual count. Together they are sufficient: Total = 15, ratio 1:2 means girls = (2/3) × 15 = 10.
