Let's let "x" be the original number of dolls in Lucy's doll collection. Then, 2 dolls equals an increase of 25%, and this can be written as x * 0.25 = 2. Solving for x we get x = 2 / 0.25 = 8 dolls in Lucy's original collection. After the gift of two new dolls, Lucy's collection contains 8 + 2 = 10 dolls.
The final answer: 10.
