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=2>>2.
Solving for x we get x=2/0.25=<<2/0.25=8>>8 dolls in Lucy's original collection.
After the gift of two new dolls, Lucy's collection contains 8+2=<<8+2=10>>10 dolls.
