im not sure but i think you take 3.35-3.10=0.25
then you put 0.25/3.35=0.07462...=0.07(2dp)
then times 0.07 by 100 to get the percentage
so 0.07x100=7

so i think its 7%

ive checked it its about right 

coz:
3.35/100x7=0.2345
then you do 3.35-0.2345=3.1155

3.1155 is about 3.10 ish :)

hope this helped
