use awk:

awk -F, -v OFS="," '/apple/{$3="whatever"}7' file

but if you don't have gnu awk 4.1, you have to do this to write back to the file:

awk -F, -v OFS="," '/apple/{$3="whatever"}7' file >~/foo.tmp && mv ~/foo.tmp file

Use sed like this:

sed -i -r 's/(apple)(,[0-9]*)?$/\1,10/'

sed -i -r 's/(apple)(,[0-9]*)?$/\1,20/'

sed -i -r 's/(apple)(,[0-9]*)?$/\1,30/'
