from which/ of which

[elcholandes]

Dear all,

I have a problem and have doubts about the differences between:
"from which" and "of which"

For instance, is the following sentence correct?

Currently, there are around 120 employees working for PPM from which 97% are Mexicans and the remaining dutch.

Could I also use of which? what is the difference?

Thanks in advance,

J.L.S

I'd say "of whom", as you're talking about people.

It's 97% of something, not 97% from something

 

[elcholandes]

thank you very much.

Definitely.

'There are around 120 employees working for PPM of whom 97% are Mexicans and the remaining dutch.'
Is this sentence OK?
Thanks.
