A survey of  teachers determined the following:

 had high blood pressure

 had heart trouble

 had both high blood pressure and heart trouble

What percent of the teachers surveyed had neither high blood pressure nor heart trouble?

 

I think 30 had high blood pressure nor heart trouble but I might be wrong
