Besides the fact that 40 failed both ways; I can't tell you anything more. If I had a percentage of these students; I could tell you something.

You're asking for an amount. You've got me thinking. Eng-20% failed. 15% failed in math. So Eng/5+Math/6.66=40students. Between the 2 subjects there's 114 students.

The formula I used is x/5+x/6.66=40
