Step-by-step explanation:
students failed in english only 70- 65 =5 %
students failed in mathematics only 65- 25 = 40%
students failed in one or both subjects (25 +40 +5)= 70%
students who passed in one or both subjects =(100- 70)%=30%
let the total number of students be x
30% of x =3000
30/100x =3000
x = 3000×100/30
x=10000
