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
