Question

If 30% students failed in English, 45% failed in Math
and 25% failed in both then the student who pass in
both subject is?​

Answer 1

Answer:

Let total students 100 . 30 + 45 = 75 failed in math + english total , but you see 25 students that failed in both counted twice so minus them once .

So fail students = 75 - 25 = 50

And pass = 100 - 50 = 50℅
