Step-by-step explanation:
Student Passed in English =80%
Students failed in English=100%−80%=20%
Students passed in Maths =70%
Students failed in Maths =100%−70%=30%
Students failed in both =10%
Total failed students = Failed in English + failed in Math − Common
Total fail students =20%+30%−10%=40%
If 40% failed then 60% will be passed
I hope it's helped you.
