Remaining 100-60=40%pass

Answer 2

Answer:40%

Step-by-step explanation:

passed in mathematics = 40%

passed in the English=30%

student passed in both subjects =10%

so student passed in mathematics only = 40%- 10%

                                                                     = 30%

and student passed in the English only = 30%-10%

                                                                     = 20%

so total passed student = 30%+20%+10%

                                          = 60%

so student who failed in both subjects = 100%-  60%

                                                                   = 40%

so total 40% student failed in both subjects.
