b)no of boys who passed the exam=3840

  no. of girls who passed the exam=2880

c)percentage of boys who passed the exams=48%

  percentage of girls who passed the exams=40%

Step-by-step explanation:

total candidates =8000

no. of boys = 60%of 8000

                   = (60/100)×8000

                   =4800

a) no. of female candidates= 8000-4800

                                         =3200

b)no of boys who passed the exam=80%of4800

                                                          =(80/100)×4800

                                                          =3840

no. of girls who passed the exam=90%of3200

                                                       =(90/100)3200

                                                       =2880

c)percentage of boys who passed the exams=(no. of boys/total candidates)×100

                                                   =(4800/8000)×100

                                                   =0.48×100

                                                   =48%

percentage of girls who passed the exams=(no. of girls/total candidates)×100

                                                  =(3200/8000)×100

                                                  =0.4×100
