in first subject 35%is fail =2500×35/100

=875 students are fail in first subject.


similarly in second subject , 2500×42/100=1050students are fail.

in both subject,2500×15/100=375students are fail.

in first subject no of pass student=2500-875=1625

in second subject no of pass student =2500-1050=1450.

in. both subject no of pass student =2500-375=2125
