30
let total students are x

actual failed students = fail in history + fail in geography - fail in both subjects

actual failed students = 30 % + 35 % - 27 %

= 65 % - 27 %

= 38 %

so pass students are 100% - 38 % = 62 %

but it is 248

so 62 % --------- 248 students
then 100 % ---------- x students

x = 248 × 100 / 62

x = 400 students
