From statement 1:

50 percent of all the teachers in the school have a masters degree, means 40 teachers have a masters degree. But no info about male and female numbers.
Insufficient.

From statement 2:

40 teachers are male. But no info about the number of teachers with a masters degree.
Insufficient.

Combining both:

40 male and 40 female teachers and 40 teachers have a masters degree.
Either all male have a masters degree or none have.
Insufficient.
E is the answer.
