A. 30
B. 40
C. 50
D. 60
E. 70



Total = 500

Republican = 200

democrats = 300.

Vegetarians = 100

Non vegetarians = 400.

Non vegetarians democrats = 270

Non vegetarians republicans = 130.

Democrats vegetarians = 300 -270 = 30.

Republicans Vegetarians = 200 - 130 = 70.

E is the correct answer.
