Question

The Venn diagram represents enrollment in various classes at a certain high school. 12 students take math (Math) only. 11 students take English (Eng) only. 16 students take biology (Bio) only. 30 students are enrolled in math and English, but not biology. 15 students are enrolled in all three classes. 200 students attend the school, and 16 students take biology and English, but not math. How many students are enrolled in math and biology, but not English? A. 12 B. 17 C. 75 D. 100

Answer 1

the possible venn diagram is as the above.... and taking a closure look at the data... there are 200 students attending the school and the data is given of only 100 students.... also a/venn diagram, no student have taken bio and maths both other than english....
Calculating the answer separately for maths and bio gives the answer 28 which is not in option...
The data of rest 100 students is invisible (or you can say a mystery).... I'm not giving any exact answer... bt tell me your opinion too....
