Answer & solution
- A
200
- B
180
- C
190
- D
170
175
Solution
Total no of majors in Physics across all geographical locations = 18 + 36 + 80 + 40 + 23 + 28 = 225
Now students majoring in Physics account for 18% of all students
∴ 18% of total number of students = 225
∴ Total number of students = 225/0.18 = 1250
∴ No of students majoring in Physics = 14% of 1250 = 125 + 50 = 175
Hence, option (e).
