What is the ratio of the number of students of science stream of schools A, B, and D taken together to the number of students of vocational stream in schools B, D, and E has taken together? Correct Answer 89 ∶ 65

Total students in vocational stream from school B, D, and E = 40 + 40 + 50

⇒ 130

Ratio = 178 : 130

⇒ 89 : 65
