Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 39
Sum of the number of boys in Science stream in the years 2012 and 2016 = 40 + 38
⇒ 78
Number of girls for all the years in the Commerce stream = 45 + 42 + 38 + 34 + 41
⇒ 200
⇒ Required percentage = (78/200) × 100
⇒ 39%
