Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 385.7%.
Number of students obtaining less than 350 marks = 30 + 45 + 60 + 35 = 170
Number of students obtaining more than 400 marks = 35
Percentage increase in the number of students obtaining less than 350 marks to more than 400 marks = (170 - 35)/35 × 100
⇒ 385.7%
