Study the histogram that shows the marks obtained by students in Maths.
By what percentage is no. of students whose obtained marks between 200 and 300 more than the no. of students whose obtained marks are between 300 and 400?
Answer & explanation
Correct answer: option 2
No. of students who obtained marks between 200 and 300 = 45 + 60 = 105
No. of students who obtained marks between 300 and 400 = 40 + 35 = 75
Required percentage = \(\frac{105 - 75}{75}\) × 100 = \(\frac{30}{75}\) × 100 = 40%
