Study the given histogram that shows the marks obtained by students in an examination and answer the question that follows.
If the total marks obtained by students be represented as a pie chart, then the central angle corresponding to marks 250 or more but less than 300 is: (correct to the nearest degree)
Answer & explanation
Correct answer: option 2
Total marks = 30 + 45 + 60 + 35 + 35 + 40 + 35 = 245
Marks B/w 250 & 300 = 60
Required Central angle corresponding to Marks B/w 250 & 300 = \(\frac{60}{245}\) × 360º
= 88.16º
= 88º (correct to the nearest degree)
